Deterministic effects differ from stochastic effects in that they:

• A. occur with no dose threshold
• B. have a dose threshold and increase in severity with dose
• C. only occur with acute exposure
• D. do not depend on dose

Answer: (B)

Deterministic effects show a clear dose-response behavior: there is a threshold dose below which no effect is observed, and once that threshold is surpassed, tissue damage occurs and the severity of the effect increases as the dose goes up. That’s why this description fits deterministic effects—the presence of a dose threshold and the rising severity with higher dose. In practical terms, you’ll see effects like skin reddening or radiation sickness only after exceeding a certain exposure, and worse outcomes with larger doses. By contrast, stochastic effects (like cancer) are driven by probability that increases with dose, but there isn’t a simple dose threshold where the effect suddenly appears, and the severity isn’t tied to the dose in the same direct way. So the statement that best captures how deterministic effects differ is that they have a dose threshold and increasing severity with dose.
