This paper presents a high-level overview of the threats that high-risk radioactive sources represent, and their potential use as radiological weapons. The objective is to provide a discussion on existing threat assessment methodologies and security practices to protect high-risk radioactive sources, including physical protection systems and security management. I explore the particular challenges associated with protecting high-risk radioactive sources against potential insider threats, and some of the gaps related to transportation of such sources. Following the theory of Situational Crime Prevention, I propose different security approaches for mitigating the risk, and explore different options and offer recommendations. The Canadian Nuclear Safety Commission (CNSC) plays an important role ensuring that Safety and Security are harmonized. In 2013, CNSC published regulatory document REGDOC2.12.3 to enhance the security of radioactive sealed sources in Canada. In doing so, CNSC's role in securing radioactive sources made sure that safety and security can work together without impeding one another. Radioactive sources are used worldwide and provide many benefits to the population. In this perspective, the Canadian approach emphasizes the importance of safety and security interfaces, not forgetting the fact of the benefits arising from the use of sealed sources.
