The fission track technique has been used to estimate the U concentrations in water samples collected from the Hamirpur, Una, Bilaspur and Kangra districts of Himachal Pradesh, India.
The sources comprise wells, springs, a municipal supply (tap water) and drains.
The smallest U concentration of 0.06 ± 0.01 ppb has been found in the spring water of Palampur city and the highest concentration 20.94 ± 0.14 ppb was in the drain water of Samurkalan village.
A comparison of the U concentrations in nearby sources, and the time variation in a particular source, have been assessed.
The dissolved Rn-222 content in some of these sources has also been estimated in situ by radon emanometery.
The risk of health hazard due to ingestion of the dissolved radon has been assessed.
