Abstract

© 2015. Activity concentrations of soil and sand samples from southern part of Kuwait have been deduced for members of the 238U(226Ra) and 232Th(228Ac) decay chains, together with initial evaluations also provided of the concentrations for members of the 235U, 4n+1 chain. Additional activity concentration measurements have also been established for the single primordial radionuclide 40K and the anthropogenic radionuclides 137Cs from the same samples. The calculated activity concentration values and associated radiation hazard indices calculated were evaluated. The current results indicate activity concentrations ranging from 0.15±0.04 to 9.97±0.20Bq/kg for Cs. For 226Ra, 232Th and 40K this ranges from 9.02±0.13 to 17.48±0.18, 7.90±0.10 to 14.29±0.22, and 259.6±4.7 137Cs to 347.3±6.0Bq/kg, respectively. The mean values for dose rates, radium equivalent, hazard indices, and annual effective dose equivalent are 24.65±0.26nG/h, 50.72±0.50Bq/kg, 0.17, 0.14, and 30.0±0.3μSv/yr, respectively. These are compared with analogous measurements from other locations both in the Middle Eastern Region and far-afield.
