ABSTRACT
The field of this research was the radiation in the buildings of the Department of Physics, Faculty of Science, University of Kufa using a portable radiation dosimeter. The values of the inner room absorbed dose rate varied from 0.053±0.004 to 0.143±0.008 µSv/h-1 with an average 0.097±0.004 Sv/h-1, while the outer room absorbed dose rate varied from 0.053±0.005 to 0.110±0.007 µSv/h-1 with an average 0.088±0.008 µSv/h-1. The average annual effective doses inside and outside rooms were 0.090±0.004 and 0.081±0.008 µSv/h-1, respectively, while the cancer risks inside and outside rooms were (0.17±0.008) × 10-3 and (0.16±0.001)× 10-3, respectively. All results of the dose rate, annual effective dose and excess lifetime cancer risk in all locations under study were within the allowed limits of 0.274 µSv/h-1, 0.48 µSv/h-1, and 0.29 × 10-3, so the physics department was safe to work in and did not constitute a danger or hazard to the students, staff and teachers.
