Review of Preliminary Working Dr Ay,of LLL! S "Reassessment of Enewetak Atoll P asi7 distributed June 4, 1979 TS My comments below are more detailed than in my memo to you dated June 12, 1979. To begin, I have three specific recommendations to make: 1. The authors should be required to include in their paper the equations used to estimate doses. In my view the dose assessment paper should be completely or nearly self contained either within the text or in appendices. A good example of the style I'm thinking of is the paper "Plutonium Transport and Dose Estimation Model" by W. E. Martin and S. G. Bloom, in Transuranium Nuclides in the Environment, IAEA, 1976, pp. 385-400. 2. Desert Research Institute statisticians at Las Vegas who are most familiar with the Enewetak radioisotope data should be used more effectively in assisting the authors with statistical aspects of the egG/F> directly with the authors, although effective assistance could perhaps be given from Las Vegas. My reasons for making this recommendation should be evident from my more detailed comments below. 3.

A complete statistical analysis of all data relevant to the dose assessment should be conducted and included as an appendix to the dose assessment paper. This analysis would serve as a basis for dose assessment procedures. Included would be diet survey methodology and data, soil data obtained during the post cleanup grid sampling, FS an evaluation of these post cleanup data with data obtained prior 3 to and during the cleanup operation, quality control samples, etc., $ j.e., a complete workup of relevant data.
