Which statement about x-rays and gamma rays is true?

Which statement about x-rays and gamma rays is true?

• A. Possess the same frequencies and energy
• B. Damage biologic tissue through indirect action
• C. Originate outside of the nucleus
• D. Are electromagnetic radiation

Answer: (D)

X-rays and gamma rays are both forms of electromagnetic radiation, meaning they are photons that carry energy and travel at the speed of light. This shared nature makes the statement that they are electromagnetic radiation true. They do not have the same frequencies and energies—gamma rays typically have higher energy and frequency than x-rays. Their origins differ as well: gamma rays come from nuclear transitions inside the nucleus, while x-rays arise from electron processes outside the nucleus. While ionizing radiation can damage biological tissue, the details of the damage mechanism vary and are not the defining common feature in this case.
