Description

The purpose of this research was to measure indoor radon concentration in the area of Ban Pang Faen, Pa-Miang subdistrict, Doi-Saket district, Chiang Mai Province. Radon measurements were performed in 59 sites from February 27 to June 24, 2017 for 115 days by using plastic alpha track detectors or CR-39. The results of indoor radon gas concentrations in bedroom and living room were 28±14 to 143±47 Bq/m$^{3}$ and 26±19 to 322±109 Bq/m$^{3}$, respectively. Radon levels in 4 sites were higher than 148 Bq/m$^{3}$ which is taken as the action level by the United States Environmental Protection Agency (U.S.EPA). Then, the average annual effective dose of residents were calculated from radon concentration, using equation, which is introduced by UNCLEAR and were found to between 0.21 to 1.71 mSv/year. The average annual effective dose of 31 residents are above the dose limit of 1 mSv/year recommended by the International Commission on Radiological Protection (ICRP).
