قياس النشاط الإشعاعي الطبيعي في رواسب شواطئ الساحل الشمالي الشرقي لليبيا

In this study, we measured radiological hazards associated with beach sediments in the coastal area near the city of Al-Bayda, Libya. Radiation risk was assessed by estimating radium equivalent activity (Req), absorbed dose rate (DR), and annual effective dose rate (AEDR). As well as the external health risks(Hex) of the sediment samples collected. We Studies of naturally emitted gamma rays from the three radionuclides 226Ra, 232Th and 40 K. It was found that the average values of radioactivity were 8.26 Bq/Kg, 5.95 Bq/Kg and 66.1 Bq/Kg, respectively.
Gamma ray measurement was performed using the NaI (Tl) crystal detector technology. results indicates that the concentration of radioactivity corresponds to other countries of different regions the world. furthermore, radium equivalent activity (Req), absorbed dose rates (DR), and annual effective dose rate (AEDR), as well as external health risks (Hex) below average global values.
