The measurements of radon concentrations in drinking water and the Yesilirmak River water in the area of Amasya in Turkey

Abstract

This paper presents the results of radon ((222)Rn) concentrations in drinking water and river water. In this respect, water samples were collected in the city of Amasya, inner parts of the Median Black sea region in Turkey and the Yesilirmak River flowing through Amasya city centre. It was found that the concentrations in tap water, spring water and the Yesilirmak River water in Amasya ranged from 0.42 +/- 0.14 to 2.4 +/- 0.32 Bq l(-1), 0.39 +/- 0.19 to 1.17 +/- 0.21 Bq l(-1) and 0.28 +/- 0.04 to 1.08 +/- 0.30 Bq l(-1), respectively. From these data, the average effective dose equivalent from radon in tap water has been estimated as 5.87 mu Sv y(-1).
