>The interpretation of data on uranium content in urine samples is discussed in the light of calculations based on human and animal experiments. In the case of insoluble uranium compounds, the critical hazard is radiological exposure of the lungs. With soluble compounds of highly enriched uranium the primary hazard is also radiological, due to the slow removal of uranium which is deposited in bone; for soluble compounds of highly enriched uranium the critical organ is therefore the bone, not the kidney. It is suggested that for these radiological cases the degree of hazard is best assessed by estimations of the chronicallyretained body burden by reference to after-holiday or afterweekend samples, not to shift samples. Maximum permissible urine concentrations recommended for after-holiday samples were calculated from ICRP parameters; the figures for the cases of soluble and insoluble uranium are almost identical. The relationship between urinary excretion and retained body burden for periods of up to 30 days after a single intake of uranium was also calculated directly from observations on human metabolism of uranium. For a given urinary excretion, the estimates are lower than those for the chronically retained body burden, as calculated from ICRP parameters. (auth)
