Estimation and Comparison of Inhalation Doses at Fukushima and Thailand in Its Students’ Rooms

Abstract

Estimation of internal radiation doses due to radon/thoron inhalation was carried out in Fukushima-Japan, and Thailand. A passive monitor (RADUET) developed by Tokonami et al.¹⁾ was used to measure radon and thoron. The RADUET was settled in the rooms of high school students and an university student for four months. The estimated radiation doses from RADUET system were 0.53±0.08 mSv/year in the rooms of Thai students (n=3) and 0.25 mSv/year in the room of university student in Fukushima. The results showed that the radon/thoron internal radiation doses in Fukushima and Thailand were not significantly different.
