A unit of biologically equivalent dose, defined as the absorbed dose in rad multiplied by the quality factor (Q).
This is the measure that indicates the degree of biological damage caused by radiation. Dose equivalent is measured in rems.
A term used to express the amount of effective radiation received by an individual. A dose equivalent considers the type of radiation, the amount of body exposed, and the risk of exposure. Measured in rems. (See rem).
absorbed dose in a tissue or organ, multiplied by a weighting factor that takes into account the biological effect related to the type and energy level of the radiation in question. Expressed in sieverts (Sv)
a quantity used in radiation protection to place all radiation on a common scale for calculating tissue damage. Dose equivalent is the absorbed dose in grays times the quality factor. The quality factor accounts for differences in radiation effects caused by different types of ionizing radiation. Some radiation, including alpha particles, causes a greater amount of damage per unit of absorbed dose than other radiation. The sievert (Sv) is the unit used to measure dose equivalent. For more information, see " Primer on Radiation Measurement" at the end of this document.
The common unit for DE is the Roentgen Equivalent Man (REM). DE = 1 REM = RAD x Q
The product of absorbed dose and several modifying factors (e.g., the quality factor) which permits summing the radiations of different kind as a measure of the expected biological effect.
The product of absorbed dose and Quality Factor (or Radiation Weighting Factor) and all other modifying factors necessary to quantify the effects of radiation to persons. Dose equivalent is used for radiation protection purposes, engineering design criteria and for legal and administrative purposes. In day to day life, it is often simply called "Dose". The old unit for dose equivalent is the rem while the SI unit is the sievert (Sv). 1 Sv = 100 rem
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 the sievert (Sv). The ICRP defines this as the equivalent dose, which is sometimes used in other countries.
A quantity used in radiation protection. It expresses all radiations on a common scale for calculating the dose for purposes of radiation safety. It is the product of the absorbed dose in rad or gray and a quality factor, whose value depends on the radiation. (The unit of dose equivalent is the rem. In SI units, the dose equivalent is the sievert, which equals 100 rem.)
The product of absorbed dose (D) in rad (or gray) in tissue, a quality factor (Q), and other modifying factors (N). Dose equivalent is expressed in units of rem (or sievert) (1 rem = 0.01 sievert).
This is the amount of biological damage to human tissue caused by radiation. The absorbed radiation dose to human tissue times the quality factor. The units of the dose equivalent are the rem or sievert.
A dose normally applied to biological effects and including scaling factors to account for the more severe effects of certain kinds of radiation.
the product of the dose times a number (quality factor) which takes into account the biological effect of each radiation
A quantity used for radiation protection purposes that expresses on a common scale for all radiations, the irradiation incurred by exposed persons. It is defined as the product of the absorbed dose, the quality factor, and any other modifying factors. The rem and the sievert (SI) are units of 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). 1 Sv = 100 rem.
Radiation dose derived from absorbed dose in tissue, but modified to take into account differing biological effectiveness of various types of radiation. The units of dose equivalent are the rem and sievert. (1 sievert = 100 rem)
The product of the absorbed dose from ionizing radiation and such factors as account for biological differences due to the type of radiation and its distribution in the body in the body.
