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

该研究计划包括一项提高闪烁探测器能力以加强核安全和安保的战略。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测定和剂量测定的新算法。该计划的基本原理是：1）满足下一代辐射探测仪器新技术的需求2）实施该技术以加强核工业的国家安全，不扩散和职业安全3）培养和吸引辐射科学和核工程专业的学生在健康物理，辐射和核科学领域。除了我在UOIT与辐射和核技术相关的教学活动外，在未来五年内，我计划：1）继续研究新辐射传感器的特性和性能，并有可能在加拿大种植这些传感器; 2）研究采用不同材料生产高灵敏度传感器的可能性，以便同时检测不同类型的辐射; 3）开发用于剂量计算和谱分析的经验算法，以及4）与工业界合作，并为工业实施提供所需的核数据。 方法：科学方法包括：1）对闪烁体的光学特性进行建模2）使用最近在UOIT建立的应用辐射实验室进行实验研究并对模型进行基准测试3）开发经验算法来计算剂量和光谱量，以补偿物理特性传感器的限制。 新奇：该研究计划具有与开发准确，高效和快速辐射检测系统的新方法的实施相关的主要新奇。第二个新奇在于，这些传感器对于在小型设备以及大型集成系统中的实施是灵活的，并且最终它们可以同时检测不同类型的辐射。

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.
