↵a Remainder organs are: adrenals, extrathoracic region, gall bladder, heart, kidneys, lymphatic nodes, muscle, oral mucosa, pancreas, prostate or uterus/cervix, small intestine, spleen, thymus. For remainder organs a tissue-weighting factor of 0.05 is assigned according to the IRCP 103 version. The effective dose for the extrathoracic region and the oral mucosa, respectively, corresponds to the mean dose on remainder organs.
