Mining and processing of uranium ore leaves behind large quantity of waste called tailings. The waste is neutralized and separated into coarse and fines prior to their confinement into safe depository. Such confined waste has got the potential to modify the natural radiological environment around the industry. Since operations at UClL has completed four decades at Jaduguda and more sites is being proposed in the Singhbhum region a comparative study is required to evaluate the changes incurred during the operations at Jaduguda. The results of the study reveal that so far the variation in radionuclide level in ground water and soil is natural and effect of UClL operations is insignificant. The treatment of tailings effluent is effective enough to reduce the level of U(nat) and ²²⁶Ra much below the DWC of 60 mg.m^-3 and 300 Bq.m^-3. Elevated levels of these radionuclides have been found in soil samples around the opencast deposit at Banduhurang. Near Banduhurang the level of U(nat) varied from 5.4 to 28.8 rng.kg^-1 and that of ²²⁶Ra varied from 18.5 to 211 Bq.kg^-1. Elevated levels of ²²⁶Ra have been found in artesian wells around Jaduguda with maximum concentration of 706 Bq.m^-3 in water and 3809 Bq.kg^-1 in soil around this.
