What is a common application of both gamma rays and X-rays?

• A. To measure temperature
• B. To see inside the body
• C. To create electricity
• D. To produce music

Answer: (B)

Gamma rays and X-rays are both forms of high-energy electromagnetic radiation that have the ability to penetrate human tissue, making them invaluable in medical imaging. The use of X-rays, for instance, allows doctors to create images of the structures within the body, including bones and soft tissues, which aids in diagnosing various medical conditions. Similarly, gamma rays are utilized in certain medical imaging techniques, such as PET scans, which help visualize metabolic activity and can detect abnormalities in tissue function. Both of these types of radiation are fundamental in medical applications for visualizing internal bodily structures and conditions, which is why the correct answer pertains to seeing inside the body.
