This paper describes the impact of renal threshold concentrations for uranium; the latest biokinetic models recommended by the International Commission on Radiological Protection; and the pattern of exposure on intake limits and their assessment. It is concluded that the current daily limit on intake of 2 mg is acceptable, but considerable uncertainties exist in assessment from urine analysis. It is suggested that the role of biochemical indicators of exposure should be pursued.
