Dear Bill:

(:

I have reviewed your draft letter of December 17, 1976 to Dr. James L. Liverman relating the TTG recommendations concerning transuranic contamination of
Bikini residents. The letter is right on target, however, I would like to see {
several points clarified or added as noted below:

I would like to see the last paragraph changed to read as follows: "In
considering these questions, the TTG felt somewhat handicapped in that a concise
but comprehensive summary of information on Bikini was not available. Livermore,
Brookhaven, HASL, the University of Washington and perhaps other Tabs have collected
data which could be useful in assessing the current levels of contamination on
Bikini. It would be appropriate to have all of this data brought together, summarized, interpreted and used as partial guidance for establishing a long range
\ronsterns program and estimating health risks for Bikini residents.”
