Related to dose equivalent: Effective dose equivalent

dose equivalent (DE)

a quantity used in radiation-safety work that expresses the amount of radiation dose and the physical damage that it may produce. It is the product of the dose (in rad or gray) and a quality factor specific to the type and energy of the radiation delivering that dose. The unit of dose equivalent is the sievert (Sv) or the rem.

dose e·quiv·a·lent

(dōs ē-kwiv'ă-lĕnt)
In radiation therapy, product of absorbed dose and the quality factor; the SI unit of dose equivalent is sievert (Sv).

dose equivalent

In radiology, the product of the absorbed dose and the quality factor. Expressed in rems or sieverts, it measures the effects of absorbing different types of radiation. See: quality factor
