ICRP Publication 88

Doses to the Embryo and Fetus from Intakes of Radionuclides by the Mother

In its Publications 56, 67, 69, 71, and 72, ICRP has provided age-specific biokinetic models and, using those models, compiled dose coefficients (doses per unit intake) for intakes of radionuclides by members of the public. Committed effective doses for the inhalation or ingestion of radionuclides by workers who are occupationally exposed were given in Publication 68 based on the most recent dosimetric and biokinetic models for adults.

The present report complements that series by addressing doses to the embryo/fetus after intakes of radionuclides by a female member of the public or a female worker, before or during pregnancy. Ingestion and inhalation of selected radionuclides of the 31 elements for which age-dependent biokinetic models were provided in the previous reports are considered.
