Abstract
This study aims to evaluate the effect of various ventilation parameters on radon concentration and inhalation exposure of miners in underground uranium mines. The study carried out at Jaduguda mine revealed that the airflow rate plays a significant role in controlling the radon and its daughter concentrations in the mine. The equilibrium equivalent radon concentration in the mine stopes varied from 180 to 402 Bq m−3. Under existing ventilation condition of the mine, the average inhalation exposure of miners was estimated to be 0.42 WLM year−1, which is about 10 % of the current threshold limit of 4 WLM year−1.
