A preliminary study on soil-gas radon geochemistry according to different bedrock geology in korea

摘要

Three study areas of Kwanak campus (Seoul national Univerisyt), Boeun (Choong-buk) and Gapyung (Kyonggi) were selected and classified according to their bedrock types in order to investigate soil-gas radon concentrations. The mean values of radon concentrations decreased in the order of Gapyung (40 BqL~-1)＞Kwanalk campus (30BqL~-1)＞Boeun(22BqL~-1), and decreased in the order of granite gneiss＞banded gneiss＞granite＞black slate-shale＞mica schist＞shale- limestone＞phyllite schist according to bed rock types.
