WebDec 14, 2024 · Deterministic and Stochastic Effects. In radiobiology, most adverse health effects of radiation exposure are usually divided into two broad classes: Deterministic effects are threshold health effects, that are related directly to the absorbed radiation dose and the severity of the effect increases as the dose increases. WebHealth effects from radiation doses can be grouped into two categories: deterministic and stochastic. Deterministic effects occur after a threshold dose is reached, meaning at dose below the threshold are not expected …
