The new recommendations of the International Radiological Protection Commission (ICRP) -103 have changed the method of calculating the neutron radiation weighting factor and the tissue weighting factor value that were defined in earlier ICRP recommendations (ICRP, 2007; ICRP, 1991; ICRP, 1996)....

It is worth noting that absorbed organ doses are relatively similar between these two tissues despite the difference in tissue weighting factors according to ICRP publication 103 [Citation26]. The weighting factor for salivary glands is 0.01 and for oral mucosa 0.12 (is included in the remaining ...
ICRP (2007) for radiation protection of humans are 1.0 for photons, electrons and muons, 2.0 for protons and charged pions, 20 for alpha particles, fission fragments and heavy ions, and 2–20 for neutrons of various energies. These values of the radiation weighting factors are “… selected ...

The ICRP Publication 103 (ICRP, 2007) presents data on nominal risk coefficients, relative detriment, and tissue weighting factors for calculating and applying effective dose. However, the data does not consider variations in risk based on age, sex, and population characteristics, except for distingu...
