项目摘要/摘要-学科C：放射化学 分析轨道2：放射化学能力/能力发展(阿尔法扩展) 国家卫生实验室(SHL)参与该项目有助于实现国家卫生实验室的总体目标 通过加强爱荷华州卫生实验室(SHL)的能力和能力来应对 食源性辐射威胁作为综合食品安全系统的一部分，通过扩大SHL的快速 对各种食品进行阿尔法放射性核素的筛查。鉴于SHL目前的量化能力 对离散的阿尔法发射体进行分析，这种增强的筛查能力将有助于SHL分流样本和 加快食品中阿尔法放射性核素的定性和定量分析 放射紧急情况。 该项目的具体目标是： 1.购买微波消解系统和额外的气流正比计数检测器，以 启用FERN-RAD.0003.00的性能，快速溶解液体有机基质 粗大α粒子分析的准备工作。 2.扩展食品列表，以便能够通过B级验证在SHL进行FERN-RAD.0003.00分析 对多种固体食品的研究。 3.培训指定的工作人员使用FERN-RAD.003.00分析食物中的粗大α粒子。 4.通过由合适的能力测试计划提供的能力测试来证明能力， 或者，如果不可用，则由实验室进行能力测试。 5.参加LFFM年度面对面会议。 在授权期的前六个月，SHL将采购、安装和优化一套微波消化系统， 并实现FERN.0003.00方法。律政司司长亦会在首个月内完成对员工的这项方法的培训。 六个月的授权期。在资助期的最后六个月，SHL将对25种果汁进行毛利率筛选 α粒子和执行蕨类B级验证研究五种固体食物类型，以增加SHL 筛选能力。该项目的成功完成将有助于FDA加强其全国一体化 食品安全体系，并将加强检测、预防和最大限度减少食源性暴露的努力。这 该项目还通过提高样品制备和分析能力以及提供 为工作人员提供样品制备技术和方法验证方面的培训机会。

Project Summary/Abstract - Discipline C: Radiochemistry Analytical Track 2: Radiochemistry Capacity/Capability Development (Alpha Expansion) The State Hygienic Laboratory’s (SHL) participation in this project contributes to the overall objective of the grant by enhancing the capacity and capabilities of Iowa’s State Hygienic Laboratory (SHL) to respond to foodborne radiological threats as part of an integrated food safety system by expanding SHL’s ability to quickly screen a variety food products for alpha-emitting radionuclides. Given SHL’s current ability to quantitatively analyze for discrete alpha-emitters, this enhanced screening capacity will help SHL triage samples and expedite both qualitative and quantitative analysis of food products for alpha-emitting radionuclides in a radiological emergency. The specific aims of this project are to: 1. Purchase a microwave digestion system and additional gas-flow proportional counting detectors to enable the performance of the FERN-RAD.0003.00, Rapid dissolution of liquid organic matrices in preparation for gross alpha particle analysis. 2. Expand the list of foods to able to be analyzed at SHL by FERN-RAD.0003.00 via Level B validation studies on a variety of solid food products. 3. Train designated staff in the analysis of foods for gross alpha particles via FERN-RAD.003.00. 4. Demonstrate competency through a proficiency test offered by a suitable proficiency testing program, or if unavailable, a laboratory developed competency exercise. 5. Attend the annual LFFM Face-to-Face Meeting. In the first six months of the grant period SHL will procure, install, and optimize a microwave digestion system, and implement the FERN.0003.00 method. SHL will also complete training of staff on this method in the first six months of the grant period. In the last six months of the grant period, SHL will screen 25 juice for gross alpha particles and perform FERN Level B validation studies on five solid food types to increase SHL’s screening capacity. Successful completion of this project will help the FDA enhance its nationally integrated food safety system and will strengthen its efforts to detect, prevent, and minimize foodborne exposures. This project is also be beneficial to SHL by enhancing its sample preparation and analytical capacity and providing a training opportunity for staff in sample preparation techniques and method validations.
