Which X-ray color identifies non-plastic explosives?

1. Red

2. Green

3. Blue/Black

4. Orange

The correct answer is: Orange

The correct answer is associated with the specific X-ray color that reliably identifies non-plastic explosives. In the context of X-ray imaging used in security and airport screenings, each color represents different materials based on their atomic density and composition. Non-plastic explosives typically have a distinct chemical composition that results in them being represented in a specific color on X-ray scans. That color, in this case, is orange. This identification is crucial for security personnel to recognize potential threats quickly, as non-plastic explosives are often used in various forms of illicit activities. In contrast, other colors correspond to different materials or types of explosives. For instance, red may indicate organic materials or certain types of plastics, while green might represent metals or other inorganic substances, and blue or black could suggest various types of accessories or items that do not present a significant threat. The ability to differentiate these colors allows for efficient and effective security procedures.
