Method for determination of uranium isotopes in various environmental samples is presented. The major advantages of the method are the low cost of the analysis, high radiochemical yields and good decontamination factors from the matrix elements, natural and man-made radionuclides. The separation and purification of uranium is attained by adsorption with strong base anion exchange resin in sulfuric and hydrochloric acid media. Uranium is electrodeposited on a stainless steel disk and measured by alpha spectrometry. The analytical method has been applied for the determination of concentrations of uranium isotopes in mineral, spring and tap waters from Bulgaria. The analytical quality was checked by analyzing reference materials.
介绍了测定各种环境样品中铀同位素的方法。该方法的主要优点是分析成本低、放射化学产率高以及对基体元素、天然和人造放射性核素的去污系数良好。在硫酸和盐酸介质中，通过强碱性阴离子交换树脂吸附实现铀的分离和纯化。铀电沉积在不锈钢圆盘上，并用α能谱法进行测量。该分析方法已应用于测定保加利亚矿泉水、泉水和自来水中铀同位素的浓度。通过分析参考物质来检查分析质量。
