222Rn decay products are known to be deposited on the Japan Sea side of the sea in winter. However, there are only a few measurement points, so it is difficult to evaluate the distribution of deposition.Therefore, we will elucidate the relationship between air dose rate increases measured at monitoring posts that are spatially densely located to estimate the deposition distribution.
