The travelers participated in a meeting of the International Commission on Radiological Protection (ICRP) Task Group on Age-Dependent Doses to Members of the Public from Intakes of Radionuclides, held April 22--26, 1991, in Hungerford, England. The main purposes of the meeting were (1) to make final selections of proposed age-specific gastrointestinal absorption fractions and biokinetic models for S, Co, Ni, Zn, Sr, Mo, Tc, Ag, Te, Ba, Ra, Pb, and Po and (2) to rewrite a preliminary draft of Part 2 of ICRP Publication 56, which addresses age-specific doses from ingestion of important radioisotopes of these elements. During the week the Task Group was able to complete these tasks, except for a few unresolved questions on models for Ni, Zn, Mo, and Te. It is anticipated that the remaining details can be worked out by correspondence and that a revised draft of this report can be presented to Committee 2 of the ICRP at their meeting in July, 1991. On Wednesday afternoon, April 24, Mike Bailey of the National Radiological Protection Board (NRPB) of Great Britain discussed implications of a new respiratory tract model developed by another ICRP task group and intended to replace the current ICRP respiratory tract model, which has been used for about 25 years. On Thursday, April 25, the Task Group visited the NRPB. Workers at the NRPB demonstrated their computer implementation of the proposed ICRP respiratory tract model. The travelers met with members of the NRPB and exchanged ideas on the best ways of implementing the proposed lung model and some equally complex biokinetic models appearing in recently published ICRP documents or proposed for use in future documents.
