研究项目涉及辐射探测技术、剂量学、现场表征和安全五感，需要仪器快速了解和量化潜在危害。该研究计划由多个研究领域组成，包括：(1)开发用于快速评估辐射场和暴露的现场便携式仪器和技术（探测器技术，如碲化镉锌半导体探测器、盖革-穆勒气体填充计数器、硫化锌闪烁探测器、光激发发光材料和电子顺磁共振材料）；(2)实验研究；建模和量化对程序有重要意义的辐射场（气溶胶扩散、计算流体动力学和蒙特卡罗建模），以及(3)探索与放射性物质使用和误用相关的安全问题，重点是确定漏洞并更好地与安全功能集成（合成环境和严肃游戏模拟）。主要培养辐射检测、测量与分析、内外剂量学、辐射场表征、应急准备、响应与对策、核与放射性材料安全与安保等领域的高素质人才（本科、硕士、博士、博士后）。该研究对卫生物理界和应急响应界，以及对人员保护有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场表征、气溶胶行为现象学、现场和回顾性剂量评估和安全漏洞的知识库，以及通过培训一批高素质人员（其中许多人将继续从事研究），使科学界受益。

The research program is in radiation detection techniques, dosimetry, field characterization and safety 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.
