Mrs. Ruth Clusen 2 May 29, 1979 organ burdens by year for individual radionuclides that are expected to be significant contributors to the total dose to people. Further, estimates of dose by year should be prepared for each individual radionuclide and each source of exposure in addition to aggregate annual and cumulative dose. Whenever possible, some estimate should be made of the expected uncertainties in radionuclide burdens and dose. Provision should be made for rigorous documentation of all dose and risk calculations. Because of the importance of the dose and risk estimates, provision should be made for Livermore to provide their input data to other institutions allowing the other institutions to verify the Livermore dose and risk estimates. Concurrent with development of the post-cleanup dose and risk estimates a detailed plan should be developed for medical and radiological followup activities in Enewetak. This plan should clearly indicate the objectives of each proposed activity, the responsible party and how the objective will be achieved. Where practical, there should be linkage between the postcleanup dose and risk assessment and the medical and radiological followup. For example, plans for whole-body burden measurements and urinalysis for 90Ssr and Pu should link back to estimated body burdens and urinary excretion of radionuclides. The plans for conducting a post-cleanup dose and risk assessment and for medical and radiological followup are obviously dynamic in nature. They will change as new information is obtained. The Advisory Group is available to review the plans and offer comments on them as they are developed and implemented. The Advisory Group recommends increased participation by statisticians in LLL's post-cleanup transuranic and fission product dose assessment for the Enewetak Atoll. At the present time statisticians do not appear to be involved in the dose assessment effort other than to provide LLL with environmental concentration data for their data bank. Specifically, statistician activities should include (a) statistical analysis and summary of each island's data for inclusion in the dose assessment report, (b) assisting LLL modelers to place estimates of precision on dose estimates to the extent possible, (c) reviewing dose assessment calculations and the final dose assessment report to verify that soil concentration and other data are used and presented appropriately, and (d) any other activities necessary to assist LLL in providing a dose assessment of the highest scientific standards. Although not discussed during the meeting, some members of the Advisory Group have expressed concern that procedures for certifying completion of the cleanup have not been agreed upon. This should receive immediate attention. 2.
