[email protected]) Abstract- Naturally occurring radioactivity measurement, radionuclides in soil samples of the study area is necessary as radiation monitoring of the region, dose assessment and the data produced in this paper may be used as baseline data interpretation of radiological related parameters are crucial for future environmental assessments. The present study aspects from the public awareness and environmental safety estimates the external gamma dose rate, which creates a public point of view. The ionizing radiations (γ-rays) emitted from awareness about the radiation and provides the necessary radionuclides such as 226Ra, 232Th and 40K present in environmental materials contributes significantly to the radiation information about the radiological protection. dose received by the public. Gamma spectrometry based high efficiency 4"X4" NaI(Tl) detector was employed for estimating activity concentrations of the gamma emitting radioelements. II Study Area The spectra from the detector were recorded using a PC based The study has been carried out over two talukas of the Raichur 1k multichannel analyzer system (WinTMCA 32). Each sample district namely Devadurga and Lingasugur, covering an spectra was acquired for a counting period of 60,000 sec (16.67 approximate area of 2500 square kilometers between 16.02, 226 232 h).
