Description	Hladiny esenciálních prvků selenu a železa, které mají důležitou úlohu ve struktuře a funkci erytrocytů, byly stanoveny instrumentální neutronovou aktivační analýzou (INAA) s využitím samoověřovacího principu. Hladiny selenu se pohybovaly v rozmezí 167-317 ng/ml, zatímco u železa bylo zjištěno rozpětí 782 – 888 ?g/ml. Správnost výsledků byla prokázána analýzou dvou referenčních materiálů s podobných složením matrice a s podobnými obsahy analytů. (cs) Levels of two essential elements playing crucial roles in erythrocyte`s structure and functions, iron and selenium, have been carefully determined in 36 erythrocyte samples drawn from two healthy Nigerian subjects. The samples were obtained at different times of the day and under varied dietary conditions over a three-week period.Normal variations that could occur in the levels of these elements within a given healthy individual could then be established. Analyses of the samples were carried out by Instrumental Neutron Activation Analysis using for each element, two different sefl-validating procedures. For selenium, the short-lived isotope 77mSe (half-live of 7.5s), and the long-lived isotope 75Se (half-life of 120d) were used; while for iron the two gamma lines at 1099.2 keV and 1291.6 keV from the reaction 58Fe(n,gamma)59Fe were used. For each element, the results obtained from the two procedures were first compared.
