Abstract
Radon, a radioactive gas that emanates naturally from the earth crust is accountable for about 50% of the effective dose of ionizing radiation received by humans. Most radon susceptiveness occurs in homes and work places, it comes from the natural disintegration of uranium in soil, rock and water and escalate to the air that we breath, hence it is important to monitor the actual level of exposure in most buildings. This work analysed the indoor radon concentration in air at twenty different offices of different building at Bells University of Technology using Rad7 detector. The mean measured radon concentration ranges from 0-56.7 Bq/m3 for all the study locations. The mean absorbed dose, equivalent dose and effective dose were calculated with the radon concentration which are 0.152 mGy/y, 3.045 mSv/y and 0.365 mSv/y respectively. The results obtained are below the world set limit as recommended by International Commission on radiological protection, except for office 7 which slightly exceed the recommended limit. Thus, the study concluded that good ventilation is very important in the reduction of radon concentration level in our work places.
