Which of the following describes absorption in the context of X-ray interaction with tissue?

• A. Photons create new radiation through scattering
• B. All X-ray energy is transmitted through the tissue
• C. Some or all X-ray energy is absorbed by the tissue
• D. Radiation passes through tissue without interaction

Answer: (C)

In the context of X-ray interaction with tissue, absorption refers to the process by which X-ray photons transfer their energy to the atoms in the tissue, resulting in either energy being absorbed or causing the tissue atoms to become ionized. When X-ray photons encounter tissue, some of them will interact with the atoms and be absorbed, meaning that their energy is taken up by the tissue rather than being transmitted or scattered. This absorption is significant because it is responsible for producing the contrast seen in X-ray images; areas where more energy is absorbed will appear differently than areas where less energy is absorbed. Therefore, the correct description captures the essential process of how X-rays can interact with tissue, leading to a variety of biological effects and imaging results. In contrast, the other choices describe processes that do not accurately capture the concept of absorption. For instance, the notion that all X-ray energy is transmitted through the tissue suggests that none of the energy is absorbed, which does not reflect the reality of how X-rays interact with biological materials. Similarly, the idea that photons create new radiation through scattering involves a different interaction entirely and does not pertain to absorption. Lastly, stating that radiation passes through tissue without interaction implies a lack of any energy transfer, which ignores the
