Abstract

Absorbed dose rate and natural radionuclide activity concentration measurements were performed to determine the elevation in natural radionuclides, primarily uranium, caused by use of the ammunition with depleted uranium during NATO strikes at targets in the municipality Hadzici in 1995. Assessment of the DU presence was based on the quantification of uranium/radium disequilibrium and statistical analysis of the obtained results compared with results from previous studies. Elevated levels of 238U with high238U /226Ra disequilibrium which were recorded at several points as well as the irregular distribution of activity concentrations of 238U and 226Ra along the two observed soil profiles implied the possible presence of DU. The obtained results pointed out on the possible use of described method for assessment of depleted uranium presence in soil at points at which the ammunition with DU had been used. The described method could be used together with methods for quantitative-qualitative determination of DU.
