Project Summary/Abstract - Discipline C: Radiochemistry Analytical Track 1: Food Defense The State Hygienic Laboratory’s (SHL) participation in this project contributes to the overall objective of the grant by maintaining and enhancing the capacity and capabilities of SHL to respond to foodborne radiological threats as part of an integrated food safety system. This project will strengthen and improve the collaboration on surveillance testing activities between the FDA and SHL, and contributes to building a nationally integrated laboratory science system, while increasing national food testing capacity for radiological threats. The specific aims of this project are to: 1. Conduct surveillance testing on 50 juice samples for gamma-emitting radionuclides. 2. Conduct gross alpha screening testing on 25 juice samples for alpha particle emissions. 3. Participate in FDA-requested triage exercises, and/or surveillance activities to support and maintain readiness. 4. Participate in national security event exercises, as available. 5. Maintain preparedness to rapidly respond to a suspected or confirmed intentional contamination event involving human food. This includes maintaining instruments and facilities, stocking reagents and supplies for emergencies, and training staff to perform analyses. SHL will collect juice samples and, during the first six months of the grant period, will analyze 25 samples for gamma-emitting radionuclides. In a concurrent project, SHL will also be implementing microwave digestion to improve its capacity to rapidly screen samples for alpha emitters. In the final six months of the grant period SHL will collect and analyze 25 juice samples for gamma-emitting radionuclides and screen these samples for alpha particles. This project is also be beneficial to SHL by improving its capability and capacity to analyze juice (and by extension, other sugary products), providing training opportunities for staff in radiological food analysis, and working on various processes with Iowa Department of Inspection and Appeals, including sample collection and chain of custody, which are crucial during foodborne threat events.

项目概要/摘要-学科C：放射化学 分析途径1：食品防御 国家卫生实验室（SHL）对该项目的参与有助于实现 维持和加强卫生及食物局应对食源性辐射的能力， 作为综合食品安全体系的一部分。该项目将加强和改善合作， FDA和SHL之间的监督测试活动，并有助于建立一个全国性的综合 在这方面，我们将继续努力，加强实验室科学系统，同时提高国家食品放射性威胁检测能力。 该项目的具体目标是： 1.对50个果汁样本进行伽马放射性核素监测测试。 2.对25个果汁样品进行α粒子排放的总α筛选测试。 3.参与FDA要求的分诊演习和/或监测活动，以支持和维护 准备就绪。 4.参加国家安全事件演习，如果可以的话。 5.随时准备对疑似或确认的故意污染事件做出快速反应 涉及人类食物。这包括维护仪器和设施，储存试剂和用品 紧急情况，并培训工作人员进行分析。 SHL将收集果汁样本，并在资助期的前六个月内分析25个样本， 伽马射线放射性核素在一个并行项目中，SHL还将实施微波消解， 提高其快速筛选α发射体样品的能力。在赠款期的最后六个月， SHL将收集和分析25个果汁样本的伽马放射性核素，并筛选这些样本， 阿尔法粒子 该项目也有利于SHL提高其分析果汁的能力（以及 （延伸，其他含糖产品），为放射性食品分析工作人员提供培训机会，以及 与爱荷华州检查和上诉部一起处理各种流程，包括样本收集 和监管链，这在食源性威胁事件中至关重要。
