An Evaluation of Radon Concentrations in Arin Lake, Bitlis

Abstract Arin Lake, situated in the Bitlis province, is a soda lake that holds significant ecological importance as a habitat for migratory bird species such as flamingos and white-headed ducks. In order to investigate the potential radiation exposure to the environment and living organisms in the area, radon concentration levels and dose calculations were determined for water samples collected from 27 different points in Arin Lake. The radon levels were determined using the AlphaGUARD PQ2000 PRO radon monitoring system, which has the range of 2–2.10 6 Bqm −3 . The results of the radon concentration measurements are between 0.06 and 0.39 Bq/L, with a mean of value of 0.17 Bq/L. The annual effective doses for ingestion ( D eff-ing ) and inhalation ( D eff-inh ) were calculated at values ranging from 0.14 to 0.99 µSv/year. The radon levels were found to be lower than international standard values. Furthermore, the outcomes of this research were subjected to comparison with other studies in the literature.
