Design of Space Radiation Material

加拿大核实验室（CNL）是加拿大首屈一指的核科学和技术（S&T）组织 **，位于安大略的乔克河。CNL的使命是促进高素质人才的发展，并 ** 成为业务创新和技术的推动者。联邦政府是 **CNL客户的代表，并支持与健康、安全和安保、** 和环境有关的主题领域的众多项目。在CNL的放射生物学和健康分支内，目前正在进行的联邦资助 ** 研究项目之一题为“空间辐射剂量测定、屏蔽和中子计量学”。该项目于2016/17财年开始，预计将持续到2018/19财年。该项目的 ** 目标是宣传和改进加拿大的辐射防护准则，以应对：（1）在空间遇到的复杂 ** 高能辐射环境，和（2）在核电厂等地面 ** 环境中遇到的中子场。第一个目标目前的重点是建议和制定 ** 月球和火星飞行任务的辐射剂量限值。加拿大航天局（加空局）代表CNL ** 的联邦政府利益攸关方参与这项工作。瑞尔森大学 ** 与CNL联合开展的拟议活动将有助于了解与空间辐射有关的最新知识。

Canadian Nuclear Laboratories (CNL) is Canada's premier nuclear science and technology (S&T) organization**located in Chalk River, Ontario. CNL's mission is to foster the development of highly qualified people and to**become an enabler of business innovation and technology. The Federal Government is represented among**CNL's customers and supports a multitude of projects across theme areas related to health, safety and security,**and the environment. Within the Radiobiology and Health Branch at CNL, one of the federally funded**research projects currently underway is titled "Space Radiation Dosimetry, Shielding, and Neutron Metrology".**The project commenced in fiscal year 2016/17 and is anticipated to continue to fiscal year 2018/19. The**objectives of the project are to inform and improve Canadian radiation protection guidelines for (1) complex,**high energy radiation environments as encountered in space, and (2) neutron fields encountered in terrestrial**settings such as nuclear power plants. The first objective is currently focused on recommending and developing**radiation dose limits for missions to the Moon and Mars. The Canadian Space Agency (CSA) represents CNL's**Federal Government stakeholder for this effort. The proposed activity to be conducted jointly between Ryerson**University and CNL will shed the light on the latest knowledge related to space radiation.
