"The radiation weighting factor (WR) is a dimensionless constant that accounts for the relative biological effectiveness (RBE) of various types of ionising radiation."
"The radiation weighting factor is used to calculate the equivalent dose (HT) by the following equation:"
"Absorbed dose (DT) x radiation weighting factor (WR) = equivalent dose (HT)"
"WR = 1: photons, electrons"
"WR = 2: protons"
"WR = 20: alpha particles, fission fragments, heavy ions"
"WR = variable: neutrons (determined by complex equations)"
