Tissue Weighting Factors ( ICRP 60 -> 103 - 116 )

• Tissue weighted sum of equivalent doses in all specified organs and tissues of the body • w T is the tissue weighting factor by which the equivalent dose in an organ or tissue T is weighted to represent the age- and sex-averaged relative contribution of T to overall radiation detriment from stochastic effects (ICRP, 1991) • Effective dose is a quantification of risk for stochastic effects
