AB - An analytical method is described for the estimation of uranium concentrations, of U-235/U-238 and U-236/U-238 isotope ratios and burn-up of irradiated reactor uranium in contaminated soil samples by inductively coupled plasma mass spectrometry. Experimental results obtained at 12 sampling sites situated on northern and western radioactive fallout tails 4 to 53 km distant from Chernobyl nuclear power plant (NPP) are presented. Concentrations of irradiated uranium in the upper 0-10cm soil layers at the investigated sampling sites varied from 2.1 x 10(-9) g/g to 2.0 x 10(-6) /g depending mainly on the distance from Chernobyl NPP. A slight variation of the degree of burn-up of spent reactor uranium was revealed by analyzing U-235/U-238 U and U-236/U-211 isotope ratios and the average value amounted to 9.4 +/- 0.3 MWd/(kg, U).
