Deterministic effects are best described as which of the following?

• A. Unpredictable
• B. Random
• C. Probabilistic
• D. Predictable

Answer: (D)

Deterministic effects are effects whose occurrence and severity are predictable once the radiation dose is known. They have a threshold, meaning they don’t occur below a certain dose, and above that threshold their severity increases with higher doses. This makes it clear when they will happen and how bad they will be for a given exposure. Examples include skin erythema, epilation, and cataracts—each appears only after crossing a specific dose level and becomes more severe as the dose rises. In contrast, stochastic effects are probabilistic, with their likelihood increasing with dose but not tied to a threshold for appearance, and their severity is not dose-dependent.
