The effect of low doses of X-rays on adult tissues and organs is considered to be similar to

• A. Rapid healing
• B. Premature aging
• C. Increased immunity
• D. No effect

Answer: (B)

Low doses of ionizing X-ray photons can cause occasional DNA damage in adult tissues. The body’s repair systems fix most of this damage, but some lesions can persist or accumulate with repeated exposure. Over time, this cumulative effect can lead to cellular aging processes and tissue wear, which is described as premature aging. That’s why this option fits best. The other ideas don’t align with how low-dose radiation behaves: rapid healing would imply a transient, advantageous response, which isn’t how radiation damage works; increased immunity is not a typical outcome of low-dose exposure; and claiming no effect ignores the potential for cumulative damage even at small doses.
