Detecting of the Risk Indicator Parameters of Radioactive Nuclides Around the Stores of Fertilizer and Pesticides, Al Jazeera Agricultural Project Using the Germanium Detector

Abstract

This study shows the assessment of radiation hazard parameters due to terrestrial radionuclide's in soil around the residential areas near the stores of fertilizer and pesticides, Al Jazeera agricultural project Radiation hazard parameters were was computed. These include excess lifetime cancer risk, annual gonadal dose equivalent hazard index, radium equivalent activity and external hazard. Obtained result indicates that some of the radiation hazard parameters, the average value excess lifetime cancer risk (ELCR) 0.12 × 10 -3 µSv, were found to be lower than the UNSCEAR reported value of 0.29 × 10 −3 µSv (UNSCEAR 2000), and that of average annual gonadal dose equivalent hazard index 214.59 µSVyear -1 , the average value of AGDE in the region is the lower than worldwide average of 300 µSv/y (UNSCEAR 2000). the average radium equivalent Ra eq (Bqkg -1 ) 64.3 Bqkg -1 . The average external hazard index (H ex ) 0.18, the calculated H ex values for all the samples were found to be below unity, which does not cause harm to the populations of the investigated region. Radiation hazard parameters due to terrestrial radionuclide's in the soil samples were compared to the international values reported by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR, 2000) and previous studies on the region.
