Description

The purpose of this study was to determine the radon concentration in water for consumption from Ban Pongkum region, Doi Saket district, Chiang Mai Province. All samples were collected from 9 sites including 7 well water samples, 1 tap water and 1 hot spring (spa pool). Radon concentration was measured with using RAD7 H2O. The results showed that the average of radon concentrations were 57.54±25.23 Bq/l, 60.90±14.17 Bq/l and 13.17±4.15 Bq/l in well, tap water and Doi-saket hot spring water (spa pool), respectively. Radon concentration in all samples were below the United States Environmental Protection Agency maximum contaminant level (U.S.EPA MCL) of 150 Bq/l. Annual effective dose resulting from radon in all samples ranged from 0.004 to 0.033 mSv/y which lower than ICRP recommended limit for members of the public of 1 mSv/y.
