What measures can prevent unauthorized access to radioactive materials?

Preventing unauthorized access to radioactive materials is crucial for ensuring safety and compliance with regulations. The choice that encompasses comprehensive security measures includes physical barriers, access control systems, and surveillance.

Physical barriers, such as locked storage cabinets or rooms, physically restrict unauthorized individuals from reaching radioactive materials. Access control systems, which may involve key cards or biometric scanners, help monitor and limit who can enter restricted areas. Surveillance, through security cameras or monitoring services, adds an additional layer of security by allowing for real-time observation of these areas, enabling prompt response to any suspicious activity.

While having a single key holder can simplify access management, it poses a significant risk if that individual is unable to perform their duties or if the key falls into the wrong hands. Periodic staff training is important, but it alone cannot prevent unauthorized access without physical measures in place. Similarly, informing workers about radioactive materials is essential for awareness and safety procedures but does not inherently prevent unauthorized access. Thus, the most effective approach combines all necessary security elements to protect against potential breaches.
