What does a green color represent on an X-ray scanner?

The correct choice indicates that the green color on an X-ray scanner represents both inorganic and organic materials, such as cell phones and coins. X-ray scanners utilize different colors to differentiate between various types of materials based on their density and atomic composition.

In this context, organic materials typically absorb X-rays differently than inorganic materials, leading to distinct color representations on the scan. The green color is a result of a specific range of densities, allowing the scanner to efficiently identify a variety of items, including both organic items like paper and plastics and inorganic items such as metals.

Understanding how scanners categorize materials based on color coding is essential for effective security screening, as it aids in quickly identifying potential threats while ensuring that all types of items are accurately classified.
