What is one of the enhanced security methods for nuclear gauges?

One of the enhanced security methods for nuclear gauges is facility security. This involves implementing robust physical and operational security measures to protect nuclear gauges from theft, unauthorized access, and other threats. Facility security can include controlled access to the areas where gauges are stored or used, surveillance systems to monitor for intrusions or suspicious activities, and staff training on security protocols. By ensuring that only authorized personnel can access these sensitive instruments, the risk of misuse or accidents is significantly reduced, enhancing overall safety and security.

In contrast, other options like increasing transportation speed might compromise safety by not allowing adequate security checks, while reducing personnel limitations could lead to insufficient oversight of security practices. Limiting public access is important but often falls under broader facility security measures, as secure facilities inherently restrict access to authorized individuals.
