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

Thus, when biologic measures of internal OP pesticide dose are available, cumulative OP pesticide dose equivalents can be calculated for a population by converting individual OP pesticide doses to index chemical toxicity equivalent doses, using RPFs, and then summing them.
