[MAG33-03] Analysis of charcoal fragments in soils from Black Rain areas (Preliminary)

*Jun Inoue¹, Yuya Ihara¹, Meteorological and Soil Working Group "Black Rain" (1.Osaka Metropolitan University)

It has been suggested that the black rain following the atomic bombings may have contained charcoal particles. This implies that analyzing charcoal particles in soils collected from areas potentially affected by the black rain could help determine the extent of the rainfall. Therefore, we quantified the charcoal content in soil samples from these areas to assess the effectiveness of charcoal analysis in delineating the rainfall boundaries.
