Abstract: A procedure for determination of cobalt in biological materials using the short-lived induced radionuclide 60mCo is described. 60mCo has been rarely used as an indicator radionuclide in NAA due to low concentrations usually found in biological materials and due to its short-half life (t1/2 = 10.5 min). Using the described procedure, based on dissolution of the irradiated sample, precipitation of Co with C5H10NNaS2*3H2O, extraction of the complexes formed into toluene, purification and counting by gamma spectrometry, Co was determined in biological materials at ng g-1 levels.
