Investigation of Radioactivity Levels for (137)Cs and Evaluation of Absorbed Dose Rate and Annual Effective Dose in Soil Samples Collected from different locations inside the city of Agdabya, Liby

الملخص

This is the first time that radiological assessment achieved in these locations inside the city of Agdabya, Libya. Twelve sites were sampled from upper 5 cm of the surface soil to be analyzed for the radioactivity of artificial radionuclide, Cesium-137( (_ ^137)Cs ),the absorbed dose rate and annual effective dose rate using gamma spectroscopy based on Hyper Pure Germanium detector (HPGe). Samples were measured at Radiological measurements and training center, Tripoli. The results showed that the radioactivity of Cesium-137( (_ ^137)Cs) , absorbed dose rate and annual effective dose rate have average values of 0.418Bq.〖Kg〗^(-1) , 0.013nGy.h^(-1)and 0.015μSv.y^(-1) respectively. These values were found to be less than the world average values recommended by ICRP. [1]
