In: INTERNATIONAL CONFERENCE ON METHODS AND APPLICATIONS OF RADIOANALYTICAL CHEMISTRY, 5th, Apr. 9-14, 2000, Kailua-Kona, HI, USA. <b>Proceedings...</b> Disponível em: http://repositorio.ipen.br/handle/123456789/13995.http://repositorio.ipen.br/handle/123456789/13995In this work instrumental neutron activation analysis was applied to determine trace elements in nail clippings and to make a comparison between the results obtained from samples from healthy children and those with cystic fibrosis (CF) disease. The findings indicated that fingernails from the CF group present higher concentrations of Cl, Cr, K and Na than those found in the control group. On the other hand, the lowest concentrations for Cr were found in the CF group. For the Al, As, Co, Fe, Mg, Mn, Se and Zn elements there were no differences between the results obtained for the CF and control groups. The quality control of the results was evaluated by analysing NIST 1577b Bovine Liver and NIST 1566a Oyster Tissue standard reference materials.openAccessneutron activation analysisnailselementstrace amountsmulti-element analysischildrenfibrosispatientscomparative evaluationsTexto completo de evento
