Detection of Activity Concentration, Dose Rate, Absorbed Dose and Effective Annual Dose of Radionuclide's Around Fertilizer and Pesticide Stores, Al-Jazeera Project in Sudan

摘要

This paper demonstrates the evaluation of radiological risk factors due to terrestrial radionuclides in soil, about the stores of pesticides and fertilizers for Al-Jazeera agricultural project in Al-Hasahisa, Sudan, to address the issue of the natural radioactivity of this area. Hence, levels of ~(226)Ra, ~(232)Th, ~(228)Ra, ~(40)K and ~(137)Ci in the soil were calculated (by using germanium detector), and then the radiation risk parameters were calculated. its including radioactivity concentration Bq/kg, absorbed dose D, and effective annual dose E, its due to inhalation of radon (222Rn) and consumption of potassium (~(40)K), radium (~(226)Ra), radium (~(228)Ra), thorium (~(232)Th) and mean activity concentrationsdeviation The norms for the five primitive radionuclides were, respectively, 268.985.22, 14.540.2, 15.311.54, 20.450.96, and 0.340.19 Bq kg~(-1). This results somewhat normal distribution of the United Nations Scientific Committee on the Effects of Atomic Radiation. The results obtained indicate that some radiation risk factors appear to be unfavorable. The mean average absorbed dosestandard deviation (30.542.71) nGyh~(-1) was a slightly normal distribution of the average value of 30.54 nGy/ h, and the Average annual effective dose E (SVyear~(-1))standard deviation (37.483.32).) SVyear~(-1) was a slightly normalized distribution of the value of SVyear~(-1) its compared with the data of the United Nations Scientific Committee on the Effects of Atomic Radiation. The study focuses light on the demand to develop a comprehensive program for radiation protection in Sudan and in agricultural projects that constantly use pesticides and fertilizers for regulatory oversight.
