Deterministic effects follow a threshold dose
WebMar 21, 2024 · Models. Cancer induction as a result of exposure to radiation is thought by most to occur in a stochastic manner: there is no threshold point and the risk increases in proportionally with dose. Although the exact model which predicts the stochastic effects of radiation is contentious, numerous models do exist including: adaptive-dose response ... WebDeterministic effects are those responses which increase in severity with increased dose if the dose increases the severity of an effect increases. All early effect and most tissue …
