What is indicated by items that display shades of brown during X-ray inspection?

Items that display shades of brown during X-ray inspection typically indicate very dense organics. In X-ray imaging, materials with different densities appear in varying shades of gray and color. Brown shades, in particular, suggest that the item has a higher density compared to other organic materials, which often show up as lighter shades. This color representation is crucial for identifying potential threats or the composition of the item being scanned.

Dense organics may include substances that are rich in carbon or have a significant mass, making them appear differently than less dense materials. This understanding is vital for personnel to recognize potential hazards or evaluate the contents without requiring physical inspection, ensuring both efficiency and safety in security screenings.
