Exposure Risks Assessment Due to Gamma Emitting Radionuclides in Soils and Consumable Waters Around Princess Gold Mine Dump in Roodepoort, South Africa

This study evaluated the activity concentration of 238 U, 226 Ra, 232 Th, and 40 K around the Princess Gold Mine dump in Roodepoort, South Africa using gamma spectrometry and ICP-MS. The soil contained a high concentration of 238 U at a depth of 1 m and at the surface. Doses due to ingestion of the...

Description
Summary:This study evaluated the activity concentration of 238 U, 226 Ra, 232 Th, and 40 K around the Princess Gold Mine dump in Roodepoort, South Africa using gamma spectrometry and ICP-MS. The soil contained a high concentration of 238 U at a depth of 1 m and at the surface. Doses due to ingestion of the untreated water were estimated as being far above the limit of 0.10 mSv/a set by the World Health Organization. The South African National Nuclear Regulator’s reference value of 0.25 mSv/a was also exceeded by almost all of the analyzed water samples. Thus, the dose the public could receive from drinking this water poses a potential radiological health risk.
