Rapid determination of selected gross alpha and beta emitters in environmental matrices by solid-state scintillation technique is discussed. This method is based on sample treatment using microwave reactor and direct measurement of digested products using powder scintillator and alkaline solution as a substitute for traditional liquid scintillation cocktail. The selected group of radionuclides was chosen with respect to their use in nuclear industry, high radiotoxicity, and the possibility of potential misuse. The work aimed at verifying the connection of microwave decomposition using alkaline solution with solid-state scintillation using a powder scintillator YAP:Ce together with an alkaline medium.
本文讨论了通过固态闪烁技术快速测定环境基质中选定的总α和β发射体。该方法基于使用微波反应器进行样品处理，并使用粉末闪烁体和碱性溶液直接测量消化产物，以替代传统的液体闪烁鸡尾酒。选择这组放射性核素是考虑到它们在核工业中的用途、高放射性毒性以及潜在滥用的可能性。这项工作旨在验证使用碱性溶液的微波分解与使用粉末闪烁体YAP:Ce和碱性介质的固态闪烁之间的联系。
