Dose Coefficients for Intakes of Radionuclides by Members of the Public: Part 1

"This publication is the first in a series of publications giving age-specific dose coefficients for members of the public for environmental intakes of radionuclides by inhalation and ingestion. This series replaces the Publication 56 series, updates some data from Publication 119, and is in addition to the Occupational Intakes of Radionuclides series. The revised dose coefficients have been calculated using the Publication 100 Human Alimentary Tract Model and the Publication 130 revision of the Human Respiratory Tract Model. Revisions have also been made to many of the models that describe the systemic biokinetics of radionuclides absorbed to blood, making them more physiologically realistic representations of uptake and retention in organs and tissues, and of excretion. Changes introduced in Publication 103 have been implemented to: the radiation weighting factors used in the calculation of equivalent doses to tissues; the tissue weighting factors used in the calculation of effective dose; and the separate calculation of equivalent doses to males and females with sex-averaging in the calculation of effective dose. Reference anatomical computational phantoms, such as those in Publications 110 and 143 (i.e. models of the human body based on medical imaging data), have replaced many of the composite mathematical models used for previous calculations of organ doses. Dose calculations were also improved by using updated radionuclide decay data in Publication 107, and specific absorbed fraction data in Publications 133 and 155."
