Doses from Radiation exposure
|
The Task Group on Internal Dosimetry (INDOS) is currently engaged in revision of biokinetic models, for use in the recalculation of dose coefficients for the inhalation and ingestion of radionuclides, first for workers and subsequently for members of the public. It is intended to replace Publications 30 and 68, that give biokinetic data and dose coefficients for occupational intakes of radionuclides by inhalation and ingestion, and Publications 54 and 78, that give information for bioassay interpretation, with a single series of publications. The new ICRP model of the human alimentary tract will be used and revisions will be made to the Human Respiratory Tract Model. A separate report will consider intakes of radionulcides through wounds, following publication of a wound model by the US National Council on Radiation Protection and Measurements (NCRP). Doses will be calculated using revised nuclear decay data and new anatomical models (see Task Group on Dose Calculations, DOCAL).
