Abstract
Uranium in ground and surface water may pose significant health hazards, if they are ingested via drinking pathway because of its radiological and chemical toxicities. Higher uranium concentration in drinking water can lead to serious diseases like leukemia, kidney cancer, stomach cancer and renal damages etc. In the present investigation, uranium concentration in groundwater samples of Mysuru district has been studied using an LED fluorimeter. About 350 water samples have been collected covering all the areas of Mysuru district and the uranium concentration varied from 0.34 to 242.93 µg l−1. The age depended dose due to uranium in drinking water has been estimated to evaluate the health hazards. The annual ingestion dose varied from 0.51 to 95.76 µSv y−1. The radiological and chemical toxicity risk to the population due to uranium in water was estimated. The Excess Cancer Risk varied from 1.22 × 10−6 to 102.63 × 10−6. The mean value of Hazard Quotient 0.07 indicates that the populations are less prone to adverse health effects of uranium contamination in water.
