A radiation effect that is associated with a specific dose threshold is called a?

A radiation effect that is associated with a specific dose threshold is referred to as a tissue reaction. This type of effect is characterized by a clear relationship between the amount of radiation exposure and the severity of the effect; as the dose increases beyond the threshold, the likelihood and severity of the response in the tissue also increase. For instance, conditions such as skin burns or radiation-induced cataracts typically don’t occur below a certain exposure level, known as the threshold dose.

Deterministic effects, often tied to tissue reactions, also imply that these effects have a dose-dependent relationship, but the term itself is broader and could include other definitions outside of the threshold context. Stochastic effects, on the other hand, do not have a threshold and are randomly occurring effects that have a probability of happening rather than severity based on dose. Acute radiation syndrome refers specifically to the symptoms arising from high doses of radiation over a short period, which also relates to deterministic effects but is a specific condition rather than a general term for threshold-associated effects.
