Which term describes health effects that vary in severity with dose and have a believed threshold?

Deterministic effects are health effects that have a known threshold and their severity increases with the dose of radiation exposure. This means that below a certain dose, these effects are unlikely to occur, but once the dose surpasses that threshold, the risk of experiencing such effects rises significantly. Examples of deterministic effects include skin burns, radiation sickness, and organ damage, all of which have clearly defined relationships between dose and effect severity.

In contrast, stochastic effects are characterized by a probability of occurrence that increases with dose, but there is no threshold dose below which the risk is absent. Genetic effects refer specifically to changes in DNA that can be passed on to future generations, regardless of dose. Acute effects generally refer to immediate reactions to high levels of radiation exposure. However, the defining factor of deterministic effects is their dose-dependent relationship and the existence of a threshold, making them the correct term in this context.
