Sažetak
Because natural and artificial isotopes in steel might originate from steel scrap or from the residue of the material that was used in the technological process, thus monitoring especially artificial radionuclides 60Co, 137Cs and 192Ir deserve special attention. The analysis by -spectrometry has been applied to determine the presence of natural isotopes 40K, 226Ra, 232Th and 238U as well as of the artificial isotope 60Co, 137Cs and 192Ir and their activity in the produced steel round blooms in the Steel Mill of CMC Sisak d.o.o. At the same time the content of radionuclides in the electric arc furnace by-products (dust and slag) were determined, as well as in other materials (ferro-alloys, bauxite, fluor-spar, lime, coke, graphite electrodes, refractory blocks) used in the same steel making process. The measured values regarding the presence of individual isotopes and their activity in steel were as follows: 40K all values were less then 1.74 Bqkg-1 ; 232Th all activities values were less then 0.023 Bqkg-1 ; 226Ra all activities values were less then 0.013 Bqkg-1 ; 238U all activities values were less then 1.10 Bqkg-1 ; 60Co all activities values were less then 0.02 Bqkg-1 ; 192Ir all activities values were less then 0.02 Bqkg-1 and 137Cs all activities values were less then 0.30 Bqkg-1.
