RADIATION WEIGHTING FACTORS (ICRP 60)<br />
2<br />
Type and Energy Range <strong>Rad</strong>iation Weighting Factor, W R<br />
Photons, all energies 1<br />
3<br />
Electrons and muons, all energies 1<br />
Neutrons, 20 MeV 5<br />
Protons, other than recoil protons, energy > 2MeV 5<br />
Alpha particles, fission fragments, heavy nuclei 20<br />
1<br />
All values relate to the radiation incident on the body or, for<br />
internal sources, emitted from the source.<br />
2<br />
The choice of values for other radiation is discussed in Annex<br />
A of Publication 60.<br />
3<br />
Excluding Auger electrons emitted from nuclei bound to DNA<br />
