[en] A study of an aboriginal community was conducted to determine if kidney function had been affected by the chronic ingestion of uranium in drinking water from drilled wells whose uranium concentrations varied from <1 to 1,418 ppb. This non-invasive study relied on the measurement of a combination of indicators of kidney function and markers for cell toxicity measured in urine samples collected from 39 females and 15 males. Ages ranged from 12 to 73 years. Correlation of uranium excreted in urine with bio-indicators at p≤0.05 indicates interference with the kidney's reabsorptive function. Because of the community's concerns regarding cancer incidence, cumulative radiaiton doses were also calculated using uranium intake in drinking water over the preceding 15-year period. the average dose was 0.2 mSv and the highest dose, 1.7 mSv with the risk of cancer from the former being 1.4 in 100,000 while that from the latter in 12 in 100,000. Both would be difficult to detect in the community studied (population: 1,480). (Author) 28 refs
