Outline of Final Research Achievements

The purpose of this research is a beta-ray dose estimation due to radioactivities from Fkushima accident. Beta dose in air and skin dose were estimated using Monte Carlo calculation. The results were published as 2 papers in Journal of Radiation Research (1. beta dose rate in air near ground surface at the condition of 1000 kBw/m2 deposition and 2. cumulative dose map combined with 2km mesh investigation by MEXT). And then, related 8 publicaitions are made.
