What shows up orange on airport xray?

Current airport X-ray scanners produce images in orange, blue and green. Each color corresponds to a material category—orange means organic material (food, paper, marijuana), green is for medium-dense non-organic materials like plastic soda bottles, and blue means metals or hard plastics.



On airport X-ray scanners, the color orange is used to identify organic substances. This category includes a vast range of everyday items such as food, clothing, paper, books, and plastics. Because organic materials are composed of lower-density elements like carbon, hydrogen, and oxygen, the scanner's software color-codes them as orange to distinguish them from inorganic materials like metals (which show up as blue) or "mixed" materials like glass and some dense plastics (which show up as green). However, security officers pay close attention to orange shapes because explosives—which are often nitrogen-based organic compounds—also appear in shades of orange. This is why things like large blocks of cheese, thick bundles of paper, or jars of peanut butter may trigger a manual bag search, as their density and orange color profile can mimic the appearance of certain hazardous materials on the operator's screen.

Airport body scanners alert the TSO to threats—mainly weapons such as knives, guns and explosives. They are designed to detect “metallic and nonmetallic threat items,” according to the TSA. Those are things like explosives or knives made out of materials other than metal, like ceramics, says Malvini Redden.

Body scanners are looking for items that could be potential threats; they're not looking at your physical body. The TSOs see “a generic human form—or avatar—to ensure passenger privacy while maintaining security effectiveness,” Langston says. This looks kind of like a gingerbread man or paper doll.

The technology uses harmless radio waves to penetrate non-metallic items such as fabric, leather, and plastic, revealing 3D images of the objects within. Millimeter wave scanners are extremely sensitive and can easily detect traces of drug particles that might otherwise go unnoticed.

The technology that is used in airport security scanners has the potential to be a skin cancer diagnostic tool, a scientist is claiming. The scanners use so-called terahertz radiation (t-rays), which has the ability to look through human skin and tissue. T-rays are considered non-ionizing, similar to visible light.
