These documents are summaries of the body-burden data obtained since your review of the program. I have included an abstract of a talk on thyroid absorbed dose which has been planned for July 1983. Dose re-assessment methods and results will be presented at that time, and the incidence of thyroid nodules will be evaluated in terms of these dose estimates. Thank you for the copies of the books, and for your continued interest. Sincerely, Cdivar ch Tsar ol. Edward T. Lessard ETL/ce Enclosures cc: J. Baum S. Marks, M.D.
