Revisiting a case study on uranium exposure linked to leukaemia – preliminary results

Triggered by observations that a disproportionally high number of leukaemia patients came from a particular area around the small town of Pofadder in the arid Northern Cape Province, a subsequently conducted research project established a geo-statistical link between naturally elevated U-levels in groundwater and haematological abnormalities. In this paper results from a follow-up study are presented indicating the water is indeed the most important pathway for U-exposure while consumption of contaminated sheep meat also contributes but to a lesser extent.
