摘要

美国疾病控制和预防中心（CDC）辐射实验室的主要任务是为有效和高效地应对公共卫生辐射紧急情况提供实验室支持。该实验室已开发出针对包括铱-192（Ir-192）在内的多种放射性威胁物剂的方法。Ir-192 可以通过高纯锗（HPGe）等分析方法分析其伽马能量，也可以通过液体闪烁计数（LSC）分析其β能量。在这项工作中，我们介绍并比较了用于 Ir-192 定量的 HPGe 和 LSC 快速反应方法。两种方法都显示出合理的结果，可用于紧急情况。

Analytical methods for Ir-192 determination and their comparison

The Centers for Disease Control and Prevention (CDC) Radiation Laboratory’s primary mission is to provide laboratory support for an effective and efficient response to public health radiological emergencies. The laboratory has developed methods for several radiological threat agents, including Iridium-192 (Ir-192). Ir-192 can be analyzed via its gamma energy through analytical methods such as High Purity Germanium (HPGe) and its beta energy through Liquid Scintillation Counting (LSC). In this work, we present and compare HPGe and LSC rapid response methods for Ir-192 quantification. Both methods show the reasonable results and can be used in emergency situations.
