Committed Effective Dose Equivalent (CEDE)
The committed dose in radiation protection or radiology is a measure of the stochastic (i.e., probabilistic) health effect on an individual due to an intake of radioactive material into their body. A committed dose from an internal source is intended to carry the same effective risk as the same amount of equivalent dose applied uniformly to the whole body from an external source, or the same amount of effective dose applied to part of the body. The committed dose is not intended as a measure for acute or threshold effects of radiation exposure such as erythema, radiation sickness or death. Equivalent dose is dimensionally a quantity of energy per unit of mass, and is measured in sieverts or rems. The leading model of radiation risk predicts that an effective dose of one sievert (100 rem) carries a 5.5% chance of developing cancer. The application of this model to committed dose is disputed.

Famous quotes containing the words committed, effective, dose and/or equivalent:
“Ask anyone committed to Marxist analysis how many angels on the head of a pin, and you will be asked in return to never mind the angels, tell me who controls the production of pins.”
—Joan Didion (b. 1934)
“Basically, I have no place in organized politics. By coming to the British Parliament, I’ve allowed the people to sacrifice me at the top and let go the more effective job I should be doing at the bottom.”
—Bernadette Devlin (b. 1947)
“Whipping and abuse are like laudanum: you have to double the dose as the sensibilities decline.”
—Harriet Beecher Stowe (1811–1896)
“Every notable advance in technique or organization has to be paid for, and in most cases the debit is more or less equivalent to the credit. Except of course when it’s more than equivalent, as it has been with universal education, for example, or wireless, or these damned aeroplanes. In which case, of course, your progress is a step backwards and downwards.”
—Aldous Huxley (1894–1963)
