Radiological Survey of the Concentration Department in State Company of Phosphate. Frontiers in Environmental Microbiology. Vol. 6, No. 1, 2020, pp. 1-4. doi: 10.11648/j.fem.20200601.11 Received: December 31, 2019; Accepted: January 7, 2020; Published: January 17, 2020 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 .

Introduction Radioactivity and external exposure associated with gamma radiation depend primarily on the nature of the geological and geological characteristics that vary and vary from one region to another in the world [1, 2, 4]. Radioactivity is the emission of alpha (α) and beta (β) particles as well as gamma (γ) radiation from the unstable isotopes. Most minerals, that contain potassium, uranium and thorium, are radioactive [3, 5, 6]. Long-live radioactive elements such as uranium ( 238 U), thorium ( 232 Th) and potassium ( 40 K) and any of their decay products, such as radium and radon are examples of naturally occurring radioactive materials (NORM) [5-9]. Mining like many other industries can cause environmental impact [8-10]. However, for the NORM (Naturally Occurring Radioactive Material) industries, to the impact caused by conventional ways is added the radiological impact. Phosphates are used extensively, as a source of phosphorous for fertilizers and for manufacturing phosphoric acid and gypsum. Phosphate ores typically contain about 1500 Bq/kg of uranium and radium, although some phosphates contain up to 20,000 Bq/kg of U 3 O 8 [11]. Phosphate rocks with potassium ores and nitrogen compounds are among the main components used to produce fertilizers. Compounds are found to be important for plant growth. Phosphate rocks are used for the production of chemical fertilizers after phosphate extraction [4, 12]. The presence of radioactive isotopes of 238 U, 232 Thand 40 K In phosphates, the specific activity of radionuclides in phosphates is based on industrial output, which depends on their concentrations in the raw materials of phosphates (phosphate rock and phosphoric acid), as well as on the process of chemical separation during production processes Phosphate fertilizers [8, 11, 13]. The Iraqi State Company for Phosphate is located at Al- Qaim city with a coordinates (N 34.33465, E 41.18273). It is located at 150 km northeast of Akashat. The design capacity of the plant is one million tons of phosphate fertilizer annually. Phosphate rocks are transported from Akashat by the railway built for this purpose. Iraq have a huge amount of phosphate reserve more than 10000 MT which is located in the Western Desert of Iraq, Al-Anbar Governorate, Akashat site, 120 km southwest of the Euphrates river. These are among the largest phosphate reserve in the world. The amount of phosphogypsum waste produced by the phosphate industry is approximated to 20% of the ore
