Abstract:
The research work involved the ingestion and inhalation doses due to the intake of radon and uranium through water samples used by the inhabitants, measured in the villages of the Shiwalik Himalayas of Jammu and Kashmir, India. The uranium concentration in collected water samples was assessed by LED fluorimetric technique. All values of doses were found to be below the proposed limit of 100 μSv year⁻¹ for all age categories except for infants due to the high-dose conversion factor. The annual effective doses for the various body organs due to the intake of radon was also calculated and found the maximum dose for lungs than other organs. The concentration of radon in water samples was assessed by Smart Rn Duo portable monitor and compared with RAD7. Statistical analysis was carried out and the Shapiro and Wilk (Biometrika, 52(3/4), 591–611, 1965) test has been also used for the distribution of the data. The physicochemical parameters were also measured in the collected water samples.
