Sažetak
Nuclide 90Sr is one of twelve radioactive isotopes of strontium that has an artificial origin as a consequence of nuclear weapon testing during 1950s and 1960s, as well as the nuclear accidents. Based on its half-life of 28.8 y, this radionuclide can still be found in the environment as a result of these activities. The knowledge about behavior of 90Sr and also of its content in environmental samples is of extreme importance to prevent and control contamination, predominantly of food chain. For the purpose of this study, an agricultural soil from territory of the Republic of Serbia was investigated. The aim was to compare three different methodologies for the determination of 90Sr activity in soil samples and the interpretation of obtained results. The radiochemical analytical method of 90Sr determination via 90Y, radiochemical analytical method based on ion-exchange resins and radiochemical analytical method with fuming nitric acid were compared and evaluated. In all cases measurements were performed on proportional counter. The acquired results showed a good agreement between the compared methods.
