dc.description.abstract The concentrations of naturally occurring radionuclides 40K, 232Th and 238U in soil samples taken from the Neudamm campus of the University of Namibia, Windhoek, Namibia have been determined and used to calculate a mean annual effective dose for the campus. The concentrations were measured using a sensitive gamma-ray spectroscopic system consisting of a high purity germanium detector and associated equipment. 40K was found to have the highest specific concentration varying between 229.1 13.5 Bq kg􀀀1 and 499.0 16.5 Bq kg􀀀1 with a mean value of 364.5 79.3 Bq kg􀀀1 while the concentration of 232Th varies between 10.4 2.8 Bq kg􀀀1 and 38.5 3.8 Bq kg􀀀1 with a mean value of 28.0 9.2 Bq kg􀀀1 and the concentration of 238U varies between 11.7 1.3 Bq kg􀀀1 and 24.7 2.1 Bq kg􀀀1 with a mean value of 18.5 4.8 Bq kg􀀀1. The value of 0.05 0.01 mSv y􀀀1 obtained for the mean annual effective dose is well below the limit of 1 mSv y􀀀1 recommended for the public by the International Commission on Radiological Protection. This result indicates that radiation hazard is negligible on the campus. en_US
