Radionuclides in Food - Food Defense and Emergency Analysis

项目摘要-学科C：放射化学，轨道1 新泽西州卫生部(NJDOH)公共卫生和环境实验室(PHEL) 推行美国食品药品监督管理局S实验室灵活筹资模式合作 协议的重点是提高新泽西州维护食品安全和保障的能力。这个 NJDOH的放射分析实验室将为分流演习做准备，以支持和维护国家和网络 准备好了。 半定量工具，如便携式现场勘测仪，将用于潜在的扫描 受污染的食物样本。半定量的结果将决定污染程度是“远高于”还是“良好”。 低于“监管限制”。为了及时和有效地处理样品，以下分析过程 将遵循以下流程：a)根据样品发出的总辐射进行一般筛查。B)基于筛选的 关于发射的辐射类型(即，阿尔法、贝塔或伽马)。C)利用放射性核素特有的分析技术 指明最重要的活动或确定放射性核素的时间。 此外，该实验室将通过参加国家安全活动和其他活动来支持该网络 按照FDA的要求进行紧急演习，保持分析人类食物样本的突击能力 探测伽马发射体，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)和贝塔发射体(锶-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、其他饮料等 支持FDA检测需求的矩阵。 通过开展本提案中详细说明的工作并管理一个综合的食品安全体系，NJDOH将 能够在进一步保障公众健康的同时，扩大其食品防御和安全活动。重要的是， 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 联邦和州合作伙伴拥有关键的放射性污染物数据，可以用来加强他们的食品防御 活动。

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.
