On 23 March – after the Americans – Japan released its own fallout maps, compiled by Japanese authorities from measurements and predictions from the computer simulations of SPEEDI. On 19 June 2012 Minister of Science Hirofumi Hirano said that Japan would review the decision of the Science Ministry and the Nuclear-Safety Agency in 2011 to ...
Radiation hotspot in Kashiwa, February 2012 [66] Map of contaminated areas around the plant (22 March – 3 April 2011) [67] In response to the station blackout during the initial hours of the accident and the ongoing uncertainty regarding the cooling status of units 1 and 2, a 2 km radius evacuation of 1,900 residents was ordered at 20:50. [68]
The Yomiuri Shinbun calculated radiation doses based on data from the Fukushima prefectural government and found they corresponded with the forecasts. [4] SPEEDI figured in controversy surrounding the Japanese government's use of the data and its failure to use it in planning evacuation routes.
The first of the typhoons of the season is due to strike the area, while Japan states radiation levels at the seabed are several hundreds of times above normal levels off the coast of Fukushima. "The Science Ministry announced late on Friday highly radioactive materials were detected in a 300-km north-south stretch from Kesennuma in Miyagi ...
[35] [38] As of 21 October 2011, the largest study on Fukushima fallout concludes that Fukushima was "the largest radioactive noble gas release in history not related to nuclear bomb testing. The release is a factor of 2.5 higher than the Chernobyl 133 Xe source term", although the "Xenon-133 [main noble gas] does not pose serious health risks ...
At 150 spots around the buildings the radiation was monitored. This map, the governmental data provided by SPEEDI (System for Prediction of Environmental Emergency Dose Information) and the data of the Japan Meteorological Agency's were shared – the same day – to the United States and other international institutes.
In April 2023, Japan's NRA announced a Comprehensive Radiation Monitoring Plan, in which the concentration of radionuclides in food (land and sea), soil, water, and air will be continually monitored across Japan. NRA also set up a system to monitor the radionuclide concentration in ALPS-processed water in order to verify TEPCO's readings.
Background radiation is a measure of the level of ionizing radiation present in ... Japan [4] Remark ... This global fallout has caused up to 2.4 million ...
