Ensuring security when using radioactive materials in a radiological facility

The number of radioactive materials used in radiological facilities around the world requires an effective security system to protect both facility and environment. In these facilities, a Physical Protection System (PPS) is routinely devised implemented from potential adversaries. A physical protection created for hypothetical site thus evaluated against harmful actions posed by possible attacker this study. An Adversary Sequence Diagram (ASD) oncology center study, effectiveness protective systems through use estimate adversary sequence interruption (EASI) model action on facility. Risk assessment was done performing iterations probability attacks obtain risk values using python program. performed depicted reduction chances after application improvement strategies. identifying interrupting adversary's toward increased significantly indicating that PPS provides improved reliable system. purpose work articulate requirements handling at
