• Some effects of radiation on human health are stochastic meaning

that their probability of occurrence increases with dose, while the

severity is independent of dose.

• Examples:-Radiation-induced cancer, tetrogenesis, cognitive

decline, and heart disease.

• Other conditions such as radiation burns, acute radiation

syndrome, chronic radiation syndrome, and radiation-induced

thyroiditis are deterministic, meaning they reliably occur above a

threshold dose, and their severity increases with dose.
