Abstract

The activity concentration of natural radio nuclides such as 226Ra, 238U, 228Th and 40K were determined in river sediment samples collected from Kanyakumari district. The measurements were carried out using a 3” × 3” NaI Gamma spectrometry. The mean radionuclide activity concentrations obtained for each of the radio nuclides expressed in Bq/Kg are18.85, 8.71, 18.75 and 148.10 for 228Ra, 238U, 228Th and 40K respectively. The mean absorbed dose rate is 21.77 nGy/h-1. The activity concentration was found to be less than the recommended level of international guide lines and would not pose any significant radiological impact on the environment.
