Strategy to Improve Scintillation Detector Capabilities to Enhance Nuclear Safety and Security

该研究计划包括提高闪烁探测器能力的策略，以加强核安全和保障。它于2010年在安大略理工大学发起，旨在研究新型辐射传感器的基本特性，并开发用于在线辐射光谱和剂量测定的新算法。该计划的基本原理是：1)填补新技术对下一代辐射检测仪器的需求；2)实施该技术以加强国家安全，核不扩散和核工业的职业安全；3)培养和参与健康物理，辐射和核科学领域的辐射科学和核工程专业学生。加上我在UOIT的辐射和核技术相关的教学活动，在未来五年，我计划：1)继续研究新型辐射传感器的特性和特性，并考虑在加拿大生产的可能性；2)研究采用不同材料生产高灵敏度传感器的可能性，以同时检测不同类型的辐射；3)开发剂量计算和光谱分析的经验算法；4)与工业界合作，为工业实施提供所需的核数据。

This research program consists of a strategy to improve scintillation detector capabilities to enhance nuclear safety and security. It was initiated in 2010 at the University Of Ontario Institute Of Technology to investigate the fundamental proprieties of novel radiation sensors and develop new algorithms for online radiation spectrometry and dosimetry. The rationale for this program is: 1) to fill the need of new technologies for the next generation of radiation detection instrumentation 2) to implement this technology to enhance the national security, non proliferation and occupational safety in nuclear industry 3) to train and engage radiation science and nuclear engineering students in the field of health physics, radiation and nuclear sciences. Adding to my teaching activities related to radiation and nuclear technologies at UOIT, over the next five years, I plan to: 1) to continue investigating the characteristics and proprieties of new radiation sensors with the possibility of growing them in Canada 2) investigate the possibility to incorporate different materials to produce highly sensitive sensors for simultaneous detection of different types of radiation 3) develop empirical algorithms for dose calculation and spectrum analysis and 4) collaborate with industry and provide the needed nuclear data for industrial implementation. Approach: The scientific approach consists of: 1) Modeling the optical properties of scintillators 2) conducting experimental studies and benchmark the models using the recently established applied radiation lab at UOIT and 3) develop empirical algorithms to calculate dosimetric and spectrometric quantities to compensate for the physical property limitations of the sensors. Novelty: This research program has a primary novelty associated with the implementation of new approach to develop accurate, efficient and rapid radiation detection systems. The second novelty is that these sensors are flexible for implementation in small devices as well as in large integrated systems and finally they can simultaneously detect different type of radiation.
