摘要

摘要近年来，天然放射性物质（NORM）已成为环境保护领域的一个重要课题。随着国际立法的新修正案出台，环境中应监测的同位素清单不断增加。常被研究的NORM元素之一是210Po。本研究提出了一种测定土壤中210Po的新方法。在所提出的方法中，修改了几个分析方面，如二氧化硅分解的影响或电极材料的优化。所获得的程序允许在一天内进行完整的放射化学分析，化学效率超过85%，并大大降低了成本。此外，还证实了磷肥的使用对土壤中鎓浓度的影响。

Optimization of 210Po determination in soil

Abstract In recent years, naturally occurring radioactive materials (NORM) have become an important topic from the perspective of environmental protection. The list of isotopes that should be monitored in the environment is constantly growing as new amendments to international legislation are introduced. One of the often studied NORM elements is 210Po. In this study, a process of elaborating of a new method of 210Po determination in soil was presented. In the proposed method, several analytical aspects, like the influence of silica decomposition or optimization of an electrode material, were revised. The obtained procedure allows performance of complete radiochemical analysis in a single day, with the chemical efficiency of over 85% and great reduction of costs. Further, the influence of the use of phosphate fertilizers on polonium concentration in soil was also confirmed.
