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:
“What man who carries a heavenly soul in him, has not groaned to perceive, that unless he committed a sort of suicide as to the practical things of this world, he never can hope to regulate his earthly conduct by that same heavenly soul?”
—Herman Melville (1819–1891)
“Society’s double behavioral standard for women and for men is, in fact, a more effective deterrent than economic discrimination because it is more insidious, less tangible. Economic disadvantages involve ascertainable amounts, but the very nature of societal value judgments makes them harder to define, their effects harder to relate.”
—Anne Tucker (b. 1945)
“When a mother quarrels with a daughter, she has a double dose of unhappiness—hers from the conflict, and empathy with her daughter’s from the conflict with her. Throughout her life a mother retains this special need to maintain a good relationship with her daughter.”
—Terri Apter (20th century)
“For some men the power to destroy life becomes the equivalent to the female power to create life.”
—Myriam Miedzian, U.S. author. Boys Will Be Boys, ch. 4 (1991)
