The find was done by a private agency that conducted the test upon the request of a resident. [12][145] Inside primary containment, levels are much higher. [216] The map showed that a belt of contamination, with radioactivity from 3 to 14.7 MBq caesium-137 per square meter, spread to the northwest of the nuclear plant. [119] Others reports suggest that contract workers are given more dangerous work than TEPCO employees. [309] The results of the tests will be mailed to the children within a month. [363] Daily monitoring and some precautionary measures were recommended for Yokosuka and Atsugi bases, such as limiting outdoor activities and securing external ventilation systems. Six fishery cooperatives and 10 towns along the river were asked to stop all shipments of fish caught in the river. Because of the short half-life of 8 days only 400 locations were still positive. Persons exposed to releases of I-131 from any source have a higher risk for developing thyroid cancer or thyroid disease, or both. The farmers were asked to stop all shipments and to call back the mushrooms already on the market. [96] At the end of October 2012 TEPCO admitted that it could not exclude radioactivity releases into the ocean, although the radiation levels were stabilised. [183], In February 2014, NHK reported that TEPCO was reviewing its radioactivity data, after finding much higher levels of radioactivity than was reported earlier. [305][306], Mid November 2011 radioactive caesium was found in milk-powder for baby-food produced by the food company Meiji Co. Fukushima Prefectural Government. November 2, 2020 … [95], A year after the disaster, in April 2012, sea fish caught near the Fukushima power plant still contain as much radioactive 134Cs and 137Cs compared to fish caught in the days after the disaster. All of the radiation had dissipated completely within one month of detection. The minister said that the government should try to buy uncontaminated straw and hay in other parts of the country and offer this to the farmers in the affected areas. [364] As a precaution, the Washington was pulled out of its Yokosuka port later in the week. [104][105] This level is below the 500 mSv/year considered acceptable for emergency work by the World Health Organization. Iodine-131 was also found in the same areas, and most likely the tellurium was deposited at the same time as the iodine. Pre-harvest tests were carried out in nine prefectures in the regions of Tohoku and Kanto. [291], On 7 February 2012 noodles contaminated with radioactive caesium (258 becquerels of caesium per kilogram) were found in a restaurant in Okinawa. A map of the Fukushima radiation spread across the Pacific ocean roughly matching up with ocean currents. No deposition could be determined in 28 of them until 25 March[101] The highest value obtained was in Ibaraki (480 Bq/m2 on 25 March) and Yamagata (750 Bq/m2 on 26 March) for iodine-13. Radioactive materials were detected in 94 locations, or 4.3 percent of the total. [4] Furthermore, researchers and policymakers should continue to monitor for long-term mental effects as they may not be present right away.[4][57]. [214], Tests concluded between 10 and 20 April revealed radioactive caesium in amounts of 2.0 and 3.2 kBq/kg in soil from the Tokyo districts of Chiyoda and Koto, respectively. But in January 2012 due to human activities at the plant, the emissions rose again up to 19 thousand becquerel. [58] Tough restrictions were left in place because the public generally did not have a clear idea of the risks from radiation exposure, and implementing policy changes to reflect less restrictive, but low-risk, levels of radiation received push-back in Japan. [267] The same day the Japanese ministry of agriculture urged farmers and merchants to renounce the use and sale of compost made of manure from cows that may have been fed the contaminated straw. This may have been in an area directly affected by a cloud of radioactive materials from the plants. [6], While there were no deaths caused by radiation exposure, approximately 18,500 people died due to the earthquake and tsunami. [308], On 9 October a survey started in the prefecture Fukushima: ultrasonic examinations were done of the thyroid glands of all 360,000 children between 0 and 18 years of age. [citation needed], According to a June 2011 report of the International Atomic Energy Agency (IAEA), at that time no confirmed long-term health effects to any person had been reported as a result of radiation exposure from the nuclear accident. [294], In the city of Yokohama in March and October food was served to 800 people with dried shiitake-mushrooms that came from a farm near this town at a distance of 250 kilometer from Fukushima. [322] The minister of Industry Yukio Edano did instruct TEPCO to pay compensation for the economical damages. Fukushima Radiation Map | mail | 日本語 | IIDj, is collecting available measurements since March 26 of 2011 to provide a consistent and comprehensive Japan Radiation Map. [38] No significant increase in heritable effects has been found in studies of the children of the survivors of the atomic bombings of Hiroshima and Nagasaki or in the offspring of cancer survivors treated with radiotherapy, which indicates that moderate acute radiation exposures have little impact [37], In the general population, no increase is expected in the frequency of [56][60] About a quarter of the women who were pregnant at the time of the disaster experienced symptoms of depression, and though the proportion of concerned expectant mothers decreased over time, counselling services were still provided in the years following due to the number of women concerned about the potential health effects from the event. [63] In May 2012, TEPCO reported that at least 900 PBq had been released "into the atmosphere in March last year [2011] alone"[64][65] up from previous estimates of 360–370 PBq total.
