Mapping of gamma emitters for soil samples in Kerbala University, Kerbala governorate.

In present study Sixty soil samples were collected from different locations of Karbala University in (Fariha site), The specific activity of 238U, 232Th, and 40K for samples were measured using gamma ray spectroscopy system with NaI(Tl) "3×3" detector. The results showed that, the specific activity of 238U, 232Th and 40K were ranged from (35.3±1.7 to 3±0.35) Bq/kg, (2.8±0.21 to 8.22±2.9) Bq/kg, (447.4±6.2 to109.2±2.3) Bq/kg respectively, while the results of average value for radiological hazard index were (51.96±1.38) Bq/kg in radium equivalent activity (Raeq), (0.14±0.004) and (0.186±0.007) in external (Hex) as well as internal hazard (Hin) index respectively, and ,(25.38±0.883) nGy/h of absorbed dose rate (Dr). When looking at comparing the results of the current work with the global average, we found that the values were within recommended values provided by (UNSCEAR, 1994 and UNSCEAR, 2008). In other words, soil samples of Kerbala University were Safe for dose and did not pose a danger or hazard to the citizens, to the residents. [ABSTRACT FROM AUTHOR]
