Abstract/OtherAbstract:
Recent reviews have highlighted the diversity (and sparsity) of data for uranium concentrations in body fluids, bone and soft tissues, and it is unclear to what extent this reflects genuine geographical or biological variations. In the present work, a very sensitive radiochemical neutron activation analysis technique (detection limit, 1-2pg g-1) was applied to an exploratory study of uranium levels in hair, urine and blood of non-exposed and occupationally exposed persons. Since quality control in much previous work has been somewhat neglected, this aspect was emphasized by the use of a wide range of suitable reference materials, by standard addition experiments, and by care in sampling and sample handling. For controls, typical levels found in hair, urine and blood were 10 ng g-1, 10 and 5 ng l-1, respectively. The urine values correspond to the lower end of the literature data, while for blood our value is about two orders of magnitude lower than the presently quoted level. In the case of occupationally exposed persons, it was found that hair shows some promise as an indicator of exposure.
