Abstract

In this study there are determined the levels of radiation doses to non enhanced materials (raw material) and the changing level of these doses of radiation after the technological enhances of the materials, respectively NORM (Naturally Occurring Radioactive Material) & TENORM (Technologically Enhanced Naturally Occurring Radioactive Material). The directly field measurements are conducted by the detectors: Gamma spectrometer Gr-130; Inspector–EXP-Radiation Alert, TA-PUG-7A and Gama monitor- SGM-29-246. The field measurements indicate that the level of radiation dose of the natural background, raw material (ore, lignite and limestone) and residues (Converter slag, Electro filter dust, Slag from electric furnace and Sludge from electric converter gas scrubber) are from 75.00 nSv/h to 110.00 nSv/h. Then samples from the field are treated in terms of physic-chemical aspect in the Centre of Applied Nuclear Physics in Tirana, where are determined the radionuclide’s and also is determined the concentration of radiation, respectively in the laboratory of Gamma Spectrometry with Gamma instrument spectrometer - CANBERRA It is determined the Radionuclide and specific activity from Converter slag residues [Bq/kg] and the specific activity Gamma Total.
