摘要

A convenient radon detecting device for the purpose of estimating natural radiation exposure is described. The a radioactivity of radon gas adsorbed in fine active carbon particles exposed to air is measured with a liquid scintillation spectrometer (Packard-PICO-RAD system). Its detection limits are 2 mBq/ E in air and 0.5 Bq/ E in water with an accuracy of about 10%. Radon concentrations at Misasa hot springs in Tottori prefecture were measured using this method. They were 0.16--7.7 Bq/£ in a bath room and 0.057--0.36 Bq/£ outdoors. Radon concentrations of the hot springs were 82--1, 700 BqjE.
