| dc.description.abstract | In this study, the assessement of the outdoor background radiation levels in Abzat quarrying sites in Keffi, Nasarawa State has been studied. The outdoor in-situ background exposure rate level for thirty (30) quarryng spots were done using a well calibrated portable halogen-quenched Geiger Muller (GM) detector (Inspector alert nuclear radiation monitor SN: 3544) at 1 m hieght above above ground level. The spots where the measurement were taken, a Global Positioning System (GPS) was used to record the geopoints. Radiological health hazards parameters and radiation effective doses to different body organs were evaluated using the measured exposure rates values. The values of radiological hazard paramaters obtained were compared with recommended permissible limits set by International Commission on Radiological Protection (ICRP) and United Nations Scientific Committee on the effect of Atomic Radiation (UNSCEAR) for hazard evaluation.. The mean values of the outdoor background exposure levels (0.0945 mRh'1), absorbed dose rates (822.44 nGylr1) and excess lifetime cancer risk (3.53.x 10**;) arc higher than the recommended safe limits of 0.013 mRh'1, 84.0 nGyh'1, 0.29xl0'3 respectively .as recommended by UNSCEAR and ICRP. The mean annual effective dose equivalent (1.00 mSvy'1) is within the recommended pennissible limits of 1.00 mSvy*1 for general public exposure and the effective doses to different body organs are all below the recommended limits of 1.0 mSvy'1. The background exposure level in Abzat quaring site is relatively safe with a potential of posing health risk on residence of the area in years to come due to doses accumulated. | en_US |
