Lessard to Thiessen, MD dose equivalent estimates. -3- December 17, 1980 This project is ongoing and relates directly to contemporary radiation protection operations. For example, we are currently focusing on infant and small child dosimetric parameters, such as absorbed fractions and daily activity ingestion rates, which have impact on both retrospective and prospective dose assessments. This letter is meant to acquaint you with some of the activities of members of the Marshall Islands Radiological Safety Program. We, Jan Naidu, Robert Miltenberger and myself extend our best regards in your new role as Director of the Human Health and Assessments Division. Additionally, I would like to meet with you briefly in the future in order to update our progress. I hope that it will be convenient for you if I stop in during my next visit to DOE headquarters which will occur after the holidays. Sincerely, Edawana Pe asa rcel Edward T.
