Which of the following colors on the X-ray scanner is used to identify lead or heavy metals?

The color designated for identifying lead or heavy metals on X-ray scanners is typically black or dark blue. This coding is crucial because it helps operators quickly and efficiently recognize materials that could signify security risks or require special handling.

Lead and heavy metals have a high atomic number, which results in a distinct and recognizable signature on X-ray scans. The use of black or dark blue in the scanner’s display enhances visibility and ensures that personnel can swiftly act upon identifying these materials. Familiarity with the color codes for various materials is essential in ensuring safety and compliance in environments where X-ray scanners are utilized, such as in security checks at airports or courthouses.

Thus, recognizing that black or dark blue is associated with heavy metals aligns with the safety protocols established for operating X-ray scanning equipment. Understanding this coding system aids in effective screening and helps prevent potential threats from being overlooked.
