An important route of human intake of uranium and other radionuclides, especially when the general population is considered is by ingestion through drinking water. The present study conducted around Chickmagalure, Karnataka, India. The concentration of uranium in natural waters is generally found to be very low, often being of the order of few parts per billion (ppb). Laser Flourimetry has been used to estimate the uranium concentration in drinking water. Uranium concentrations are found to vary from 0.2 to 27.9 ppb (g.l^-1) with a geometric mean of 3.7 ppb. The daily intake of uranium by the local population of the study region varies from about 0.8 to 111.6 g.d^-1.
