WebThe deleterious effect ionizing radiation has on human tissue can be divided into two types: non-stochastic (deterministic) or stochastic effects. Deterministic (Non-Stochastic) Effects Deterministic effects only occur once a threshold of exposure has been exceeded. The severity of deterministic effects increases as the dose of exposure increases. WebOct 10, 2024 · The effects of radiation are down to how much and where the energy is deposited. A large weighting factor (WR) leads to highly localised damage whereas gamma/x-rays deposit energy/dose over a much greater range.

Late (delayed effects) can be deterministic or stochastic. Deterministic late effects involve the death of slowly dividing 24 yg cells, e.g. those in the liver.

WebAbstract. Deterministic effects are distinguished from stochastic effects for radiation protection purposes by the following characteristics: both incidence and severity increase as a function of dose after a threshold dose is reached. Cell killing is central to all deterministic effects with the exception of radiation-induced cataracts. WebJun 14, 2024 · 1.

WebApr 11, 2024 · The harmful effects of ionising radiation can be divided into stochastic and deterministic, or early and late, according to another division. Stochastic radiation causes effects where the likelihood (but not severity) is directly proportional to the dose. This include malignant tumours and damage to the genetic material.
