Abstract
The purpose of this research is to conduct a radiological survey of the crushing, milling, screening and conveyor unit of raw materials in the al-Qa'im fertilizer plant/General Phosphate Company, in order to calculate the absorbed doses of the workers in these places as well as the work hazards. As the raw materials in the phosphate fertilizer industry are extracted from the ground, Certainly contains radioisotopes such as the series of decay of uranium, thorium and potassium, which is the main cause of radiation activity in raw materials and the results of the dose absorbed to the workers in the unit of grinding, cracking and screening, And the conveyor belt for raw materials is (0.34, 0.38) mSv/y respectively, which is less than the internationally allowed limits (1msv/y) and the risk of working on working persons (1.7×10-5, 1.9×10-5) For crushing and crushing unit and belt conveyor unit, respectively, within the limits of internationally licensed 10-5.
