Studies indicate that early identification of persons involved in and receiving high doses of radiation in accidents is key to providing life-saving medical treatment. Although the risk of criticality accidents is low, the potential impact to workers is significant. For facilities that employ large numbers of workers, a key element in the response to a radiological emergency is identifying personnel that received significant and potentially harmful doses. Also important is having the ability to screen large numbers of workers to identify persons who did not receive significant exposure so as to reduce the impact on emergency response efforts. At the Y-12 National Security Complex, the focus on criticality accident response is the rapid triage of personnel in order to identify persons exposed to large radiation doses and to prioritize those persons receiving the highest exposures. Once identified, personnel are transported to local medical facilities, including the Radiation Emergency Assistance Center/Training Site (REAC/TS), for medical evaluation and treatment. The Y-12 external dosimetry program uses a number of techniques to identify and prioritize workers, and these methods were evaluated at a criticality dosimetry intercomparison exercise. The methods used were shown to perform as intended, and other sites may consider incorporating these methods into their accident dosimetry response procedures.

危重事故分类方法的评估。

研究表明，及早识别事故中涉及和接受高剂量辐射的人员是提供救生医疗的关键。尽管临界事故的风险很低，但对工人的潜在影响却很大。对于雇用大量工人的设施，应对放射紧急情况的一个关键要素是识别受到大量和潜在有害剂量的人员。同样重要的是有能力对大量工人进行筛查，以识别未受到大量暴露的人员，从而减少对应急响应工作的影响。在 Y-12 国家安全综合大楼，对临界事故响应的重点是对人员进行快速分类，以确定暴露于大辐射剂量的人员，并优先考虑那些受到最高照射的人员。一旦确定，人员将被运送到当地医疗设施，包括辐射紧急援助中心/培训中心 (REAC/TS)，进行医疗评估和治疗。Y-12 外部剂量测定计划使用多种技术来识别工人并确定其优先顺序，这些方法在临界剂量测定比对练习中进行了评估。使用的方法已按预期执行，其他站点可能会考虑将这些方法纳入其事故剂量测定响应程序。包括辐射紧急援助中心/培训中心 (REAC/TS)，用于医疗评估和治疗。Y-12 外部剂量测定计划使用多种技术来识别工人并确定其优先顺序，这些方法在临界剂量测定比对练习中进行了评估。使用的方法已按预期执行，其他站点可能会考虑将这些方法纳入其事故剂量测定响应程序。包括辐射紧急援助中心/培训中心 (REAC/TS)，用于医疗评估和治疗。Y-12 外部剂量测定计划使用多种技术来识别工人并确定其优先顺序，这些方法在临界剂量测定比对练习中进行了评估。使用的方法已按预期执行，其他站点可能会考虑将这些方法纳入其事故剂量测定响应程序。
