What type of materials are identified by the orange X-ray color?

1. Metals and hard plastics

2. Biological materials and organic compounds

3. Dense plastic alloys

4. Fabric and paper products

The correct answer is: Biological materials and organic compounds

The correct identification of materials associated with the orange color in X-ray imaging refers to biological materials and organic compounds. This color coding serves as a visual cue for security personnel to quickly recognize potentially organic threats, such as food, liquids, or biological samples, which are vital in screening procedures. Understanding this context helps in identifying materials that can pose risks, ensuring that security measures are both effective and efficient. The other types of materials, like metals, dense plastic alloys, or fabric and paper products, are typically represented by different color codes, indicating their distinct densities or compositions which are important in evaluating potential risks during screening.
