Present situation of nuclear radiation areas in Japan

1, Fukushima, Japan, one of the top ten nuclear pollution areas in the world, nuclear radiation leaked into the restricted area. 2. Is it nuclear radiation in Haroubi, Yuxian? 3. The influence range of nuclear radiation in Japan. 4. The Fukushima nuclear food imported from Taiwan Province detected radiation, which was the first case after opening up. Can Japanese food still be eaten? 5. Is there still nuclear radiation in Nagasaki and Hiroshima? Fukushima, Japan, the world's top ten nuclear pollution areas, nuclear radiation leakage into the restricted area.

Environmental pollution has become one of the most important topics in the world today, especially nuclear pollution, which is not only harmful, but also has a long-term, wide-ranging and uncontrollable impact. Seeing this, do you want to follow me to see the top ten polluted areas in the world, which are also the top ten most polluted places in the world, but let's learn about it now.

10. USA: hanford

Hanford base is a comprehensive facility that has been mostly retired, producing plutonium for most weapons in the US nuclear arsenal, and now it is one of the largest polluted areas in the United States. Hanford site was built in 1943, which is an important part of American atomic bomb project. Mainly used in experiments. The first nuclear bomb dropped on Nagasaki was tested here. However, after the end of the cold war, the site was demolished, but the city left behind high-level radioactive waste-about 53 million gallons of radioactive waste and 25 million cubic feet of solid radioactive waste, which were stored in the 177 storage tank.

9. Italy: Mediterranean

For years, the Italian mafia has been dumping radioactive waste into the sea. They also put radioactive waste on ships in different countries and continue to profit from illegal dumping of garbage. According to international media reports, 1994, some Italian ships threw radioactive waste into the Mediterranean Sea. But this move undoubtedly did not bring great pollution and damage to this sea area.

8. Somalia: Somali coast

According to some reports, Italian mafia members have been dumping radioactive waste off the coast of Somalia for 10 years. Therefore, the coast of Somalia is not caused by the country itself, but by the secondary pollutants of nuclear waste transferred from Italy.

7. Russia: Merhachi

The Kelche Teng nuclear accident in Russia is one of the most serious radioactive pollution accidents at the Mehats nuclear power plant, and it is also the third largest nuclear disaster after the Fukushima Daiichi nuclear power plant and the Chernobyl disaster. About 65,438+000 tons of radioactive waste was released due to the explosion, and these wastes were dumped into Lake Karakai and its surrounding areas, causing a lot of water pollution. Now, due to huge nuclear pollution, the area is basically abandoned.

6. Britain: Sellafield

Selafield, located near Haibei Village on the coast of the Irish Sea, was originally a nuclear facility for producing plutonium. However, the safety performance of this nuclear facility is not high, which leads to nuclear leakage, making this place a serious nuclear pollution area, ranking sixth on this list.

5. Russia: Siberia

Siberia, 3000 kilometers from Moscow, has been abandoned, mainly because the stratum was used for nuclear tests. However, the abandoned nuclear here was left there, causing nuclear pollution in this place. These wastes are about 6.5438+0.25 million tons, so you can imagine how serious the nuclear pollution is in this area.

4. Kazakhstan: Semipalatinsk

Semipalatinsk test site, also known as polygon, is one of the main sites for nuclear weapons testing in the Soviet Union. Seeing this is also caused by Russia. From 1949 to 1989, about 456 nuclear tests were conducted in this area, and it was not closed until 199 1 These tests also led to a large number of nuclear leaks, which seriously endangered the residents there. Now this area has been abandoned.

3. Kyrgyzstan: Marusu

Marusu, a small uranium mine town, now ranks third on this list. The main pollution in this area comes from radioactive pollution of raw materials during mining, not any nuclear waste. This uranium mine site left about 6.5438+0.96 million cubic meters of uranium waste, and it is conceivable how strong the radioactive material is.

2. Ukraine: Chernobyl

The Chernobyl nuclear accident is a world-famous nuclear pollution, ranking second on this list, which occurred on1April 26, 986. The explosion of the facility caused a large amount of radioactive materials to be released into the earth's atmosphere and spread to Europe and the Soviet Union. Due to this huge disaster, nearly 6 million people are at risk of exposure, and now the site has been completely abandoned.

1. Japan: Fukushima

The earthquake and tsunami of 20 1 1 are the chief culprits of this nuclear power plant disaster. Eventually, three nuclear reactors melted down and a large amount of radioactive materials were released to the surrounding areas. It is considered as one of the biggest nuclear accidents after 1986 Chernobyl accident, and continues to pose a great threat to the environment and human health all over the world.

_ Is Haruki City in Yuxian County a nuclear radiation?

At present, Fukushima Prefecture has the greatest influence on nuclear radiation in Japan, followed by Chiba Prefecture, _ Muxian Prefecture, Ibaraki Prefecture, Miyagi Prefecture, Yamagata Prefecture, Niigata Prefecture, Nagano Prefecture, Yamanashi Prefecture, saitama, Tokyo and Ma Prefecture.

The influence range of nuclear radiation in Japan

Because it takes a long time to deal with a nuclear accident, nuclear radiation in the relevant areas may exist for a long time.

At present, the radiation from 80 kilometers south of Fukushima nuclear power plant to the northeast of Ibaraki Prefecture and from the southwest to the northeast of _ Mu Prefecture is slightly higher, ranging from 0.2 to 0.5 microsieverts per hour.

According to the Japanese news agency 2011May 06, the joint emergency command center of the Japanese government and Tokyo Electric Power Company released a map of radiation pollution near the surface drawn by the Japanese Ministry of Education, Culture, Sports, Science and Technology and the US Department of Energy based on aircraft monitoring data on the 6th. The map shows that the cumulative radiation of 1 year may exceed 100 mSv in a large area 30 kilometers northwest of Fukushima Daiichi nuclear power plant.

The map shows the radiation on April 29th. In some areas of Langjiang Town and Dining Village in Fukushima Prefecture, 30 kilometers away from Fukushima Daiichi Nuclear Power Plant, the hourly radiation amount reaches 19 mSv, and the cumulative radiation amount of 1 year may exceed 100 mSv. The Ministry of Education, Culture, Sports, Science and Technology of Japan said: "Because wind and rain can gradually reduce radioactive substances, the possibility of actually exceeding 100 mSv is very small."

The cumulative radiation in parts of Nishimma, Kawasaki-CHO and Ida, which are 30 kilometers away from the Fukushima Daiichi nuclear power plant, may also exceed 20 millisieverts in 1 year. On April 26th, the Joint Emergency Command Center released the radiation map based on the measured values. This map shows almost the same value.

The Joint Emergency Command Center also published a map showing the data of radioactive materials on the surface of soil, and it was detected that the area containing 3 million to 30 million radioactive cesium per square meter in becquerel extended to the northwest. The report pointed out that Japan has not yet formulated pollution standards for soil radioactive materials.

The Ministry of Education, Culture, Sports, Science and Technology of Japan announced the radiation distribution map 80km away from the Fukushima Daiichi nuclear power plant, which was jointly drawn with the US Department of Energy on June 6th, 201/. (* * * Children's Society

BEIJING, June 16 (Xinhua) According to Kyodo News, the Ministry of Education, Culture, Sports, Science and Technology of Japan announced the radiation distribution map of the Fukushima Daiichi nuclear power plant 120 km in some areas from June 80 to100 km. The figure shows that the radiation in the south and southwest of the nuclear power plant is relatively high. Japan's Ministry of Education said: "The radiation value is very low, so it can be considered that there is no impact on health."

The investigation was conducted jointly with the US Department of Energy from May 18 to May 26, and the helicopter detected the radiation at a distance of 1 m from the ground.

80 kilometers south of the nuclear power plant to the northeast of Ibaraki Prefecture and southwest to northeast of _ Mu Prefecture have slightly higher radiation, ranging from 0.2 to 0.5 microsieverts per hour.

March 12 dongfang. com: on June 12, Cheng Yonghua, a member of the Chinese people's political consultative conference and Japanese ambassador to Japan, said in an interview with this reporter that six years have passed since the accident at Fukushima nuclear power plant, "but I personally feel that the water pollution problem has not been completely controlled, which deserves our attention. Japanese tourists who travel to China can learn this information from the Internet to arrange their own itinerary. "

/kloc-On the afternoon of 0/2, Ambassador Cheng Yonghua, who returned to China to attend the Fifth Session of the 12th Chinese People's Political Consultative Conference, told International Online that the relevant reminder issued by the Embassy in Japan a month ago was very clear and suggested that overseas Chinese and Japanese citizens in Japan should make good travel plans.

The reporter asked, "Japanese tourists visiting China are unlikely to be affected by nuclear radiation if they don't go to three northern counties such as Fukushima?" Ambassador Cheng said that this issue is really complicated. 3 1 1 The earthquake killed about 20,000 people. At present, about120,000 people are still unable to go home and are still in a state of refuge. Because of the earthquake, tsunami and nuclear leakage, this major disaster has many lessons. At the same time, Japan has made great efforts to overcome difficulties and disasters.

Cheng Yonghua said, but the specific scope of the Fukushima nuclear accident, the Japanese government first said that the surrounding 20 kilometers, and then expanded to 30 kilometers. "But we didn't release it to the public, and there is still a data worthy of reference. The US Embassy in Japan (at that time, it issued a notice requesting evacuation measures for 80 kilometers around. "

According to Cheng Yonghua, after several years of continuous cleaning, including measures for land and buildings, some residents have gradually returned to their original places of residence. However, in the area around the Fukushima nuclear power plant, there are still some people who cannot return home.

At present, "in the reactor of the Fukushima Daiichi nuclear power plant, the nuclear fuel rods are already in a molten state, so it is very dangerous, and the robots sent in are also' sacrificed' inside." Cheng Yonghua said, so the radiation value inside the reactor is very high. At present, the method of cooling with cold water is primitive, and the treatment of polluted water is worrying.

Cheng Yonghua said that nuclear radiation has polluted the groundwater nearby, and the polluted water has also polluted the seawater. "Japan is also trying to solve these problems, but I personally feel that the water pollution problem has not been completely controlled, which deserves attention."

On February 12, the Japanese Embassy in Japan issued a reminder about Fukushima nuclear radiation, saying that recently, the Japanese media repeatedly reported that the radiation in the containment of Unit 2 of the Fukushima Daiichi nuclear power plant reached a high value, which caused my overseas Chinese in China and Japanese tourists visiting Japan to worry. A few days ago, a spokesman for the Ministry of Foreign Affairs said: China has been paying close attention to the impact of the Fukushima nuclear accident in Japan and has repeatedly asked the Japanese government to do a good job in the follow-up treatment of the accident. I hope that the Japanese government can make a responsible explanation on how to take effective measures to effectively eliminate the impact of nuclear accidents. This is not only responsible to Japanese nationals, but also to the people of neighboring countries and the international community. The Ministry of Foreign Affairs has issued relevant safety reminders.

The reminder also said that on March 2011year 10, an earthquake measuring 9 on the Richter scale occurred in the waters near Miyagi Prefecture, Japan, which triggered a major nuclear accident at the Fukushima Daiichi nuclear power plant. The Japanese government requires residents within 30 kilometers of Fiona Fang to take corresponding measures to avoid risks. Up to now, the Japanese government has designated a certain area around the Fukushima Daiichi nuclear power plant as an evacuation indication area. It takes a long time to deal with a nuclear accident, and nuclear radiation in the relevant areas may exist for a long time. It is suggested that overseas Chinese in China and Japanese citizens in Japan make good travel plans.

Radiation was detected in Fukushima nuclear food imported from Taiwan Province, which was the first case after opening up. Can Japanese food still be eaten?

Radiation was detected from Fukushima nuclear food imported from Taiwan Province, which was the first case after opening up. At present, Japanese food is certainly edible, but we must be careful and eat less.

1. Radiation was detected in Fukushima nuclear food imported from Taiwan Province, which was the first case after opening.

According to current news reports, radiation has been detected in Fukushima food imported from Taiwan Province Province, which is the first case since they opened up the import of Japanese seafood. The products that were found to be contaminated by nuclear were really unexpected, which also triggered a huge discussion on the Internet, but more people are thinking about whether Japanese food can still be eaten after opening up. After all, it is quite rare to detect radioactive substances in modern society, which means that the risk of Japanese food is really high.

Second, Japanese food can be eaten: but eat less and be careful.

According to the current situation, it cannot be said that such a situation in a certain place means that corresponding contaminated products will appear in all places. However, eat less and be careful. After all, if we eat something like this carelessly, it may not only affect our physical condition, but also cause our offspring to fall into the root cause when they reproduce. This is the serious consequence of nuclear pollution that we must be aware of. This kind of nuclear pollution has a great influence on food. After all, nuclear pollution will change a person's physiological structure, which is quite terrible.

Third, Japan's current nuclear radiation impact may be more serious than we thought.

No matter whether the floating island imported from Taiwan Province Province has the test results of radioactive substances, we are well aware of the Japanese nuclear radiation leakage. Long ago, Japan adopted the idea of discharging nuclear waste water into the Pacific Ocean. No one knows whether Japan has secretly discharged these wastewater. This kind of wastewater has a much more serious impact on the fishery in the waters around Fukushima than we thought, so we just said, eat less Japanese food and be careful.

Is there still nuclear radiation in Nagasaki and Hiroshima, Japan?

"Today's Hiroshima can't say that there is no nuclear radiation at all, but at least it meets the basic conditions for human survival.

According to the data released by the United Nations Scientific Committee on the Effects of Atomic Radiation, the radiation value in Hiroshima is now about 0.3 microsieverts per hour, which can reach 2.64 microsieverts per year (the natural radiation acceptable to ordinary people is 2.3 microsieverts per year). In other words, the radiation value in Hiroshima is equivalent to the world average.

This is the first time in human history that nuclear weapons have been used in actual combat, and it also makes human beings see the unprecedented lethality and destructive power of nuclear weapons for the first time, and truly feel the terror of nuclear weapons.

A large amount of nuclear radiation will be produced after the explosion of nuclear weapons. The "little boy" uses uranium -235 radioisotope with a half-life of 700 million years.
