Abstract
Fifteen samples of soil were chosen to achieve this work, the samples were obtained from– Al jabel Algharbi - Awiniya region, Libya. Distributions of natural radionuclides of 238 U, 232Th and 40K in these samples were determined using a high-purity germanium detector (HPGe) with a specially designed shield. The content of uranium, thorium and potassium is lower than permissible levels in all soil samples. To evaluate the radiological hazard from soil in this area the radium equivalent activity (Raeq), absorbed gamma dose rate (D), annual effective dose equivalent (AEDE), external hazard index (Hex) and excess lifetime cancer risk (ELCR) were calculated in this work. The levels of natural radioactivity and radiation hazard parameters were compared with the international recommended values. All obtained results were found to be below the international recommended limit.
