fukushima radiation map 2020

Radioactive caesium in soil and fallen leaves in forests in his opinion would be easily absorbed by mushrooms and edible plants. [352] A rush for iodine antiseptic solution appeared in Malaysia. 27 Nov 2020 00:00 - 27 Dec 2020 00:00 Year (10 sec loading time) 6 Month (10 sec loading time) "[66] Iodine-131 has a half-life of 8 days while caesium-137 has a half-life of over 30 years. [121] In particular, the Asahi reported that radiation levels of 300 mSv/h were detected at least twice on 13 March, but that "the workers who were trying to bring the disaster under control at the plant were not informed of the levels. But director Makoto Akashi of the National Institute of Radiological Sciences said, that although those test results should be verified, this still proved the possibility of internal exposure in the children of Fukushima, but that the internal exposure would not increase, when all food was tested for radioactivity before consumption. In more and more places contaminated meat was found. [184][185], Periodic overall reports of the situation in Japan are provided by the United States Department of Energy. It did set a new record: containing 740,000 becquerels radioactive caesium per kilogram, 7,400 times the Japanese limit deemed safe for human consumption. Wind shift to north takes place Tuesday midnight. As of July 18th, 2011", https://web.archive.org/web/20110402051303/http://english.kyodonews.jp/news/2011/03/82005.html, https://abcnews.go.com/International/japan-nuclear-crisis-worker-speaks-radiation-dangers/story?id=13271759Japan, Contaminated nuke plant workers going back on job as safety regs go by wayside, "TEPCO concealed radiation data before explosion at No. [18], A June 2012 Stanford University study estimated, using a linear no-threshold model, that the radioactivity release from the Fukushima Daiichi nuclear plant could cause 130 deaths from cancer globally (the lower bound for the estimate being 15 and the upper bound 1100) and 199 cancer cases in total (the lower bound being 24 and the upper bound 1800), most of which are estimated to occur in Japan. [217] Scientists preparing this map, as well as earlier maps, targeted a 20 mSv/a dosage target for evacuation. No caesium-134 or iodine-131 was detected. A relatively high-radiation-level region which is located in the west boundary of Fukushima Prefecture is well known as a granite field. These were 14 to 15 times higher than the limit set by NISA. [28][29][30], In 2013 (two years after the incident), the World Health Organization indicated that the residents of the area who were evacuated were exposed to little radiation that radiation induced health impacts are likely to be below detectable levels. Fukushima nuclear disaster: Lethal levels of radiation detected in leak seven years after plant meltdown in Japan. Indeed, thats what the members of the local and central government, as wel… The contaminated stone was found in some 49 houses and apartments. [217] The government's 20 mSv/a target led to the resignation of Toshiso Kosako, Special Adviser on radiation safety issues to Japanese Prime Minister Naoto Kan, who stated "I cannot allow this as a scholar", and argued that the target is too high, especially for children; he also criticized the increased limit for plant workers. [140] TEPCO later retracted its report, stating that the measurements were inaccurate and attributed the error to comparing the isotope responsible, iodine-134, to normal levels of another isotope. At 50 centimeters above the ground the reading was 1.7 microsieverts per hour. [120] Confidential documents acquired by the Japanese Asahi newspaper suggest that TEPCO hid high levels of radioactive contamination from employees in the days following the incident. [4][57][60] Strategies that aim to reduce the incidence of the negative cultural stigma on mental health disorders in Japan should be implemented. [42] The maps revealed radiation levels of more than 125 microsieverts per hour at 25 kilometers northwest of the plant, which means that people in these areas were exposed to the annual permissible dose within eight hours. Plutonium-239 is long-lived and potentially toxic with a half-life of 24,000 years. On 17 March IAEA radiation monitoring over 47 cities showed that levels of radiation in Tokyo had not risen. The meat of some 132 cows was sold to at least 36 of the 47 prefectures of Japan. [216] Similar data was used to establish a map that would calculate the amount of radiation a person would be exposed to if a person were to stay outdoors for eight hours per day through 11 March 2012. Additional basement and trench-area measurements indicated 60 mSv/h in unit 1, "over 1000" mSv/h[138] in unit 2, and 750 mSv/h in unit 3. [76] On 23 April, NSC updated this number to 0.14 TBq per hour of caesium-137 on 5 April, but did not recalculate the entire release estimate. All rice of the fields nearby was stored and none of this rice had been sold to the market. [53], Findings from the Chernobyl disaster indicated the need for rigorous resource allocation, and research findings from Chernobyl were utilized in the Fukushima nuclear power plant disaster response. The concentration was 0.14 becquerel per kilogram and none was discovered yesterday, which compares with 0.21 becquerel on 22 April, according to the Tokyo Metropolitan Institute of Public Health. This was the ministry's first discovery of radioactive substances beyond legal limits since the tests of food stuffs started in August. [274], Japan banned Fukushima beef. Animal feed and meat cuts had not been checked for radioactivity previously. Although all other tests of beef cattle found far lower levels of radioactivity than the government standard, prices of beef from Shimane plummeted and wholesalers avoided all cattle from the prefecture. Their home was situated near a highly radioactive spot, and after this find the family moved out of Fukushima Prefecture. In 2011 at this place the fish measured about 50 becquerels per kilogram, and the fishing season was opened as usual. The exact dose rate remains unknown as the technicians fled the place after their first measurement went off-scale. According to the ministry, clouds moving southwards apparently caught large amounts of iodine-131 that were emitted at the time. [37], In the general population, no increase is expected in the frequency of [58] Ethical considerations need to be taken regarding the impact on mental health versus the costs of allowing low amounts of exposure. Local governments were asked to carry out simple decontamination works, such as clearing mud from ditches if necessary. Up to 44 becquerels per kilogram of strontium-90 were detected, which has a half-life of 29 years. [200], In August 2012, Japanese academic researchers announced that 10,000 people living near the plant in Minamisoma City at the time of the accident had been exposed to well less than 1 millisievert of radiation. The mushrooms were grown on beds made of woodchips mixed with other nutrients. Contamination between 30,000 and 100,000 becquerels per square meter was found in Ichinoseki and Oshu (prefecture Iwate), in Saku, Karuizawa and Sakuho (prefecture Nagano, in Tabayama (prefecture Yamanashi) and elsewhere. Further studies to determine the effect on the food-chain and fish would be needed. It has been thus confirmed that radioactive materials in the ocean are moving and spreading not just by ocean currents but by various other means. Can 2020 Summer Olympics help Fukushima rebound from nuclear disaster? "The government has also acknowledged that the problem could be wider than just Fukushima. Up to 30.8 becquerels per kilogram was found in Meiji Step milk powder. Starting from the second week of August all cattle were tested. [254], The health ministry published in August 2012, that caesium levels in tea made from "yacon" leaves and in samples of Japanese tea "shot through the ceiling" this year. [254], In April 2012 radioactive caesium concentrations of 110 becquerels per kilogram were found in silver crucian carp fish caught in the Tone River north of Tokyo, some 180 kilometers away from the Fukushima Daiichi Plant. [94] This emission of radioactivity into the sea represents the most important individual emission of artificial radioactivity into the sea ever observed. The melted material was not expected to breach one of the lower containers, causing a serious radioactivity release. Radiation levels of 0.8 mSv per hour were found, almost as high as the radiation levels outside the homes. However, the levels were below the safety limits for tap water consumption by infants. [229][230], On 12 November the Japanese government published a contamination map compiled by helicopter. According to this report, in several parts of Fukushima Prefecture – including Futaba and Okuma – the air would remain dangerously radioactive at levels above 50 millisieverts a year. The data is collected by aircraft equipped with radiation monitoring equipment. [122] As of 19 July 2011, 33 cases of heat stroke had been recorded. [213], On 31 October 2011 a scientist from the Worcester Polytechnic Institute, Marco Kaltofen, presented his findings on the releases of radioactive isotopes from the Fukushima accidents at the annual meeting of the American Public Health Association (APHA). This corresponds to less than a chest X-ray to 3 chest X-rays. The map contains the caesium concentrations and radiation levels caused by the airborne radioactivity from the Fukushima nuclear reactor. Due to the low baseline rates of thyroid cancer, even a large relative increase represents a small absolute increase in risks. In September and October two water samples were taken, measuring 1,103 becquerels per liter and 1,054 becquerels per liter respectively. [151] The water was measured to have 3 MBq/cm3 of Cs-137 and 13 MBq/cm3 of I-131: TEPCO characterized this level of contamination as "extremely high.
