Harm of nuclear leakage in Japan earthquake
65,438+200,000 people received nuclear radiation inspection.

During the inspection, 22 people were exposed to nuclear radiation.

According to CCTV reports, Fukushima has confirmed that the number of people exposed to nuclear radiation has risen to 22. The Japanese government has increased the evacuation scope of the Fukushima Daiichi nuclear power plant and the Fukushima II nuclear power plant from 10 km in Fiona Fang to 20 km in Fiona Fang. 65,438+020,000 asylum seekers were examined for all nuclear radiation conditions.

The inspection team entered the bomb shelter for testing.

China inspection team entered the bomb shelter and began the test.

The Fukushima prefectural government announced on June 5438+03 that 19 people evacuated from Fiona Fang, the first nuclear power plant of Tokyo Electric Power Company, suffered from nuclear radiation. Together with the three people who have been confirmed and rescued before, the number of people who have been confirmed to have suffered from nuclear radiation has risen to 22.

Although the official figure is 22, the media believe that there may be more than 190 people with similar nuclear radiation symptoms.

The Fukushima prefectural government announced in late June of 5438+03 that it had decided to inspect all120,000 asylum seekers in 533 shelters in the county. The inspection team consisting of 80 people will start the nuclear radiation inspection of the shelters in the county on June 5438+05. Three places, including Koriyama Gymnasium, were set up as inspection centers, and the inspection began with residents living in nuclear power plants. Fukushima prefectural medical university said that it will provide medical support for patients with nuclear radiation found.

CCTV reported that the Fukushima prefectural government announced on 13 that 19 people evacuated from the Fukushima Daiichi nuclear power plant in Fiona Fang were exposed to nuclear radiation.

Medical staff are "infected"

Fukushima nuclear leak, 19 medical staff was polluted, and the nuclear leak polluted Tokyo.

Fukushima Shuangye Health and Welfare Hospital reported that 19 medical staff had been diagnosed with nuclear radiation, and they began to check and care for citizens suffering from nuclear radiation last night.

The Fire Department of the Ministry of Internal Affairs and Communications also announced that 15 inpatients and ambulances in hospitals within the range of Fiona Fang 10 km of the nuclear power plant were contaminated by radioactive substances. Chief Cabinet Secretary Yukio Edano said that "it is unlikely to produce dangerous and healthy radiation".

In the Fukushima nuclear accident, 19 medical staff have been exposed to nuclear radiation, and their health status has been further reduced.

Power shortage takes turns to cut off power everywhere.

During the earthquake and tsunami, Fukushima shut down several nuclear reactors.

Due to the closure of several nuclear reactors after the earthquake and tsunami, there may be a power shortage. According to Kyodo News, Japanese Prime Minister Naoto Kan said at the press conference on June 38+03 that "Tokyo Electric Power Company has been approved to implement the planned (alternate) power outage from June 38+04" to cope with the power shortage after the earthquake in Japan.

The planned power outage will be implemented in various regions in turn.

Endangering China.

The radioactive elements in parts of the western Pacific Ocean are 300 times higher than those in China. The preliminary results of radioactive monitoring of marine environment in the western Pacific recently published on the website of the State Oceanic Administration have attracted the attention of all parties. The Department of Environmental Protection of the State Oceanic Administration said in a written reply to the reporter of Science and Technology Daily on August 2, 201/2008 that the monitoring results showed that the polluted high seas far exceeded the influence scope announced by Japan, and the possibility of nuclear pollutants entering the waters under our jurisdiction was not ruled out. "Because this monitoring voyage has collected a large number of samples, it will take some time for laboratory analysis and testing. In order to announce the monitoring results to the public in a timely manner, our bureau adopted the method of batch detection and batch announcement. " It was replied that the western Pacific Ocean radioactivity monitoring area is located in the high seas of 252,000 square kilometers east of Fukushima, Japan, and the results of the first batch of seawater samples at some stations were announced this time.

The results showed that the radionuclides cesium-137, strontium -90 and cesium-134, which could not be detected in seawater under normal conditions, were all detected in the samples. Among them, the highest contents of cesium-137 and strontium -90 are 300 times and 10 times of the background range of China's sea areas, respectively, and the highest contents of cesium-137 and cesium-134 are higher than China's seawater quality standards.

"The monitoring results show that the western Pacific Ocean east and southeast of Japan has been significantly affected by the Fukushima nuclear accident." The reply said, "It is certain that marine life in the monitoring area will be polluted to varying degrees. However, the degree of pollution in different areas of the monitoring area is different, and the enrichment of radionuclides by different marine organisms is also different. " The reply said that because the half-life of cesium-137 and strontium -90 is about 30 years, the impact is lasting, especially the long-term impact of radioactive substances on marine organisms and marine ecosystems and even human health will not be ignored.

Since the nuclear accident in Fukushima, Japan, on March 1 1, the State Oceanic Administration has been organizing radioactive emergency tracking and monitoring to deal with the accident. According to the monitoring results, the Fukushima nuclear accident has not yet affected China's waters. However, this reply shows that according to previous studies, the ocean circulation in the sea area east of Fukushima, Japan is complex, and the main ocean currents are Kuroshio and pro-current. The large-scale serpentine bending of the Kuroshio extension zone and the mesoscale vortices on the north and south sides are the reasons for the relatively active power in this sea area. Therefore, Fukushima nuclear pollutants may have multiple moving paths after entering the sea. The main moving path is that the Kuroshio along the east coast of Japan extends eastward to the waters near Tokyo and enters the North Pacific Ocean. However, some data also show that the water body in the tide-loving system can also move southward through mesoscale vortex and Kuroshio extension. The reply said: "The possibility of nuclear pollutants entering the waters under our jurisdiction cannot be ruled out."

According to data released by Japan in May, the coastal waters of Fukushima, Japan were contaminated by radioactivity. However, the monitoring results of the State Oceanic Administration show that 252,000 square kilometers of high seas within 800 kilometers east of Fukushima, Japan, have been obviously contaminated by radioactivity, which is far greater than the scope of influence announced by Japan.

The reply said that from the preliminary analysis results, the voyage of marine radioactivity monitoring in the western Pacific is very necessary and timely. This will not only provide valuable information for our country to understand and master the marine radioactive pollution in the waters east of Fukushima, Japan, but also provide important data support for analyzing and evaluating the possible impact of Fukushima nuclear accident on the waters under our jurisdiction, thus protecting China's marine environmental safety and public health. However, in order to accurately judge and predict the migration of nuclear pollutants and its impact on the marine environment and marine food safety, long-term follow-up monitoring and evaluation are needed.

The reply said that in order to further understand, master and evaluate the impact of the Fukushima nuclear accident on the western Pacific Ocean and the sea areas under the jurisdiction of China, China needs to continue to carry out radioactive monitoring in the western Pacific Ocean and the sea areas under the jurisdiction of China, with emphasis on marine biological radioactivity monitoring and radioactive sewage drift path prediction.

In addition, after the test results of the first batch of seawater samples came out, the follow-up test and data analysis and processing of seawater, marine life and marine atmospheric aerosol samples are still in progress. The Ministry of Environmental Protection said that the monitoring results of marine biological radioactivity will be released in time according to the progress of sample detection and analysis.
