What does an orange color signify on an X-ray scanner?

The correct answer indicates that an orange color on an X-ray scanner primarily signifies organic materials, which commonly include substances like explosives, plastics, and paper. This encoding is based on how organic materials absorb X-ray radiation differently than inorganic materials. Organic substances tend to have lower atomic numbers and therefore appear with distinctive colors on the scanner’s display, helping operators identify potentially hazardous items or contraband.

In the context of security screening, being able to differentiate between what is organic and inorganic is crucial. Organic materials often present potential risks in airports, courthouses, and secure facilities, making this color coding an important tool for security personnel. The specifics of this classification are essential in training and operational contexts to prepare court officers and security staff to recognize threats effectively.
