قياس تراكيز النظائر المشعة الطبيعية 232Th,U238, 40K و تقدير المخاطر الخارجية و الداخلية الناتجة عنها باستخدام منظومة (GR-460)‎ في مركز محافظة النجف الاشرف

Abstract EN

This study included the measurement of concentrations of radioactive isotopes (238U,232Th, 40K) and doses of radiation caused by them .The isotopes generated by the Uranium , Thorium and actinium series .The equivalent concentrations of Radium, assess external and internal risks arising from the three isotopes at the center of the province of Najaf were calculated and compared the results with limits internationally Qays Abdul Ameer Dawood and Muayd Abdul- Hussein Abase1, Sahib Neamah Abdulwahid Alkulaibi2 Iraqi Radioactive Sources Authority Regulatory (IRSRA), kufa university/college of education for women/physics department permitted values was conducted research during the mobile radiation detection system (GR-460), alternative method for the traditional way of snapped models of soil and a measurement process models ,from the radiation detection system (GR-460), obtained the equivalent of radium concentration of radium 226Raeq rate, the rate of external risks (Hex) and internal risks (Hin) .The annual rate of potions influential (AEDEoo) and internal (AEDEio) were respectively (108.48 Bq / kg), (0.292), (0.441), (0.046) and (0.186 mSv/y).All the above values are considered to be within allowable limits globally.
