Description
An assessment of the radiation concentration in abandoned mines located near settlements in the west of Johannesburg was carried out, and the corresponding radiological indices were determined. In this study, a gamma spectrometer was used to measure the activity concentrations of radionuclides in the soil samples. The activity concentrations for 226Ra, 232Th, and 40K were 338.44±3.48, 10.06±0.68, and 126.15±10.90 Bq/kg, respectively. The results revealed that the average activity concentrations at some locations exceeded the world average for some of these nuclides.
