Project Summary – Discipline C: Radiochemistry, Track 1 The New Jersey Department of Health (NJDOH) Public Health and Environmental Laboratories (PHEL) is pursuing the U.S. Food and Drug Administration (FDA)’s Laboratory Flexible Funding Model cooperative agreement focused on improving the capability and capacity of NJ to maintain food safety and security. The Radioanalytical Laboratory at NJDOH will prepare for triage exercises to support and maintain State and network readiness. Semi-quantitative instruments, such as portable field survey meters, will be used to scan potentially contaminated food samples. The semi-quantitative results will determine if contamination is “well above” or “well below” regulatory limits. To process samples in a timely and effective manner, the following analytical process flows will be followed: a) general screening based on total radiation emitted from the sample. b) screening based on type of radiation emitted (i.e., alpha, beta, or gamma). c) using radionuclide-specific analytical techniques to indicate the most significant activities or when the radionuclides have been identified. Additionally, the laboratory will support the network by participating in national security events and other emergency exercises as requested by FDA, maintaining surge capacity to analyze human food samples for the detection of gamma emitters, including but not limited to Cs-137, Cs-134, Co-60, Mn-54, Ru-103 and I-131, alpha emitters (U, Am, Pu, Th), and beta emitters (Sr-90). Laboratory staff will apply their experience working with vegetation, juices, grain products, seafood, dairy products, baby foods, water, other beverages, and other matrices to support the testing needs of the FDA. By conducting the work detailed in this proposal and managing an integrated food safety system, NJDOH will be able to expand its food defense and safety activities while further safeguarding public health. Importantly, the work conducted by PHEL will supplement the national efforts of the FDA and other states while providing our federal and State partners with critical radiological contaminant data they can use to enhance their food defense activities.

项目摘要-学科C：放射化学，轨道1 新泽西卫生部（NJDOH）公共卫生和环境实验室（PHEL） 美国食品和药物管理局（FDA）的实验室灵活资助模式合作 该协议的重点是提高新泽西州的能力和能力，以维护食品安全和保障。的 NJDOH的放射性分析实验室将准备进行分类演习，以支持和维护国家和网络 准备就绪。 半定量仪器，如便携式现场测量仪，将用于扫描潜在的 受污染的食物样本半定量结果将确定污染是“远高于”还是“远高于 低于”监管限制“。为了及时有效地处理样品，以下分析过程 将遵循以下流程：a）基于从样品发射的总辐射的一般筛选。B）基于筛选 取决于发射的辐射的类型（即，α、β或γ）。c）使用放射性核素特定分析技术， 表明最重要的活动或已查明放射性核素的时间。 此外，该实验室还将通过参与国家安全活动和其他活动来支持该网络。 根据FDA的要求进行紧急演习，保持分析人类食品样本的激增能力， 检测γ发射体，包括但不限于Cs-137、Cs-134、Co-60、Mn-54、Ru-103和I-131，α 发射体（U、Am、Pu、Th）和β发射体（Sr-90）。实验室工作人员将运用他们的工作经验， 蔬菜，果汁，谷物产品，海鲜，乳制品，婴儿食品，水，其他饮料和其他 矩阵，以支持FDA的测试需求。 通过开展本提案中详述的工作和管理综合食品安全系统，NJDOH将 能够扩大其食品防御和安全活动，同时进一步保障公众健康。重要的是 由PHEL进行的工作将补充FDA和其他州的国家努力，同时提供我们的 联邦和州的合作伙伴，他们可以使用关键的放射性污染物数据来加强他们的食品防御 活动
