New ICRP Draft Report for Comment

The ICRP has made a new draft report available for comment - Human Alimentary Tract Model for Radiological Protection. A Task Group was appointed by Committee 2 to review the dosimetric model of the gastrointestinal tract used in ICRP Publication 30 (1979) and recommend revisions. The revised model described in this publication is applicable to children as well as adults. The new model will be used in future ICRP publications giving dose coefficients for radionuclide intakes following either occupational or environmental exposures. It will also be used in publications concerned with the interpretation of bioassay measurements.
