الملخص
Since its creation, the earth has always been bathed in a cocktail of natural radioactivity.Its content varies from location to another and from depth to another. Radiations arisen fromthese radionuclides constitutes hazard to human health. Therefore the radioactivitymeasurement is necessary to evaluate the effects of these radiations.In the recent years, many studies give an importance to activity concentrationmeasurements of natural radionuclides in sediment which plays an important role in aquaticecosystems. It is considered the main source of continuous radiation exposure of human andas considered a medium of migration for the transfer of radionuclides to the biologicalsystems.The aim of the present work is to study the distribution of natural radioactivity in BeniHaroun dam; the largest dam in Algeria. For this reason, sediment samples collected fromdifferent locations in this dam and from rivers feeding it. Activity concentrationmeasurements of natural radionuclides in these samples were carried out using a high puritygermanium detector (HPGe).The 226Ra, 232Th and 40K mean activity were found to be 23.48 ± 3.85, 23.48±14.03 and196.28± 31.00 Bq/kg, respectively. Also, radiological hazard parameters due to thesesediment samples were estimated based on these specific activities. Finally, the results of thepresent study were discussed and compared with internationally recommended values.
