  1. The gastrointestinal absorption of the actinide elements.

    Article - En anglais

    The greatest uncertainty in dose estimates for the ingestion of long-lived, alpha-emitting isotopes of the actinide elements is in the values used for their fractional absorption from the gastrointestinal tract (f1 values).

    Recent years have seen a large increase in the available data on actinide absorption.

    Human data are reviewed here, together with animal data, to illustrate the effect on absorption of chemical form, incorporation into food materials, fasting and other dietary factors, and age at ingestion.
