A research consortium comprised of representatives from several universities and national laboratories has been established as part of this on-going project to generate internal and external dose conversion coefficients for radionuclides produced in spallation neutron sources. Information obtained from this multi-year study will be used to support the siting and licensing of future accelerator-driven nuclear initiatives within the U.S. Department of Energy complex, including the Spallation Neutron Source (SNS) and Accelerator Production of Tritium (APT) Projects. Determination of these coefficients will also fill data gaps for several hundred radionuclides that exist in Federal Guide Report No. 11 and in Publications 68 and 72 of the International Commission on Radiological Protection (ICRP).

Representatives from the Working Group established in Year 1 have developed methodology to generate dose coefficients from radionuclides produced during the spallation process. Dose coefficients have been generated using this methodology for a select few radionuclides. Personnel will build on this progress to generate dose coefficients for approximately 120 radionuclides during Year 2.
