Radionuclide biokinetics database

One task of the EULEP-EURADOS Action Group on Parameter Values for the Human Respiratory Tract Model was to collate published information on experimental studies of the biokinetics after inhalation of important radioactive compounds encountered in occupational exposure. A database was built, which is effectively an annotated bibliography, but the electronic format facilitates extension, updating, and information retrieval. It consists of linked tables of references and experiments, with details and comments on the material, procedures and results. The database contains information from 103 references on 218 inhalation, 35 ingestion and 35 injection experiments. The latter are included because they often complement inhalation studies. It is planned to extend the database, to address ingestion and injection explicitly, and to provide Internet access. Three types of users are envisaged: groups developing standards for internal dosimetry, scientists conducting research on radionuclide biokinetics, and health physicists assessing the consequences of accidental intakes.
