Abstract
Concentrations of uranium in several brands of di-calcium phosphate commercialized in Brazil were measured by means of a recently developed electrofission/SSNTD technique. These results, plus the alimentary habits of brazilian consumers, allowed to estimate the radiation exposure. Calculations of internally localized doses (“hot spots”) were worked out and some aspects of radiobiological effects and risks were addressed.
