Abstract
More than 50% of the radiation dose received by underground mine workers is mainly due to the inhalation of radon (222Rn) gas and its decay products in an underground mine working space. Monitoring and controlling of 222Rn exhalation in the underground mine working plays a vital role in minimizing the radiation risk hazards to the mine-workers. This study discusses the contribution of mine water and uranium ore to 222Rn activity concentration in mine air and its health risk assessment. The annual effective radiation dose (ERn) due to inhalation of 222Rn for mine workers is estimated 0.10 mSv/y. Furthermore, the estimated Excess lifetime cancer risk (ELCR) and radoninduced lung cancer per million per person (RnLCC) is found to be 0.3 x 10-3 and 0.002 x 10-6. The estimated results of ERn and RnLCC due to the inhalation of 222Rn are well within the prescribed limits of the International regulatory agencies.
