    238u and Total Radioactivity in Drinking Waters in Van Province, Turkey
    (Taylor and Francis Ltd., 2014) Selçuk Zorer, Ö.; Daǧ, B.
    As part of the national survey to evaluate natural radioactivity in the environment, concentration levels of total radioactivity and natural uranium have been analysed in drinking water samples. A survey to study natural radioactivity in drinking waters was carried out in the Van province, East Turkey. Twenty-three samples of drinking water were collected in the Van province and analysed for total α, total β and 238U activity. The total α and total β activities were counted by using the α/β counter of the multi-detector low background system (PIC MPC-9604), and the 238U concentrations were determined by inductively coupled plasma-mass spectrometry (Thermo Scientific Element 2). The samples were categorised according to origin: tap, spring or mineral supply. The activity concentrations for total α were found to range from 0.002 to 0.030 Bq L-1 and for total β from 0.023 to 1.351 Bq L-1. Uranium concentrations ranging from 0.562 to 14.710 μg L-1 were observed in drinking waters. Following the World Health Organisation rules, all investigated waters can be used as drinking water. © 2013 © 2013 Taylor & Francis.
