title: Study of radionuclide distribution around Kudankulam nuclear power plant site (Agastheeswaram taluk of Kanyakumari district, India).
abstract: The activity concentration of primordial radionuclides 238U, 232Th and 40K have been measured in the sand samples of Agastheeswaram taluk of Kanyakumari district using gamma-ray spectrometer. The average activity of 232Th, 238U and 40K are found to be 5787.1, 1082.9 Bq kg(-1) and BDL, respectively. The total average absorbed dose rate owing to the presence of 232Th, 238U and 40K is found to be 3900.4 nGy h(-1). The annual effective dose is 4.7 mSv y(-1) and the results are discussed in this paper.
