Title: Simultaneous measurement of Rn and its progeny in cave air by liquid scintillation techniques and. cap alpha. -ray spectrometry

Abstract

To estimate the internal dose from Rn and its progeny, the working level month which is defined as exposure at one working level concentration for 170 h has been used traditionally. But concerning dose calculated for the inhalation of Rn and its progeny to the public, dose factors from individual nuclides were recommended. The approach using individual dose factors requires determination of the concentration of these individual nuclides. Thus a simultaneous measurement of Rn and its progeny was made in an enclosed cave, which is used for seismological observation, since the problem is most acute in an enclosed environment and the situation is not so complicated under such circumstances. Radon sampling by adsorption in organic solvent and in-situ ..cap alpha..-ray spectrometry of Rn progeny have been carried out in this cave. The internal dose by inhalation is estimated for the workers in this cave.
