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).

Radiation is one of the important factors in evolution. It causes mutation, and some level of mutation is actually good for evolution
