Abstract

The k 0 parametric neutron activation analysis has been applied since 1995 in the Radiochemical Sector/CDTN, Belo Horizonte, Brazil. Several certified reference materials were studied with the aim of analysing biological samples. This work is related to an IAEA co-ordinated research project whose goal is to make a survey of the exposures to metals related to occupational diseases. It has been conducted by CDTN and government departments of health. The hair samples as bioindicators were donated by galvanising factory workers in Belo Horizonte. This city and surrounding area are important industrial centres and that industry is responsible for the majority of patients who look for medical assistance because of metal contamination. The Al, Co, Cu, Cr, La, Mn, Sb and V concentrations determined in the workers' samples suggest endogenous contamination.
