Task Group 95
Internal Dose Coefficients
Under Committee 2
The objectives of this TG are to continue and finish the work initiated by INDOS on the revision of the ICRP 30 series. The deliverables are report series providing dose coefficients for occupational (OIR) and public intake of radionuclides.
The work of this Task Group over the last few years was dedicated to the revision of the biokinetic models following inhalation and ingestion of different chemical forms of elements and their radioisotopes by workers. Revisions have also been made on many models for 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. All these data were published in 5 OIR reports (ICRP Publication 130, 134, 137, 141, 151) together with new dose coefficients and data for the interpretation of bioassay measurements.
The current task of this TG is to revise the biokinetic and dosimetric models for the members of the public. Biokinetic models developed in the workers series will be modified to take into account specific chemical forms from the environment and different age groups. For embryo and fetus, new specific models will be developed to replace the former CF:CM concentration ratio. Similarly to the OIR Series, the TG will produce dose coefficients for easy calculation of dose after intake at different age, including nursing infant, embryo and fetus.
