(Biospheric model validation in urban, terrestrial, and aquatic environments, Budapest, Hungary, Vienna, Austria, Neuherberg, and Schmallenberg, W. Germany, April 25--May 12, 1988): Foreign trip report

Drs. Blaylock, Hoffman, and Bartell attended the Sixth Biospheric Model Validation Study (BIOMOVS) meeting in Budapest, Hungary. BIOMOVS is an international cooperative effort to test models designed for calculations of environmental transfer and bioaccumulation of radionuclides and other trace substances. The participants from ORNL served as task group leaders, sessions chairmen, scientific consultants, and contributors to modeling efforts and task discussions at this meeting. BIOMOVS is completing the third year of a 5-year study; many of the tasks assignments are nearing completion, and draft reports are being written. Three final reports were available for distribution. After the BIOMOVS meeting at the invitation of the International Atomic Energy Agency (IAEA), Dr. Hoffman attended a Coordinated Research Program meeting entitled ''Model Validation in the Urban, Terrestrial, and Aquatic Environments'' and a technical consultants meeting to help formulate plans for the IAEA to continue studies similar to the BIOMOVS effort. Dr. Bartell was invited to Gesellschaft fuer Strahlen-und-Umweltforschung (GSF) in Neuherberg, Federal Republic of Germany, and to Fraunhofer Institut in Schmallenberg, Federal Republic of Germany to present seminars on research concerning current issues in ecological risk analysis.
