Abstract

The main objective of this research is measurement and assessment of the Radon-222 and Radium-226 radioactive levels in mineral water and drinking water in the Sareyn city. The guidelines used for Radon-222 and Radium-226 radiation sampling and analysis were ASTM D: 5072-09 and ISO 13165-1: 2013, respectively. The concentration of Radon-222 and radium-226 in mineral water and drinking water samples was measured by Liquid Scintillation Counter (LSC). The results of the measurements show that the Radon-222 radionuclide concentration in mineral water samples is 1.14-6.71 Bq/L and 4.25-9.72 Bq/L for drinking water samples. Furthermore, Radium-226 was determined in mineral water samples in the range of 0.048-0.248 Bq/L and in drinking water samples in the range of 0.044-0.078 Bq/L. Consequently, Radon-222 and Radium-226 radioactivity concentration in all samples of drinking water are below the permissible limit. However, Radon-222 radioactivity concentration is higher than the standard level in a number of springs that few people use as a source of drinking water. Nevertheless, in order to ensure more than the non-contamination of drinking water sources in Sareyn, radionuclides of Radon-222 and Radium-226 can be systematically evaluated and considered by the proposed method.
