Effects of radiation where the probability of occurrence, not severity, is proportional to the dose are called:

• A. Deterministic effects
• B. Genetic effects
• C. Somatic effects
• D. Stochastic effects

Answer: (D)

Stochastic effects are the kind where the chance of the effect occurring increases with the radiation dose, but the severity of the effect does not depend on how large the dose was. This means the probability of cancer or a heritable genetic change rises with greater exposure, while if the effect does occur, its seriousness isn’t tied to the exact amount of dose. In contrast, deterministic effects have a threshold below which they don’t occur, and their severity grows with dose (like skin reddening or cataracts in high exposures). Genetic effects are typically viewed as stochastic because they concern the probability of occurrence in future generations rather than a dose-dependent increase in severity for the irradiated individual. So the concept described is stochastic effects.
