Sažetak
In the present study, the activity concentrations of 226Ra, 232Th, 40K in steel slags generated during the production of low carbon steel in the CMC Sisak Steel Mill has been investigated using gamma spectroscopy technique and mathematical models. The radionuclide activity concentrations of 226Ra, 232Th and 40K, activities index (I1, I2, I3) and radium equivalent concentrations (Raeq) of steel slags were determined in order to assess the radiological hazards from steel slags due to the their utilization as raw materials in building industry. The measured activities concentrations of 226Ra, 232Th, 40K in electric arc furnace slag and ladle furnace slag are significantly lower than the maximum Croatian allowed limit so investigated slags, in terms of the radionuclides present, may be applied as raw materials and/or additives in the construction industry. Activities index (I1, I2, I3) calculated on the basis of measured radionuclide activity concentrations of 226Ra, 232Th and 40K were less than 1, i.e. it shows that neither of the examined slags samples exceeds values recommended by the Nuclear Safety Authority (STUK) Guide ST 12.2 and Croatian Ordinance.
