The radiation weighting factor is a dimensionless factor to derive the equivalent dose from the absorbed dose averaged over a tissue or organ, and is based on the quality of the radiation.
from ICRP Publication 123, 2013
A dimensionless factor by which the mean absorbed dose in an organ or tissue, DT, is multiplied to reflect the relative biological effectiveness of high-LET radiations compared with low-LET radiations. The product of wR and DT is the equivalent dose in the organ or tissue T.
