Survey of Absorbed Dose Rates in air of Buildings Agriculture and Sciences in University of Kufa at Al-Najaf Governorate, Iraq

Abstract

Indoor and Outdoor absorbed dose rates were measured in select region of AL-Qizweenia Najaf in Iraq. Measurements were perform using a Portable dosimeter Survey (Inspector Alert Model RAP RS1,S.E.international,Inc, USA). The results show that the values of absorbed dose indoor and outdoor were ranged from 696 to 1592.1 nGy/hr and from 565.5 to 1070.1 nGy/hr respectively. The average absorbed dose indoor and outdoor rates were 950.91 nGy/hr and 810.84 nGy/hr of every buildings and laboratories. According to occupancy factor of 0.8 and 0.2, the corresponding average annual effective dose indoor and outdoor rates were calculated to be, 4.66 mSv/yr and 0.99 mSv/yr, successively. The mean annual effective dose outdoor rate is found to be higher than 1mSv/yr which is the recommended dose limit for the public.
