Organs of interest would be whole body, lung and bone. Others could be added at minimal cost. 7) In addition to the four nuclides you requested (Sr-90, CS-137, Pu-239 and Am-241) several others could be added, if data were available, at minimal cost. 8) Under the time and cost constraints, we could not verify the accuracy or reasonableness of the input data received from LLL, nor could we verify that all important pathways of exposure had been identified. If you have any questions on the calculations before you leave, call Joe Soldat on 942-4116 (work) or 943-4123 (home), or from Washington, DC (FTS: 444-4116). Ed Watson may not be in town next week.
