Measurements of radon concentrations in spa waters in Amasya, Turkey.

Radon concentration measurements were performed in four spas used for therapy, drinking and irrigation purposes in the Amasya basin in Turkey, during a period of time between January 2009 and May 2010. The measurements were done using commercially available WG-1001 Vacuum Water Degassing System and the AB-5R Radiation Monitor manufactured by Pylon Electronics. The observed radon concentration values ranged from 0.11 to 0.71 Bq L⁻¹. Effective doses from inhalation of radon released from spa waters have been estimated between 0.28 and 1.78 µSv y⁻¹ .

Radon concentrations in water in the region of Tokat city in Turkey.

The aim of this study is to measure the radon ((222)Rn) concentrations in drinking water and river water in the region of Tokat city in Turkey. The measurements were performed by analysing the water samples collected from tap water, spring water and Yesilirmak river water flowing through the centre of the city of Tokat. The obtained radon concentrations ranged from 0.48 ± 0.22 to 1.30 ± 0.27 Bq l(-1) in tap water, from 0.13 ± 0.17 to 1.20 ± 0.29 Bq l(-1) in spring water and from 0.09 ± 0.12 to 0.83 ± 0.17 Bq l(-1) in the Yesilirmak river water. The results are presented and compared with other studies. From these data, the average effective dose equivalent from radon in tap water and in spring water has been estimated as 5.0 and 3.0 µSv y(-1), respectively.

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

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 microSv y(-1).
