抄録
Since 2008, we have measured 137Cs and 239,240Pu isotopes in about 60 soil samples from the under-floor of 20 houses built within 1-3 years after 1945, in order to evaluate the close-in fallout deposition due to the "Black rain" at the time of Hiroshima atomic explosion. 239,240Pu was used as indicator to evaluate the contamination from global fallout 137Cs other than Hiroshima A-bomb derived 137Cs.

As a result, it seems likely that 137Cs deposition at that time due to the Hiroshima A-bomb is 50-100 Bq/m2.
