| Abstract: | This study is part of an effort to assess the level of background radiation for Erzincan Province of eastern Turkey. Radionuclide
activity concentrations in soil samples were measured through gamma-ray spectrometry and the average activities were determined
as 8.93, 11.39, 281.94, and 9.52 Bq/kg for the radionuclides 238U, 232Th, 40K, and 137Cs, respectively. The average annual effective dose from these natural radioactivity sources (238U series, 232Th series and 40K,) was calculated to be 27.9 μSv. Radioactivity levels in drinking and potable water samples were studied using a multi-channel
low level proportional counter. The average gross alpha activity concentration was found to be 0.0477 Bq/L (min. 0.007 Bq/L;
max. 0.421 Bq/L) and the average gross beta activity was measured as 0.104 Bq/L (min. 0.008 Bq/L; max. 1.806 Bq/L). These
values lead to an average annual effective dose of 9.75 μSv from the alpha emitters and 56.34 μSv from the beta emitting radionuclides
in water. The radioactivity levels in the water samples investigated were found to comply with the reference levels recommended
by WHO and the regulations set forth by the Turkish Health Ministry. |
