What are nonstochastic (deterministic) radiation effects?

Nonstochastic (deterministic) radiation effects are tissue reactions that only occur after a certain dose threshold is reached, and once that threshold is exceeded, the severity of the effect increases as the dose increases. A classic example is skin erythema: there is a dose below which no erythema occurs, and beyond the threshold the reaction becomes more severe with higher doses. In contrast, effects described as having no threshold but increasing probability with dose are stochastic effects, such as cancer or inherited genetic changes, where the chance of occurrence rises with dose but the severity is not dose-dependent.
