What items are subject to search upon entering the Protected Area?

The correct choice identifies that both vehicles and individuals with their belongings are subject to search upon entering the Protected Area. This policy is in place to maintain security and ensure that no unauthorized items enter sensitive areas. Security measures in nuclear facilities are exceptionally stringent due to the nature of the materials and operations involved.

Searching vehicles allows security personnel to check for any unauthorized tools, materials, or potential threats that could compromise safety. Likewise, searching individuals and their belongings—such as bags or packages—ensures that no prohibited items are brought into the facility, which could include anything from personal electronics to unauthorized access tools. This comprehensive approach helps to safeguard both the physical security of the site and its operational integrity.

The other choices are limited in their scope, as they either restrict the search to just one category—vehicles, or hand-carried items—or only focus on individuals without accounting for the possible threats that may be hidden within vehicles. Thus, recognizing the importance of searching both vehicles and individuals ensures a more robust security protocol.
