Abstract

In early 1986, the DOE/OHER Task Group on Modeling and Scaling was formed. Membership on the Task Group is drawn from staff of several laboratories funded by the United States Department of Energy, Office of Health and Environmental Research. The primary goal of the Task Group is to promote cooperation among the laboratories in analysing mammalian radiobiology studies with emphasis on studies that used beagle dogs in lifespan experiments. To assist in defining the status of modelling and scaling in animal data, the Task Group served as the programme committee for the 26th Hanford Life Sciences Symposium entitled Modeling for Scaling to Man held in October 1987. This symposium had over 60 oral presentations describing current research in dosimetric, pharmacokinetic, and dose-response modelling and scaling of results from animal studies to humans. A summary of the highlights of this symposium is presented. The Task Group also is in the process of developing recommendations for analyses of results obtained from dog lifespan studies. The goal is to provide as many comparisons as possible between these studies and to scale the results to humans to strengthen limited epidemiological data on exposures of humans to radiation. Several methods are discussed.
