Dose fractionation can affect tissue repair and risk by:

Dose fractionation can affect tissue repair and risk by:

• A. It increases the likelihood of all radiation-induced effects.
• B. Spreading total dose over multiple sessions allows repair between exposures, potentially reducing deterministic effects and some stochastic risk.
• C. It has no impact on risk.
• D. It only reduces deterministic effects, not stochastic.

Answer: (B)
