Radionuclides find their way into the water resources at sites in the vicinity of nuclearfacilities involved in mining, milling, ore separation, purification, etc. The presentedstudy delineates the distribution of radionuclides {Ra and U(nat)} in groundwatersexisting in the vicinity of two proposed uranium mine sites and evaluates their ingestiondose through the intake of drinking water. The study reveals that the U(nat) concentrationin groundwater varied from <0.5 to 11.2μg.l-1 in the Bagjata mining area and from<0.5 to 27.5 μg.l-1 in theBanduhurang mining area, while 226Ra was found in the range of <3.5 to 206 mBq.l-1 and<3.5 to 82 mBq.l-1, respectively, for both areas.Seasonal variation and distribution of radionuclides in the study area did not show anydefinite pattern. A strong positive correlation of U(nat) in groundwater with pH andnegative correlation of 226Ra with pH is shown in the study. The ingestion doseto the public through intake of drinking water is estimated as 9.43μSv.y-1 for Bagjata and 6.28μSv.y-1 for Banduhurang, which is much lower than thereference limit (100 μSv.y-1) given by the WHO.
