Dose equivalent definition

Dose equivalent. (HT) means the product of the absorbed dose in tissue, quality factor, and all other necessary modifying factors at the location of interest. The units of dose equivalent are the sievert (Sv) and rem.

Dose equivalent means the product of the absorbed dose from ionizing radiation and such factors as account for differences in biological effectiveness due to the type of radiation and its distribution in the body as specified by the International Commission on Radiological Units and Measurements (ICRU).

Dose equivalent means the product of absorbed dose and appropriate fac- tors to account for differences in bio- logical effectiveness due to the quality of radiation and its spatial distribution in the body. The unit of dose equiva- lent is the ‘‘rem.’’ (One millirem (mrem)= 0.001 rem.)

Examples of Dose equivalent in a sentence

• Specific federal regulation information can be found on: § 20.1208 Dose equivalent to an embryo/fetus.

• Dose equivalent is calculated by multiplying absorbed dose (rad, Gy) by a quality factor (QF) that accounts for the effectiveness of the radiation, relative to gamma or X-rays, in causing a biological effect, i.e., rem = rad x QF; Sv = Gy x QF.

• Dose equivalent determinations for internally deposited radioactive materials also take into account other factors such as the non-uniform distribution of some radionuclides (e.g. I- 125 in the thyroid).

• Dose equivalent is the absorbed dose at a certain point in the tissue, this absorbed dose is then weighted by a distribution of a quality factors (Q).

• Dose equivalent (HT)--The product of the absorbed dose in tissue, quality factor, and all other necessary modifying factors at the location of interest.

More Definitions of Dose equivalent

Dose equivalent means the product of the absorbed dose for ionizing radiation and such factors as account for differ- ences in biological effectiveness due to the type of radiation and its distribution in the body as specified by the international com- mission on radiological units and measurements (ICRUM).

Dose equivalent means the absorbed radiation dose to a human being, modified by appropriate radiation weighting factors, depending on the type of ionizing radiation source, or tissue/organ weighting factors (as may be necessary).

Dose equivalent. (HT) means the product of the absorbed dose in tissue, quality factor, and all other necessary modifying factors at the location of interest. The units of dose equivalent are the rem and sievert (Sv). Other necessary modifying factors include the specific energy or spectrum of energies of radiation; the specific size and shape of the source of radiation and radiation detector; the specific radiation scattering characteristics in the environment; differences in temperature, humidity and atmospheric pressure of the radiation detector and radiation environment; limitations of the radiation detector; characteristics of the specific tissues absorbing the radiation; and differences in physiological responses in specific persons absorbing the radiation.

Dose equivalent. (H ), means the product of the absorbed

Dose equivalent means the absorbed dose in rads times certain modifying factors and is a quantity that expresses on a common scale for all radiation a measure of the postulated effect on a given organ from small amounts of radiation. The special unit of dose equivalent is the rem.

Dose equivalent means the absorbed dose from ionizing radiation expressed in terms of Rads multiplied by such a factor as account for differences in biological effectiveness due to the type of radiation and its distribution in the body as specified by the International Commission on Radiological Units and Measurements (ICRU).

Dose equivalent. (HT) means the product of the absorbed dose in tissue, quality factor,
