Levels and effects of natural radionuclides in sediment banks of Rhumel River (Northeast Algeria)
Abstract
Activity
concentrations of natural radionuclides in Boumerzoug River sediment (the main
tributary of Rhumel river) have been measured using high resolution HPGe
detector. The activity concentrations of the samples were range from 16.66±2.32 Bq/kg to 43.48±4.03 Bq/kg with mean value of 26.64±1.33 Bq/kg for 226Ra, 20.01±1.98 Bq/kg to 32.71±3.85 Bq/kg with the mean value 25.95±1.46 Bq/kg for 232Th and 81.70±33.59 Bq/kg to 259.20±38.80 Bq/kg with the mean value
164.50±11.30 Bq/kg for 40K. These values were used to
estimate the radiation hazard indices. The absorbed dose and annual effective
dose were evaluated to assess the radiation risk due to the use of these
sediments.
