Which type of screening equipment is effective for checking items brought into facilities?

Conveyor belt style x-ray machines are particularly effective for screening items brought into facilities because they provide a comprehensive view of the contents of bags and packages. This type of technology allows security personnel to visualize the items inside a container without needing to open it, which ensures a quick and efficient screening process. The images produced by these machines can highlight anomalies, identify potential threats, and differentiate between benign items and dangerous materials.

In contrast, magnetometers are more suited for detecting metal objects and do not offer a detailed view of the contents carried by individuals. Hand-held scanners, while useful for focused searches on specific areas, lack the ability to screen multiple items quickly and comprehensively like an x-ray machine can. Biometric scanners measure physical attributes like fingerprints or facial patterns and are used primarily for identifying individuals rather than inspecting carried items. Thus, the conveyor belt style x-ray machines stand out for their capability to scan and analyze various types of items efficiently as people enter a facility.
