Abstract To strengthen the radiation protection infrastructure in Bathinda, the uranium concentration indaily diet of the residents has been measured and its associated radiation risks were estimated for the adultpopulation. Food samples were collected from major cancer prone areas of the district, from which daily dietswere prepared. These diet samples were analyzed using fission track technique. The measured values of theuranium content were found to vary from 0.38 mBq/g in mustard seeds to 4.60 mBq/g in wheat. In case of milkthe uranium content is found to vary from 28.57–213.36 mBq/ with mean concentration of 61.35 mBq/ . Thisleads to a daily dietary intake of 0.90 Bq/day. The measured value of 0.90 Bq d–1, contributes to 1.12 mSv to thecumulative effective dose to the population. This dose is much large than the International Commission forRadiological Protection (ICRP) annual effective dose limit of 1 mSv for the general public [1]. Therefore, it wouldpose significant health hazard.
