Which color typically indicates biological materials in X-Ray images?

1. Blue

2. Red

3. Orange

4. Green

The correct answer is: Orange

In X-ray imaging, biological materials are typically represented by the color orange. This color coding helps security and medical personnel quickly identify organic materials, which include tissues and body fluids. The use of color in X-ray imaging enhances the clarity of the images by distinguishing between different types of materials. Recognizing biological materials is crucial in contexts like airport security scanning, where identifying organic substances can be vital for safety and compliance. Other colors may correspond to different materials or substances, making it important to understand this color convention in the context of X-ray interpretation.
