In the paper there are presented the outcomes of determining the radiation of some remaining of radionuclide from raw material in the technologic aspect (TENORM-Technologically Enhanced Naturally Occurring Radioactive Materials),in some industrial plants in Kosovo, particularly in Feronikel and Power Plant Kosova-B. On-site measurements were carried out by detectors: Gamma Spectrometer Gr-130; Inspector–EXP-Radiation Alert, Spectrometer- TA-PUG-7A as well as Gamma monitor- SGM-29-246. Samples were taken at the above-mentioned locations and they were treated in the physic-chemical aspect at the Centre for Applied Nuclear Physics in Tirana. On-site measurements, respectively at the centers: Feronikel-Drenas, Trepçë – Mitrovica and TEC (PP) – Obiliq show that the level of annual radiation is around the interval from 75.45 nSv/h to the values 289.54 nSv/h. By spectrometric analysis conducted at the Centre for Applied Nuclear Physics in Tirana, the following radionuclide and its radiation concentration, expressed in Bq/kg: Waste from the convertor of industrial compound Feronikel – Drenas. Radioactive elements and their concentration (Bq/kg) :K–40--37 + 7 Bq/kg; Ra–226--17 + 4 Bq/kg; Ra–228--6 + 1 Bq/kg; Th–228--5 + 1; Th–232--5 + 1 Bq/kg; U–238 --10 + 3Bq/kg. Waste from phosphogypsum, industrial compound Trepça –Mitrovica. K-40--10 + 3 Bq/kg; Ra–226-- 230 + 30 Bq/kg; Ra –228--5+ 1Bq/kg; Th –228--5 + 1Bq/kg; Th–232-- 5 + 1 Bq/kg; U–238-- 30 + 5Bq/kg Ash waste from the Power Plant Kosova B- Obiliq- radioactive elements and concentration (Bq/kg) K–40 -- 150 + 15 Bq/kg; Ra–226 -- 40 + 10 Bq/kg; Ra–228 -- 20 + 2Bq/kg; Th–228--20 +2;Th–232-- 20 + 2 Bq/kg; U–238-- 25 + 5 Bq/kg. Based on the outcomes of measurements, it can be concluded that in two locations Feronikel-Drenas and PP – Obiliq the level is lower than the average of the natural background (200-250 nSv/Yr). Whereas in the location of Trepça-Mitrovica there are higher values and this is an indication that it requires a further and detailed study approach. After the final assessment we will conclude whether such waste can be used in practice for various needs. It will be concluded that what is the risk introduced by such waste in the aspect of radioactive contamination of living environment.
