Measurement the natural radioactivity of soil samples from selected regions in Wassit Governorate

Abstract EN

-In this paper, the measurement of natural radioactivity in soil samples from different regions of Wassit governorate by using (HPGe) detector, The results of measurements have shown that the average specific activity concentrations for U-238, Th-232 and K-40 were (22.220±4.3 Bq/kg, 25.305 ±3.7 Bq/kg, 181.446±40.4 Bq/kg) respectively, which was less than the worldwide average given by (UNSCEAR , 2000).

While the average values of [Hex, Hin, Iɣ , (AED) out , (AED) in, DƔ, Raeq], for each sample were found to be (72.377±7.3 Bq/kg, 33.116±3.4 nGy/h, 0.162 ±0.017mSv/y, 0.041 ±0.004 mSv/y, 0.522 ±0.05, 0.256 ±0.03, 0.195 ±0.02), respectively, all of these values were lower than the permissibility limit value given by (UNSCEAR , 2000).
