Sage Publications ICRP Publication 133: The ICRP Computational Framework for Internal Dose Assessment for Reference Workers: Specific Absorbed Fractions (Annals of the ICRP)

This report provides the technical basis for SAFs relevant to internalised radionuclide activity in the organs of the reference adult male and reference adult female as defined in Publications 89 and 110. SAFs are given for uniform distributions of monoenergetic photons, electrons, alpha particles, and fission-spectrum neutrons over a range of relevant energies. Electron SAFs include both their collision and radiative components of energy deposition. SAF data are matched to source and target organs of the biokinetic models of the OIR publication series. The document further outlines the computational methodology and nomenclature for assessment of internal dose in a manner consistent with that used for nuclear medicine applications. Numerical data for particle specific and energy dependent SAFs are given in electronic format for numerical coupling to the respiratory tract, alimentary tract, and systemic biokinetic models of the OIR publication series.
