For most fluoroscopy examinations … WebOn the other hand, in the deterministic effects the damages caused by the radiation increase with the increase in the dose. In this specific effect there is a threshold dose. …

WebDeterministic (Non-Stochastic) Effects General Early (acute) effects are non-stochastic because they are pimarily brought about by cell death. 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. WebDeterministic effects (or non-stochastic health effects) are health effects that are related directly to the absorbed radiation dose, and the severity of the effect increases as the dose increases. Deterministic effects have a threshold below which no detectable clinical effects do occur. The threshold may be very low (of the order of magnitude ...
