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 play 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 at 0.10 mSv/y. Furthermore, the estimated excess lifetime cancer risk (ELCR) and radon-induced 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.
