Abstract:
:Uptake of 226Ra, 232Th, 230Th, and 228Th from water, sediment, and diet sources to bone and muscle of white suckers (Catostomus commersoni) was studied in sixteen lakes in the uranium-mining district of Ontario, Canada. Fish tissues did not increase linearly with environmental concentrations. The best relationship appears to be a power function. This has implications for the accuracy of radiological dose and risk estimates for uranium mining impacts, which are often based on a linear model.

HEALTH PHYSICS文献大全abstract::The escaping radioactivity from Greek coal power plants (CPP) was studied. For the case studied the radioactivity is due to the uranium series. The major part (99%) escapes as very fine particles, while the rest is fly ash. The total escaping 226Ra activity is of the order of 40 Ci/yr. The particulate dispersion of fl...
