Thiessen, M.D. U.S. Department of Energy Office of Health & Environmental Research ER-71 Washington, DC 20545 Dear Dr. Thiessen: Enclosed please find a copy of "Protracted Exposure to Fallout: The Rongelap and Utirik Experience” and a draft of “Thyroid Absorbed Dose For Rongelap and Utirik Residents". The protracted exposure document was accepted by Health Physics. I have recently retumed the proofs to the Health Physics Journal and I anticipate it to be published within a few ‘months. The draft document on thyroid absorbed dose has not been peer reviewed, and only two sections of the four section report are included. TI am sending it to you because it is a tabulation of information perti- nent to the activities of the Litigation Support Working Group. Please excuse any omissions, errors or unit inconsistencies in this draft. In response to your question about future activities in the Marshall Islands, I am enclosing a detailed five-year plan (1985 through 1989). This plan was prepared several weeks ago for Roger Ray in response to a list of questions set forth by the DOE Marshall Islands Planning Group. I feel these documents will be useful to the members of the working group and any comments will be appreciated. Best regards. age Sincerely, Edward T. Lessard ETL/ce Enclosures ce: TT. McCraw
