Exposure to radiation can cause two kinds of health effects. Deterministic effects are observable health effects that occur soon after receipt of large doses.

The radiation dose determines the severity of a deterministic effect and the probability of a stochastic effect.
How long does a radionuclide stay in the body?
When a person inhales or ingests a radionuclide, that radionuclide is distributed to different organs and stays there for days, months, or years until it decays or is excreted. The radionuclide will deliver a radiation dose over a period of time. The dose that a person receives from the time the nuclide enters the body until it is gone is the committed dose. FGR-11 calculates doses over a 50-year period and presents the committed dose equivalent for each organ plus the committed effective dose equivalent
