Radiation Effects: Time-Dose (ICRP60 – 1991)

• Deterministic: threshold for effect → below, no effect; above, certainty, and severity increases with dose. Acute and late effects, clinically attributable in the exposed individual.

• Stochastic: probability of effect related to dose, down to zero (?) dose. Expressed after a latency period, epidemiologically attributable in large populations.
