Abstract

 Background: Background: Natural background radiation is the main source of human exposure to radioactive material.Soils naturally have radioactive mineral contents. The aim of this study is to determine natural (238U, 232TH, 40K) and artificial (137Cs) radioactivity levels in wheat and corn fields of Eilam province.Methods: HPGE DETECTOR was used to measure the concentration activity of 238U and 232TH series, 40K and 137CS in wheat and corn samples taken from different regions of Eilam province, in Iran.Results: In wheat and corn samples, the average activity concentrations of 226RA, 232TH, 40K and 137CS were found to be 1, 67, 0.5, 91.73, 0.01 and 0.81, 0.85, 101.52, 0.07Bq/kg (dry weight), respectively. Hex and Hin in the present work are lower than 1. The average value of Hex was found to be 0.02 and 0.025 and average value of Hin to be found 0.025 and 0.027 in wheat fields samples and corn samples in Eilam provinces, respectively. The obtained values of AGDE are 30.49 mSv/yr for wheat filed samples and 37.89 mSv/yr for corn samples; the AEDE rate values are 5.28 mSv/yr in wheat filed samples and this average value was found to be 6.13 mSv/yr in corn samplesin Eilam. Transfer factors (TFs) of long lived radionuclide such as 137CS, 226RA, 232TH and 40K from soils to corn and wheat plants have been studied by radiotracer experiments.Conclusion: The natural radioactivity levels in Eilam province are not at the range of high risk of morbidity and are under international standards.
