Liverman Office of the Assistant Administrator for Environmental and Safety Energy Research and Development Administration Washington, D.C. 20545 Dear Jim: The Transuranium Technical Group met in Washington, D.C. on December 8, 1976 to review the data which suggest the possible contamination of the inhabitants of Bikini with plutonium. The TTG views the issue of transuranium element contamination of present and future residents of the Bikini atoll as consisting of four major questions: 1. Do the residents of Bikini have plutonium burdens higher than those of other persons living in the same latitude? 2. If the Bikini residents do have increased plutonium burdens, what r is the source of these burdens? 3. What future transuranic body burdens are projected for current residents and their descendants? 4. What potential health risks are associated with current and projected transuranic burdens of the Bikini residents?
