Which color represents less dense plastics and alloys in X-ray imaging?

1. Blue/Black

2. Green

3. Orange

4. Red

The correct answer is: Green

The color that represents less dense plastics and alloys in X-ray imaging is green. In this context, color coding in imaging techniques is often utilized to help technicians and radiologists quickly identify the materials being observed. Less dense materials such as certain plastics and alloys typically appear in green because this color indicates a lower atomic number or density, which corresponds to the reduced attenuation of X-rays. Each color used in this imaging technique serves a specific purpose and follows a standardized guideline, making it easier for professionals to analyze the results swiftly and accurately. By using green for less dense materials, practitioners can effectively differentiate between various substances within the imaged area. This understanding is crucial for accurate diagnosis and assessment in various fields, including medical imaging and materials analysis.
