Measurement of annual effective dose of radon gas in glass and plastic greenhouses in Mosul city

Abstract

The present study measures the radon concentration and the annual effective dose in greenhouses in Mosul city during winter season (2012) . Long term measurements of radon concentration have been taken , using previously calibrated passive diffusion dosimeters containing CR-39 solid state nuclear track detectors which are very sensitive to alpha particles . The measurements of radon concentration obtained at winter season in greenhouses ranged between 85.8 Bq.m-3 in glass greenhouse in Mosul technical institute and 101.8 Bq.m-3 in plasic greenhouse in Al- khadhraa nursery. Also the annual effective dos ranged between 2.16 mSvy-1 in class greenhouse in Mosul technical institute and 2.56 mSvy-1 in plasic greenhouse in Al- khadhraa nursery .
