ICRP CD2: Database of Dose Coefficients: Embryo and Fetus
New to This Edition
In its Publications 56, 67, 69, 71, and 72, ICRP provided age-specific biokinetic models and dose coefficients (dose per unit intake of radioactive substance) for members of the public. Committed effective doses for inhalation or ingestion of radionuclides by occupationally exposed workers were given in Publication 68. A recent complementary report (Publication 88) addresses doses to the embryo/fetus after intakes by the mother before or during pregnancy. Selected radionuclides of 31 elements are considered. New biokinetic and dosimetric models for doses to the embryo/fetus are developed; they take account of transfer of radionuclides across the placenta, distribution and retention of radionuclides in fetal tissues, growth of the fetus, and photon irradiation from radionuclides in the placenta and maternal tissues. Human and animal data are used as available.
ICRP CD-ROM 2 gives inhalation dose coefficients for ten aerosol sizes (0.001, 0.003, 0.01, 0.03, 0.1, 0.3, 1, 3, 5, and 10 Ìm AMAD) as well as ingestion coefficients. Effective doses and equivalent doses for all important tissues for a range of post natal integration times (1, 5, 10 and 20 years) are given, together with the dose coefficients to age 70 years. In utero and post-natal doses are given, together with the total dose to offspring. Various intake scenarios are considered as in Publication 88.
The CD-ROM also contains substantial help files. These contain the text from ICRP Publication 88, and further information specific to the database.
