Radionuclides in metallurgical products and waste

This article presents the results of radionuclide distribution in electric arc furnace process of steel production. Input materials, products and technological waste (slag and dust) are analysed. The presence of natural isotopes 40-K, 226-Ra, 232-Th, and 238-U as well as of the artificial isotope 137-Cs was established. Paper shows that 40-K and 137-Cs will be concentrated in dust, 226-Ra and 238-U will be mainly distributed between dust and slag but their presence in steel cannot be excluded. 226-Ra and 238-U in steel, slag and dust mainly come from fluorspar and bauxite. 232-Th was not detected in raw materioals and steel scrap but it was concentrated in slag and dust during the technological process. The measured activity in dust and slag, both artificial and natural isotopes lie within the legally permitted limits.
