Conclusions and Recommendations ). Dose Assessment Report The advisory Group does not believe the present draft of “Assessment of Potential Doses to Populations from the Transuranic Radionuclides at Enewetax" is an acceptable basis for decisions regarding cleanup criteria and eventual resettlement of the atoll] for the following reasons: A. Data base: The data used in the dose assessment calculations appear to be inadequate and introduce into the dose calculations a large uncertainty which is not identified. Some of the data used are extrapolations from data collected at other sites and under different conditions from those at Enewetak, thus the data may not be applicable, B. Basic Assumptions: The assumptions used in deriving the dose estimates appear to have been selected mere for the purpose of maximizing the range of doses that persons inhabiting the atoll] could receive than for estimating most probable or reasonably expected doses. On the other hand, doses were estimated for what appears to be an average population, rather than for different population groups (e.g., infants, children, young adults, aged, etc.), In several cases the basic assumptions are not given and in others, unpublished and unsubstantiated conclusions served as a basis for assumptions used. An example is the gastrointestinal absorption factors. C. Approach: Dose estimates are not obtained for actual average soil concentrations as they presently exist on the islands. That is, the estimated average surface (0-3 cm) concentrations over 1/4 or 1/2 hectare areas obtained using the IMP and soil samples are not
