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.

dose estimation task.

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,

an evaluation of these post cleanup data with data obtained prior
