Radiation weighting factor
The Radiation Weighting Factor is used to modify the Absorbed Dose
(Gray
) by multiplying to obtain a quantity called the Equivalent Dose
(Sv
). It is defined by the ICRP
and used because some types of radiation, such as Alpha Particles
, are more biologically damaging internally than other types such as the Beta Particle
. The factor is similar to the Quality Factor
determined by the US Nuclear Regulatory Commission (NRC).
