Estimation the radiological hazard effects for soil samples of Ajmail city, Libya

الملخص EN

The specific activities of twenty-five soil samples have been measured with gamma ray spectrometry system using a High Purity Germanium (HPGe) detector in order to evaluate the radiological hazard effects of the natural radioactivity, the activity utilization index(AUI), Gamma Index (I_γ), alpha index (I_α) and the radiation exposure rate (I), The annual effective dose indoor AEDE(Sv y-1)indoor , and outdoor AEDE(Sv y-1)outdoor have been calculated.

The activity utilization index values ranged from 0.06 to 0.34 with an average 0.15, and Gamma Index (I_γ) values ranged from 0.142 to 0.372 with an average of 0.2028, while the alpha index values ranged from 0.025 to 0.117 with an average 0.049, and the values of radiation exposure rate (I) ranged from 39.02 µR/h to 102.66 µR/h with an average value of 56.34 µR/h.
