E. T. Lessard and”-W. L. Robison August 17, 1984 Page 2 Calculate 1. Annual dose equivalent to bone surface and bone marrow at end of about seven years residence on Bikini. 2. 50-year committed dose equivalent to bone surfaces and to bone marrow resulting from continuous intake at same rate experienced by people who lived on Bikini for seven years. 3. The Pu burden at the end of seven years residence on Bikini. If these i)ose serious ~roblems for You, Please feel free to qet on the phone with each other and agree upofiwhat doses you will cal~ulate and the models to be used. I bel. eve it is important to establish that dose equivalents calculated on the basis of estimates of food and air intake are comparable to those calcu” ated from bioassay data. If this cannot be done then we will have to look for serious errors in our models. I look forward to seeing you the 29th. Sincerely, ‘1 ,?,,C//; 6(;/’& ,-~:~. J.
