What technology is commonly used in baggage screening?

X-ray machines are a cornerstone of baggage screening technology in aviation security. They work by emitting X-rays that penetrate the items within a bag, creating images based on the density and material composition of the objects present. Security personnel analyze these X-ray images to identify any suspicious items or potential threats, such as explosives, weapons, or prohibited items. This method is effective because it allows for a non-intrusive examination of baggage, enabling a fast and efficient screening process essential for airport security.

While other technologies like infrared cameras, magnetic resonance imaging, and thermal scanners have their applications in various fields, they are not predominantly used for standard baggage screening in airports. Infrared cameras might be utilized for detecting temperature anomalies, magnetic resonance imaging is more relevant in medical settings, and thermal scanners can assess heat signatures but do not provide the detailed structural imaging required for effective baggage inspection. Thus, X-ray machines remain the primary technology for this purpose, ensuring that security checks are both thorough and efficient.
