Tin mining and processing in Nigeria: cause for concern

Jan 01, 2003· 2. Materials and methods. At the Jos Plateau, Nigeria (), portable survey meters (a 2.5-cm × 2.5-cm NaI(Tl) detector and an Atomtex dosimeter) were used for in-situ radiation measurements in the field.Three sites at the tin mine were surveyed to identify study locations. A tailing dump ground showed highest values and thus was chosen to represent the site most at risk (i.e., worst case).
