The Japanese government held a relevant cabinet meeting on the morning of April 13 and officially decided to discharge nuclear waste water from the Fukushima Daiichi Nuclear Power Plant to the ocean, which is harmful to the marine environment.

According to Japan’s own statement, it is only a decision now, the actual discharge will be delayed until two years later, and the discharge will dilute the nuclear waste water to one-seventh of the radiation safety standards for drinking water established by the WHO. According to Japanese standards, this is actually equivalent to no discharge, because under the Japanese bureaucratic system, “postponing” can be equated to “shelving”, or not for the time being for now, as for the future. They choose to maintain strategic determination and believe in the wisdom of future generations. By the way, the main reason for the previous discharge decision is that the existing storage tank capacity is about to be used up in September next year, and now 140 tons of nuclear waste water are added every day. As for how to give the newly added 140 tons per day after September next year Drink it or discharge it, this is a matter of the wisdom of future generations. To solve this problem, the root is not in technology or engineering, and technology cannot be discussed in terms of technology. In the early revolutionary war years, there was a saying used to criticize military personnel, called “pure military viewpoint.” Now many people discuss this issue and fall into “pure technology.” This is actually a political issue. Since the Fukushima nuclear accident occurred in 2011, it has been dragged on for 10 years. It has been dragged down to the point where it is out of control today. The root lies in Japan’s wisdom for future generations. Maintaining a high degree of trust, the Fukushima nuclear accident occurred during Naoto Kan’s tenure, and then the term of Yoshihiko Noda was delayed, and then the entire term of Shinzo Abe was delayed. Abe was the longest-term prime minister in Japanese history. Now in the tenure of Yoshihide Suga, considering the deep trust of the first three prime ministers in the wisdom of future generations, Yoshihide Suga naturally has no reason to break this tranquility and will definitely continue to believe in the wisdom of future generations. In short, the wisdom of future generations is infinite, as long as you maintain full trust in the wisdom of future generations, then no matter how big things can be dragged on, it will not be said that it will be ten or eight years, that is, for generations to come, the same as the world. Shou is not surprising. As for the consequences will become more and more serious? Maybe it will, but the wisdom of future generations will also increase in the same proportion. There are endless descendants, and infinite wisdom will surely solve the problem of infinity. As long as you keep dragging, you can always win, win countless times, and win.

Japan has officially decided to discharge Fukushima nuclear sewage into the sea. You have already said a lot. Let me talk about a rather funny thing, how the Japanese media is maliciously oriented. First look at this picture. The title states that the media in neighboring countries and regions are very worried about nuclear sewage discharge, and the United States understands it. This title has divided the enemy and our camp. The neighboring countries must be China and South Korea. These two bad guys have been against us. Not surprisingly, let them go. Fortunately, American fathers have always supported us. It is so happy to have American fathers. Alas…I’ve not always been very supportive. My little brother 4V has joined the anti-Japanese camp. It turned out to be the pro-Chinese media “China Times”. Just look at the name and you will know that this is an anti-daily newspaper. It’s not bad. Most of 4V still loves Da Ge Ge Yes, will not betray me. In fact, even the juicy new head shells are reporting. 4V’s official newspaper, Central News Agency, is reporting that the 4V that has always been eaten by Da Ge Ge is scared to death when he hears of nuclear waste water. For such a multimedia report, he just quoted the “China Times”, which is too powerful. This is a classic case of Japanese media manipulating public opinion. To sum up, those who oppose me are all anti-Japanese elements. Not surprisingly, those who turned their elbows away were traitors, a small group of people. Except for China and South Korea, most people support our platoon. Wastewater.

In fact, it is really not troublesome to resolve this matter. The United States and Japan said they wanted everyone to withdraw and the Security Council would take over. Then evacuate all the people around Fukushima, as clean as possible. The Japanese government is not willing to make the Security Council accountable. Just watch the Japanese government next to it. After the withdrawal was completed, several countries in the Security Council made a joint effort, and no one’s media said anything. Then China, Russia, and the United States could do it to ship the nuclear bombs to Fukushima. Then, the amount is calculated, the civilians are evacuated out of the visible area, the nuclear bomb is detonated, and the problem is solved. The problem is… the difficulty of this matter is not whether the matter itself is well done, but the first thing behind it: Japan must be able to hand over Fukushima to the Security Council with peace of mind. Secondly: the countries of the Security Council can negotiate well, at least cooperate in this matter. But the problem is: on the first point, Japan is unwilling, and on the second point, the United States is unwilling. So to put it bluntly, Fukushima is a human problem from beginning to end. In the past, it was the Japanese government that was unwilling to take responsibility. Now it is the Japanese government that does not want others to be responsible for it. All in all-anyway, the world will suffer in the end, and no one can escape. Don’t look at the Americans indulging in Japan, the victimized country must have his share. As for what the Japanese say will reduce radiation… the ghost believes it!

Where will the nuclear waste water drift? One sentence is, first drift to the United States, and then drift back again! How exactly did the public information drift? Based on a rough analysis of ocean currents, nuclear wastewater may not only affect Japan, but also countries or regions along the Pacific Ocean. The Japanese warm current will first flow seawater to the northeast, and finally reach the waters of Alaska in North America, and then after a period of touring, following the Alaska warm current, the California cold current, the northern equatorial warm current, the equatorial countercurrent, the southern equatorial warm current, the Japanese warm current, etc. The entire North Pacific cycle was gradually diluted and eventually returned to the vicinity of Japan. There are more than ten coastal countries and regions, and the total population of these countries and regions is about 1 billion. Will China be affected? In theory, the coastal areas of mainland China are not greatly affected for four reasons. 1. Sufficient preparation time-because the discharge point Fukushima is on the east coast of Japan and at the end of the Japanese warm current, and the Japanese warm current is a strong ocean current from south to north, nuclear waste water will only follow the Japanese warm current to north and west. Go, first to Canada and the United States, the first time can not be close to the coastal waters of mainland China. 2. Treasure Island, Taiwan—The nuclear waste water will follow the ocean currents and make a circle in the North Pacific before reaching the vicinity of Taiwan, China. 3. Water cannot flow to high places-due to the existence of two submarine steps, especially the steep rise of the submarine steps close to mainland China, coupled with the barrier of Taiwan Island, it is difficult for ocean currents to cross this step on a large scale, so The Japanese warm current is formed and flows to the east coast of Japan. 4. Clear pressure difference between the Yellow River, the Yangtze River, and the Pearl River—the Yellow River, the Yangtze River, and the Pearl River are all injecting water resources into the coast of mainland China all the time. The strong pressure difference forms a natural water barrier. The principle is similar to “the Yellow River, the Yangtze River, and the Pearl River.” At the same time, the Ministry of Foreign Affairs of China has issued a statement that it is highly concerned about this incident, and the country has a “National Nuclear Emergency Plan”. If there is a risk in this regard, the country will definitely give a risk warning. You can just follow the news. How long will it affect China? If Li Xueyao returned to Eastern Asia as the time node, he might return within the year, but because of the above factors, the impact will be slower and there will be a certain amount of protection time. But this matter is irreversible in nature, and the world will be affected sooner or later!

After several days of attention, I came to the following conclusion: This is a field with strong professionalism and extremely high barriers to entry. There are only a handful of nuclear practitioners and respondents with relevant professional certifications under related topics. Pure emotional venting is meaningless except to occupy the high ground of public opinion, increase worries, and create anxiety. For the people, the best response is to believe that the party, the state and experts in related fields will make correct and reasonable judgments and actions. If the country does not speak out, it means that there is no problem. If the country announces sanctions or other actions, then Just support all decisions of the country. Everyone has limited energy, “If it is not necessary, don’t add more entities.” After answering, I wish you all safety and health. The first time I received so many replies, I couldn’t reply. I am glad to see that everyone has different voices, although there are some meaningless replies. I am just an ordinary person with limited knowledge and no professional knowledge to write professional answers. I just wrote what I thought, shared some views, and hoped to do something within my power. I didn’t expect so many people to watch it. But today’s Internet environment is really bad enough, is it a derogatory term for the sake of others? I understand that everyone’s cognitive level and living environment are different, but it is not advisable to save others by oneself. I hope everyone can have a friendly discussion.

The specific impact and harm of nuclear sewage on the environment and humans is serious. It is necessary to estimate the amount of radioactive substances contained in the nuclear sewage, and to what extent these substances can be diluted after entering the seawater, so as to estimate the effects of these radioactive substances on the environment. What dose of radiation might be caused. There seems to be a lack of reporting information in this area in the current media. They only say that there is such a thing as the discharge of nuclear sewage, but rarely see domestic media reports on the radiation dose and the mechanism of harm. Here is a quote from a popular science answer I wrote earlier to explain the possible harm of nuclear sewage [1]. Nuclear sewage contains radioactive substances. First of all, it needs to be clear that there are three ways for radioactive substances to enter the human body: 1. Respiratory system: People inhale oxygen through the respiratory system and discharge carbon dioxide. When we breathe, we will inhale a large amount of foreign matter. Some of these foreign matter are gases and some are particulate matter (such as dust, PM2.5, etc.). Gas enters the lungs freely, and then into the blood, the amount of entering the blood depends to some extent on the solubility of the gas. A small part of the inhaled particulate matter will be deposited in the lungs, and the rest will be exhaled or deposited in the upper respiratory tract and swallowed. If there are radioactive materials in the air or dust, the respiratory system provides a way for the radioactive materials to enter the human body. 2. Digestive system: When we eat food or drink water, the food or water may contain soluble or insoluble radioactive contaminants. Soluble radioactive pollutants are ingested through the oral cavity, and after digestion through the digestive tract, they can be transported by the blood along with the absorption of nutrients, and the blood brings them to various parts of the body. Insoluble radioactive pollutants pass through the digestive tract and are excreted from the feces. When these radioactive materials pass through the human body, the digestive tract and large intestine will be irradiated. 3. Circulatory system: The circulatory system is a closed pipe system in the human body, including the blood system and the lymphatic system. After the respiratory system and digestive system, which have been mentioned above, ingest radioactive materials, the radioactive materials can be transported to various parts of the body with the blood through the circulatory system. Then we need to know how radiation interacts with cells: the human body is composed of cells, and cells constitute various organs and tissues of the human body. The basic components of a cell are the nucleus, cytoplasm and cell membrane. Among them, the nucleus contains chromosomes. The chromosomes contain human genetic genes, so-called deoxyribonucleic acid (DNA), which can determine cell characteristics and information. In fact, most of the cells are water. Radioactive substances decay or ionize in water, which will produce radiation. These radiations hit DNA molecules and may cause changes in the structure of DNA. Depending on the amount of radioactive material ingested, the intensity of radiation, and how much DNA molecules are changed, the cells may die early, prevent cell division or delay cell division, etc., resulting in permanent cell deformation. If the radiation of radioactive materials enters the reproductive system, it may affect the reproductive cells and make people infertile. It is said that in the previous accelerator experiments, the conditions for radiation protection were not good. When repairing accelerators, experimenters generally did not allow young people who were not married and had no children to participate, because they were afraid of affecting fertility. Let me introduce several kinds of radiation and hazards produced by radioactive materials: the radiation type alpha particles produced by radioactive materials: large mass, with 2 positive charges, in fact, they are helium ions, which have a short range in the material. The range of alpha particles in the air is only a few centimeters, and it is difficult for the human body to penetrate the stratum corneum on the surface of the human skin. Therefore, alpha particles are almost harmless outside the human body. However, once alpha particles enter the human body, the radioactive material that produces alpha particles is surrounded by living tissues of the human body, and the released alpha particles are deposited in an organ in the human body. The energy of the alpha particles will be absorbed by the organ, and the organ may be affected. Serious damage. Beta particles: Beta particles are actually electrons, and the range of electrons in the air is farther than that of alpha particles. Beta particles can penetrate human skin into superficial tissues a few millimeters. Therefore, even outside the human body, beta particles have a certain degree of harm, but they are relatively minor. When entering the human body, beta particles are less harmful than alpha particles. The range of beta particles in human tissues is longer, and the energy deposited in human tissues is smaller than that of alpha particles, which causes less damage. Gamma rays: Gamma rays are actually high-energy photons. They have a long range and strong penetrating power. Even if you are far away from the radiation source, gamma rays may irradiate you. Strong penetrating gamma rays can affect all The organs and tissues are irradiated. On the other hand, because γ-rays have a long range in human tissues, they can even penetrate the human body, which makes it deposit less energy in human tissues and cause less damage. In other words, the damage caused by γ-rays outside the human body is greater than that of α particles and β particles, and the damage caused by γ-rays inside the human body is less than that of α particles and β particles. Neutrons: Like gamma rays, neutrons are not charged and have a long range. The main harm of neutrons to the human body is radiation outside the human body. The energy carried by neutrons is generally higher than that of gamma rays. At the same dose, neutrons are much more harmful to the human body than gamma rays. So, how could the nuclear sewage discharged from the Fukushima nuclear power plant cause harm? The nuclear sewage from the Fukushima nuclear power plant was treated before it was discharged, but the sewage still contains carbon 14 (and tritium), which can undergo beta decay and release beta particles. If people eat food that has been contaminated by nuclear sewage, such as fish caught in the sea, they may ingest radioactive substances, such as carbon 14. When carbon 14 decays in the human body, the beta particles produced may cause the structure of human DNA Change, cause harm, such as causing leukemia, cancer, etc. The above is a simple mechanism and process of radiation hazards, but in reality, whether the nuclear sewage discharged from the Fukushima nuclear power plant may cause obvious harm is still worth discussing. When we talk about the hazards of nuclear radiation, if we talk about toxicity away from the dose, we are playing hooliganism. After all, if we keep drinking water, large amounts of water can also cause water poisoning. People have enough knowledge about the hazards of high-dose radiation in a short time. From the explosion of nuclear weapons, people have already known for certain that short-term exposure to large doses can cause immediate death of organisms. For another example, in the Chernobyl nuclear power plant accident, a total of 225 victims were dealt with urgently at the scene, of which 4 died. Among the 143 people in need of treatment, 115 were sent to Moscow, of which 27 died (19 deaths from extensive beta particle skin burns, 6 deaths from bone marrow injury, and 2 deaths from gastrointestinal injury), that is, the number of deaths directly related to the accident was 31 people. However, little is known about the detailed studies on the harm to organisms caused by long-term exposure at low doses. For example, the sewage discharged from the Fukushima Nuclear Power Plant falls into this low-dose situation. The history of the human nuclear industry is only a few decades, and many reliable data and sufficient experimental data have not yet been accumulated. Especially under the conditions of small doses and dose rates, there is a lack of convincing data, and it is impossible to give low-dose radiation effects. Sufficient research on human hazards. Under the current circumstances, people’s guiding principle for nuclear radiation protection is to reduce unnecessary radiation doses as much as possible. According to the recommendations of the International Radiation Protection Committee, considering that the human living environment itself contains background radiation sources (such as cosmic rays, natural radioactivity in the environment), the safety standard for the annual dose equivalent of the general public is not more than 5mSv (Sv is The relevant unit of radiation dose, Sievolt), and the annual allowable whole body absorbed dose of nuclear radiation-related workers is 50mSv. Different sources of radiation and their effects on the human body Judging from the current standards, the harm of low-dose radiation to the human body is negligible and does not have a significant impact on human health. After all, the environment around us has background radiation, and radioactive materials are actually widely distributed in the environment, such as radon in the air and uranium in the soil. As long as the dose is not high and meets international safety standards. The above is a simple answer to the mechanism and process of radiation damage to human health. Back to the news, on the one hand, we must recognize the possible harm caused by the discharge of nuclear sewage, and on the other hand, we don’t have to panic too much. As long as the Japanese side can truthfully dilute and discharge nuclear sewage, the harm will be controllable. The radiation generated by the radioactive materials in these nuclear sewage is low enough after dilution, so there is no need to worry. As mentioned above, the specific impact and harm of nuclear sewage on the environment and humans is serious. It is necessary to estimate the amount of radioactive substances contained in nuclear sewage and the extent to which these substances can be diluted after entering the seawater. How many doses of radiation these radioactive materials may cause to the environment. However, because Japan’s Tepco has a history of handling accidents, people may generally lack trust in Japan’s handling. This may be the problem, and Japan’s emissions behavior may require joint supervision by the international community.

Thank you for the invitation of the big guys from People’s Daily Online. Although my major is not this, but my disaster medicine elective course is just a paper on how to save yourself in a nuclear disaster. Then I will say a few words here. First of all, you don’t have to worry about becoming a Cherno. The “living dead” in Bailey is because it is acute radiation sickness. In the TV series, the bone marrow radiation sickness is more serious. There are also intestinal radiation sickness and brain radiation sickness (here is too bloody, so I won’t include the picture). According to the paper of 307 Hospital. The survival rate of several acute radiation sicknesses is almost 0 (the bone marrow type has a very low chance of surviving, don’t think about the intestinal type and the brain type) (the Tokai Village critical nuclear accident in Japan is like this, only the lightest one survived, after all Only 2Gy) But this intensity of radioactivity will only be found near the core of Fukushima and near the radioactive material processing facilities. We don’t have to worry about it, but the long-term effects of radiation are what we need to pay attention to. It is the same as the DDT in this picture. The nuclear pollution that flows into the sea will also enter the body of relatively advanced predators with bio-enrichment, so don’t want to eat the fish. After all, the half-lives of Cs137 and Sr90 are 30 years and 28.5 years. You estimate that you will have to wait for this life to pass. When the radioactivity level drops to an appropriate level, the coastal fisheries and aquaculture industries of neighboring countries will be devastated. Sea salt will also be affected, and although a big guy reminded TEPCO in my answer to the previous article, it has already taken it out. The plan to melt down the core, but the current state will continue for a while, so the production of nuclear sewage will not stop for a short time, so the effect of bio-enrichment will continue forever. I don’t know much about ecology, but I don’t know much about radioactive substances. It can be used as a “fungicide” to make the earth “intestinal flora disorder” is also a serious problem. As for the solution, first of all, I have to affirm that TEPCO’s behavior in treating sewage is indeed very effective. Most of the radioactive materials are not low cost (after all, there are soluble radioactive salts everywhere…) Tritium is extremely difficult to remove. According to the national standard, the drinking water radiation should be less than 1Bq/L. It is 100Bq/L, add it here) And according to the data provided by @麻子麻子哈, the radioactive content of light tritium in the sewage of Fukushima is currently 860TBq converted to here (even if it is 2 million tons). Guess the light tritium What is the emission value of? 430000Bq/L Good guy, is this pollution controllable? I won’t say much about the rest. As for the solution, I can only save it! At least let these sewage go through a few half-lives, high-level solid waste, and deep-buried ordinary sewage filtration, and store it to the stage where there is no radioactivity. Let yourself try to confirm that there is no harm before discharging it into the sea without letting you have a Caesarean section. The powder is wrong you want. Use your own actions to clean up (attach the reference materials of the original thesis)

Some people think that after Japan’s nuclear sewage is discharged into the sea, seafood can no longer be eaten. This view is simply wrong. Don’t worry at all! Seafood can be eaten with confidence. As long as we don’t discharge nuclear sewage within dozens of kilometers around Fukushima, humans, animals, plants and seafood will not be affected. We can still drink and eat seafood with confidence. But the seafood around Fukushima doesn’t matter. However, it is important to know that the radioactive concentration in the marine organisms that have been contaminated by nuclear weapons is definitely higher than that in seawater, but the ocean itself contains radioactive substances. Radioactive elements in marine organisms have increased. In theory, since the normal discharge of Fukushima nuclear sewage will not increase the overall radioactive level in the seas far away from Fukushima, it will not cause radioactive effects on marine animals and plants. At the same time, everyone must know that Japan will not do anything to destroy mankind. After all, they have to develop. The Tokyo Electric Power Company said the truth before that nuclear sewage treatment is indeed qualified and it is discharged according to established standards. If you have a history, make sure you have it early and don’t relax your vigilance. If you can eat less seafood, you can wait for the research results of the marine department to come out.

The question we are most worried about is whether seafood can be eaten? Although the world’s water is connected, considering the direction of ocean currents and the pressure difference caused by the eastward flow of rivers into the sea in my country, some seafood products must be taken seriously in the future, and some can still be eaten. Hairtail, small yellow croaker, and pomfret are edible fish that are not from the deep sea, such as clams, flower shells, clams, mud Shellfish such as snails, scallops, and mussels live not far from the land. The pressure difference between the river and the east into the sea “washes” away the seawater with radiation pollution, and they are basically no problem. my country is a big importer of squid, and you should be cautious when you eat squid in the future, especially the squid from the west coast of the United States (the squid from Peru in South America should be better). Large lobsters should also be cautious. Salmon depends on the place of origin. Naturally, there is no problem with the salmon produced in Norway and the United Kingdom. If it is produced in Japan, the United States, or Canada, be cautious. Of course, I am not a professional. If the radioactivity of imported seafood exceeds the standard, the Chinese customs will naturally intercept it. The common seafood such as hairtail on the dinner table should not be greatly affected. Everyone should be cautious. When buying medium and high-end imported seafood, just pay attention to the place of origin, but you don’t have to panic and stock up a lot of goods. Although fortunately ocean currents do not come straight at us, and most of China’s rivers flow eastward into the sea, we cannot be alone. Radiation pollution does not only follow the ocean currents, it can also participate in the water cycle, turning into water vapor and turning into clouds and rain to fall on us. Japan does not discharge nuclear waste water because of technical problems that cannot be overcome—according to the normal treatment method, if nuclear waste water is placed in those big water tanks for 30 years, the radiation will be reduced to a safe level, and there will be no discharge at that time. questionable. The Tokyo Electric Power Company is unwilling to pay for renting land to enlarge water tanks, and this discharges nuclear waste water to harm the world. The Pacific Rim countries should take immediate action to rein in the precipice.

Greenpeace responded to the cover news: The Japanese government’s nuclear waste water discharged into the sea is “unjust”, fearing damage to human DNA Greenpeace responds to the cover news: The Japanese government’s nuclear waste water is discharged into the sea “unjust”, fearing damage to human DNA cover news video 341 According to a report from Japan’s NHK, the Japanese government held a relevant cabinet meeting on the morning of April 13 and officially decided to discharge nuclear sewage from the Fukushima Daiichi Nuclear Power Plant into the ocean, which is harmful to the marine environment. On April 12, the international environmental protection organization Greenpeace responded to the cover news interview via email, expressing its strong condemnation for the decision of the Japanese government’s cabinet to discharge more than 1.23 million tons of nuclear waste water from the Fukushima Daiichi Nuclear Power Plant into the Pacific Ocean. Leakage of Fukushima Nuclear Power Plant: 140 tons of nuclear waste water are produced every day. The 2011 “March 11th Earthquake” caused a power outage at the Fukushima Daiichi Nuclear Power Plant due to seawater infusion. Three of its four nuclear reactors exploded and melted down successively. , Causing a catastrophic nuclear leak. The continuous cooling of the core and the influx of rainwater and groundwater into the reactor facilities have produced a large amount of nuclear sewage, which is increasing. According to the report, Tokyo Electric Power Company is now adding 140 tons of “treated water” every day, and it is estimated that by September 2022, it will reach the upper limit of 1.37 million tons of storage tanks. Although the Japanese government has repeatedly stated that the concentration of discharged nuclear sewage meets international standards, and according to Tokyo Electric Power Company, this water should not be called “nuclear sewage” but should be called “treated water” because it has been treated and reduced The level of radioactivity, but the relevant data are still doubtful. These “nuclear sewage” reserves are huge. Once all of them are discharged to the sea, the possible impact on the marine environment and human safety still raises concerns. Greenpeace: The Japanese government is “unjust and outraged.” On April 12, the international environmental protection organization Greenpeace accepted the cover news interview by e-mail and sent a statement regarding the Japanese government’s decision to store the current in Fukushima No. A nuclear power plant’s decision to discharge more than 1.23 million tons of nuclear radiation wastewater into the Pacific Ocean strongly condemned it. Kazue Suzuki, director of the Climate and Energy Program of the Greenpeace Japan Office, believes that the Japanese government’s decision to ignore the ecological environment is completely unjust. “It not only disappoints the residents of Fukushima again, but also disappoints those living in the surrounding and Pacific Rim regions. Residents are exposed to the risk of nuclear radiation.” Suzuki said that although Japan has the technology and conditions to build more long-term storage tanks at the location of the Fukushima Daiichi Nuclear Power Plant and the surrounding unmanned areas, it will spread nuclear radiation to a certain extent. The risk is controlled to a minimum. “However, the government cabinet chose the most cost-effective way-dumping nuclear sewage into the Pacific Ocean.” Greenpeace told the cover news reporter that the fragile global marine ecological environment is already facing multiple challenges, Japan The government and TEPCO’s decision to go its own way is “outraging.” “The United Nations Convention on the Law of the Sea stipulates that’all countries have the obligation to protect and preserve the marine environment.’ If nuclear sewage is dumped into the Pacific Ocean, it will violate Japan’s responsibilities as a contracting party,” Greenpeace pointed out in the statement. Ten-year investigation: There is still radioactive pollution in the area. After the Fukushima nuclear spill occurred on March 14, 2011, the nuclear radiation investigation team of Greenpeace Japan Office was one of the first environmental organizations to arrive in Fukushima. Greenpeace has been one of the first environmental organizations to arrive in Fukushima in the past 10 years. Continue to conduct 32 surveys. On March 4, 2021, Greenpeace’s latest report “Fukushima 2011-2020 Ten-Year Nuclear Radiation Survey” recorded in detail the radiation values ​​of Iitate Village and Nange Town in Fukushima. The data showed that the local radiation removal work The effect is very limited, and nearly 85% of the officially designated “special decontamination area” still has radioactive contamination. On April 9, the Japanese government has basically decided to discharge the nuclear sewage from the Fukushima Daiichi Nuclear Power Plant into the sea, with the goal of starting discharge in two years. As soon as the news came out, it was protested and condemned by the Japanese people, environmental organizations and the international community. Decontamination technology is limited, and radioactive materials will damage human DNA. Greenpeace Japan Office senior nuclear power expert Shaun Burnie told the cover news reporter that Japan’s decision to discharge nuclear sewage into the Pacific Ocean will bear the brunt of the local fisheries in Fukushima. . At the same time, radioactive materials will diffuse through ocean currents. It is worth noting that in the past two years, fish with excessive radiation in the Fukushima waters have been repeatedly caught. In this regard, Sean Bernie said that “the situation is worrying.” As a neighboring country of Japan, how will China’s waters be affected? Sean Bernie analyzed that although the level of radioactive materials from Fukushima in the East China Sea will not be significant in the future compared with the coast of Japan, “but there is no reason for it to pollute any marine environment.” Although according to TEPCO The “water” that is about to be discharged into the sea should be called “treated water”. After treatment, the level of radioactivity is reduced. But Sean Bernie told the cover news that the water treatment technology (ALPA) of the Tokyo Electric Power Company’s multi-nuclides removal facility cannot remove radioactive tritium (extra-heavy water) or carbon 14 (C-14), nor can it completely remove other radioactive isotopes. , Such as strontium 90 (Sr-90), iodine 129 (I-129) and cobalt 16 (Co-16), all of which may cause damage to the DNA of humans and other organisms. “One of the main ways to receive these radioactive isotopes is to ingest contaminated marine food,” Sean Bernie explained. “These substances will accumulate in the marine food chain for a long time, even more than a thousand years, and may have passed through the food chain. Returning to human communities on land brings potential health risks.” Sean Bernie further pointed out that when people are exposed to nuclear radiation, collective radiation doses can have corresponding health effects, and carbon 14 (C-14) With a half-life of 5730 years, it will become the main element of human collective radiation dose. “It will be incorporated into proteins, nucleic acids, especially DNA and other cellular components, and the resulting DNA damage may lead to cell death or potential genetic mutations.”

I originally predicted that Japan would secretly discharge nuclear waste water, and then find temporary workers or another natural disaster. Unexpectedly, I didn’t expect that the Japanese didn’t even bother to look for temporary workers, so they went directly to the government. I still think of the Japanese too well. 1. It is too late to throw a hydrogen bomb to accelerate the decay of nuclear waste. When Japan really discharges the water into the sea, there is really no room for recovery. 2. But from another perspective, this may be a bargaining chip for the Japanese to coerce the world with technology, capital and manpower to help Japan solve problems.
