What electronic security measures are utilized to protect nuclear facilities?

The correct choice highlights a comprehensive approach to electronic security specifically designed to protect nuclear facilities. Surveillance systems, access control systems, and intrusion detection systems work together to enhance the overall security framework.

Surveillance systems are crucial in monitoring activities around and within nuclear facilities, allowing security personnel to observe for any unauthorized access or suspicious behavior in real-time. Access control systems manage who can enter sensitive areas, employing technologies like key cards, biometric scanners, or PIN codes to ensure that only authorized personnel can gain entry. Intrusion detection systems play a vital role in alerting security assets to breaches or attempts to bypass security measures, using sensors or alarms to indicate when someone crosses a secured perimeter.

This integrated set of electronic measures provides layered security, enhancing both the detection and deterrence of potential threats. Each component complements the others, creating a more robust protective environment that basic locks, periodic checks, or limited surveillance could not achieve on their own. The synergy among these technologies is critical to maintaining the safety and security of nuclear materials and facilities.
