Description
Summary:	Hair analysis presents a lot of advantages compared to the analysis of biological fluids or tissues. Hair of employers from the National (Brazilian) Nuclear Energy Commission (CNEN) was analyzed and compared with a control group. Samples were heated at 90°C with nitric acid, and diluted. Aliquot of these solutions was analyzed in ICP-MS. The concentration of U, Th, Pb and Zn were determined. Student t -test showed that there is no significant difference among the groups for all analyzed elements. The results demonstrated that men had more Pb than women. For Zn, the results showed that the levels are within the “normal” range, except for a woman that had her hair painted.
