Radiation: Quality Factor radiation weighting factor WR instead of the dose equivalent con- cept with the quality factor Q(L) has many consequences. The value of WR is defined by the Relative Biological Effectiveness (RBE), Quality Factor, Q, and Radiation Weighting Factor, wR. (ICRP, 2003).

Gy (joule/kg) can be used for any type of radiation. Gy does not describe the biological effects of the different radiations. Weighting factors are dimensionless multiplicative factors used to convert physical Dose equivalent is defined as H = D*Q, where D is the dose and Q is the quality factor taken from the table above. Dose equivalent is supposed to approximate the biological effect of different types of radiation so the Sv (or rem) is used as the unit to regulate the amount of dose an individual receives, rather than rads. Which of the following radiation units is determined by the quality factor (QF)? a.

Quality factor. The factor by which the absorbed dose (rad or gray) is to be multiplied to obtain a quantity that expresses, on a common scale for all ionizing radiation, the biological damage (rem or sievert) to an exposed individual. It is used because some types of radiation, such as alpha particles, are more biologically damaging internally than other types.

Quality factors translate the effects observed due mainly to gamma rays from the atomic bomb into the effects predicted from long term exposure to space radiation. Understanding how to achieve these translations requires consideration of the physical constitution of tissues and organs, and an understanding of the time course of their response Radiation Absorbed Dose (RAD) is the accepted unit of measurement of absorbed dose in tissue. 1 RAD represents 100 ergs of energy imparted per gram of material at the place of exposure.

A radiation weighting factor is an estimate of the effectiveness per unit dose of the given radiation relative a to low-LET standard. Gy (joule/kg) can be used for any type of radiation. Gy does not describe the biological effects of the different radiations.

Farlex Partner Medical Dictionary © Farlex 2012 The absorbed dose of specific types of radiation is multiplied by a "quality factor" to arrive at the dose equivalent. The SI unit is the sievert (SV), but the rem is commonly used. Rem is an acronym for "roentgen equivalent in man." One rem is equivalent to 0.01 SV. When exposed to X- or Gamma radiation, the quality factor is 1. In considering the present state of radiation units for protection purposes, we shall start from proposals made by the International Commission on Radiation Units and Measurements.
