| Popis: | This study evaluated the activity concentration of 238U, 226Ra, 232Th, and 40K around the Princess Gold Mine dump in Roodepoort, South Africa using gamma spectrometry and ICP-MS. The soil contained a high concentration of 238U 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. |
