چکیده
|
A large amount of the fission products released by the fukushima daiichi nuclear power plant (fdnpp) accident on 11 march 2011 was deposited in a wide area from tohoku to northern kanto. a map of the estimated cumulative β-ray dose (70 μm dose equivalent) on the soil surface for one year after the fdnpp accident has been prepared using previously reported calculation methods and the 2-km mesh survey data by mext. from this map of estimated dose,areas with a high cumulative β-ray dose on the soil surface for one year after the fdnpp accident were found to be located in the akogi-teshichiro to akogi-kunugidaira region in namie town,and in the southern futaba town to the northern tomioka town region. the highest estimated cumulative β-ray dose was 710 msv for one year at akogi-teshichiro,namie town. © 2015 the author.
