o:16718 Optimizacija konverzionih modela za izračunavanje intenziteta erozije zemljišta na osnovu aktivnosti radioizotopa 137Cs doktorska disertacija Optimization of conversion models for the calculation of the intensity of soil erosion based on activities of radioisotope 137cs : doctoral dissertation sr U radu je ispitana mogućnost primene konverzionih modela za ispitivanje intenziteta erozije neobrađivanog zemljišta korišćenjem radioizotopa 137Cs. Neki razvijeni konverzioni modeli optimizovani su za potrebe primene na istraživanom prostoru male površine gde je černobiljska depozicija dominantna, odnosno za izračunavanje srednjeg godišnjeg intenziteta erozije zemljišta za period od 1986. do 2014. godine (godine uzorkovanja)... This study examines the possibility of implementation of conversion models to estimate the soil erosion and deposition rates for uncultivated area using environmental radionuclide inventories of 137Cs. To obtain quantitative estimates of the average annual soil redistribution rates over the period from 1986 and sampling year (2014), from radionuclide measurements in the small study area with 137Cs input predominantly from Chernobyl accident (1986), some of conversion models have been modified...
