  • * Total radiation doses were generated 104 times for each study area from three exposure distributions. Only physical decay of radiocesium was considered to project the dose rates in 2022 and 2062. Variation in time of cesium in soil, food, and aerosols other than physical decay was not considered.

  • Eight sets of outlying data of the personal external dose rate in the village of Kawauchi were included and fitted to a log-normal distribution.
