Geographical distribution of environmental radiation

Creators

  • 1. National Inst. of Radiological Sciences, Chiba (Japan)

Description

The dose rate of environmental radiation is higher in the western part of Japan as compared with the eastern part. The relation between the nature of the soil and the natural radiation was studied. For example, in Shikoku, the natural radiation dose is higher in the northern strata than in the other parts. Dose values were classified according to rocks, and granite showed high value while valcanic ash showed relatively low value. (Yamamoto, Y.)
