Committed effective dose equivalent (CEDE)

The committed effective dose equivalent or CEDE is an estimate of the radiation dose to a person resulting from inhalation or ingestion of a given amount of radioactive substance. The CEDE is expressed in rem or sieverts (Sv). It takes into account the radiation sensitivities of different organs and the time a particular substance stays in the body, which can be up to a whole lifetime.
