The research program is in radiation detection techniques, dosimetry, field characterization and safety hat, although no deaths are attributed or expected to be attributed to radioactive releases from the accident, over 1600 deaths have been attributed to evacuation stress caused by radiation fears. Indeed, rapid assessment of radiation fields post-accident and determination of potential for exposure can yield data that is of vital use to emergency response personnel. Since ionizing radiation cannot be detected through humans' five senses, instrumentation is required to rapidly understand and quantify the potential hazards. The research program is constructed from a number of research areas, presented as (1) development of field-portable instrumentation and techniques for rapid assessment of radiation fields and exposure (detector technologies such as cadmium zinc telluride semiconductor detectors, Geiger-Muller gas filled counters, zinc sulfide scintillation detectors, optically stimulated luminescent materials and electron paramagnetic resonance materials), (2) experimental investigation, modeling and quantification of radiation fields of significance to the program (aerosol dispersion, computational fluid dynamics and Monte Carlo modeling), and (3) exploring security issues as related to radioactive material use and misuse, with the emphasis of determining vulnerabilities and better integration with safety functions (synthetic environment and serious game simulation). The program is designed to train highly qualified personnel (undergraduate, master, doctoral and post-doctoral) in the areas of radiation detection, measurement and analysis, internal and external dosimetry, radiation field characterization, emergency preparedness, response and countermeasures, and safety and security of nuclear and radiological materials. The research will have great significance to the health physics and emergency response communities, as well as industrial and government agencies that have requirements to protect personnel. The research will benefit the scientific community by adding to the knowledge base of rapid radiation field characterization, phenomenology of aerosol behavior, in-field and retrospective dose assessment and security vulnerabilities, and by training a number of highly qualified personnel, many of whom will continue in research.

该研究计划是在辐射检测技术，剂量法，现场表征和安全性帽子中，尽管没有死亡归因于事故中的放射性释放或预期，但已有1600多人死亡归因于辐射恐惧引起的撤离压力。 实际上，对媒体后的辐射场的快速评估和暴露潜力的确定可以产生对应急人员至关重要的数据。 由于无法通过人类的五种感觉检测到电离辐射，因此需要仪器来快速理解和量化潜在危害。 该研究计划是由许多研究领域构建的，它以（1）开发了可快速评估辐射场和暴露的技术的开发（探测器技术，例如锌锌锌尿酸锌半导体探测器，Geiger-ruller气体气体填充柜台，硫化物刺激材料，含量型物料）研究，建模和量化对程序的重要性（气溶胶分散，计算流体动力学和蒙特卡洛建模），以及（3）探索与放射性物质使用和滥用有关的安全问题，重点是确定漏洞并更好地集成安全功能（合成环境和严重的游戏仿真）。 该计划旨在在辐射检测，测量和分析，内部和外部剂量学，辐射现场表征，紧急准备，反应和反应以及核和放射材料的安全和安全性的领域培训高素质的人员（本科，硕士，博士和博士后）。 这项研究将对健康物理和应急社区以及具有保护人员的要求的工业和政府机构具有重要意义。 这项研究将通过增加快速辐射现场表征，气溶胶行为的现象学，现场和回顾性剂量评估和安全脆弱性的知识基础，并培训许多高素质的人员，其中许多人将继续进行研究。
