As part of the Centers for Disease Control and Prevention's post-radiological/nuclear incident response mission, we developed rapid bioassay analytical methods to assess possible human exposure to radionuclides and internal contamination. Liquid scintillation counting (LSC) is a valuable analytical tool for the rapid detection and quantification of gross alpha/beta-emitting radionuclides in urine samples. A key characteristic of this type of bioassay method is its detection sensitivity for the priority threat radionuclides. We evaluated the limit of detection of selected LSC instruments to determine which instrument can be used when low-dose measurement is important.
作为美国疾病控制与预防中心放射/核事件后应对任务的一部分，我们开发了快速生物测定分析方法，以评估人类可能接触放射性核素的情况及体内污染状况。液体闪烁计数法（LSC）是一种用于快速检测和定量尿液样本中总α/β发射放射性核素的重要分析工具。这类生物测定方法的一个关键特性是其对优先威胁放射性核素的检测灵敏度。我们评估了选定的液体闪烁计数仪的检测限，以确定在低剂量测量很重要时可使用哪种仪器。
