skos:definition "Multiplier of the 'equivalent dose' to an organ or tissue used for 'radiation '<br/>
'protection' purposes to account for the different sensitivities of different organs <br/>and tissues to the induction of 'stochastic effects' of 'radiation'. (From Ref. [1].)<br/>
The 'tissue weighting factors' recommended by the International Commission <br/>on Radiological Protection for calculating 'effective dose' are:<br/>

a The weighting factor for the colon is applied to <br/>
the mass average of the 'equivalent dose' in the <br/>walls of the upper and lower large intestine.<br/>
b For the purposes of calculation, the <br/>
remainder is composed of adrenal glands, <br/>brain, extrathoracic region, small intestine, <br/>kidney, muscle, pancreas, spleen, thymus <br/>and uterus. In those exceptional cases in <br/>which the most exposed remainder tissue <br/>receives the highest <i>committed equivalent <br/>dose</i> of all organs, a weighting factor of 0.025 <br/>shall be applied to that tissue or organ and a <br/>weighting factor of 0.025 to the average <i>dose<br/></i>in the rest of the remainder as defined here.<br/>" (en)
