The Pu burden at the end of 7 years (or for that matter for any of the first 9 years) is listed in Table 4 of the material [ sent you earlier. At 7 y the body burden is 4000 to 5000 fCi for the given set of assumptions listed in the footnote of the table. | realize these doses are very different from those you received from Ed Lessard and | guess that is why we are going to meet. As you can see from the material [| have sent you, | also do not understand the observed urine concentrations and associated doses when | make a comparison based on our measured soil and vegetation concentrations, the diet models and current Pu models. | look forward to meeting with all of you to try to resolve this problem. If there is any more | can do to supply additional data or calculations, please give me a call. Best regards, BAL William L..
