Abstract

Background: Background radiation exists naturally in the environment and affects all living organisms. Assessment of these radiations is important because they cause somatic & genetic damages. This survey was carried out to determine the environmental gamma rate was measured in different seasons in Kermanshah towns, and the effective dose for the residents of these regions was calculated.

Methods: gamma dose rate was determined by Geiger Muller detector (RADOS CO, RDS-120).To this end, six and seven stations were selected in outdoor and indoor areas, respectively. In other towns‚ however, the measurements were performed at one station in outdoor center of each town.

Results: The mean values of indoor and outdoor gamma dose rates in Kermanshah were 99.96 and 118.6 nSv/h, respectively and the mean values of environmental gamma in outdoor areas of Islamabad-e-Gharb‚ Songhor‚ Sahneh‚ Gilan-e-Gharb, Sarpol-e-Zahab‚ Ghasr-e-Shirin‚ Harsin‚ Paveh‚ Ravansar and Javanrood towns were 99.96 ‚ 120.5 ‚ 143 ‚ 115.7 ‚ 71.7 ‚ 76.2 ‚ 82 ‚ 108.5 ‚ 95.7‚ 95.7 and 106 nSv/h, respectively. Also, the highest and the lowest annual effective dose were reported for Songhor (0.88 mSv/y) and Gilan-e-Gharb (0.44mSv/y), respectively.

Conclusion: The outdoor annual effective doses for the residents of Kermanshah‚ Islamabad-e-Gharb‚ Sahneh‚ Gilan-e-Gharb‚ Sarpol-e-Zahab‚ Ghasr-e-Shirin‚ Harsin‚ Paveh‚ Ravansar and Javanrood were lower than the global value (0.76 mSv/y) except for Songhor with 16% higher dose.
