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: we ote. ©wig aS 1, ye You note that "if the revised projections indicate body burdens a is 6 (per sonally feel this should be changed to read — "indicate body burgens 0Cnnano-“ie ‘- eeewv curies or more, then in vivo counting of al] residents is urged.” nally doubt that burdens ofTessthan 10 nanocuries can be measured with any degree ofst Validity, a 6K oe vl bee > especially at ilTy t 3) Bikint.

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.” jeeae * Sincerely, cue OD ' 6AE2 ete Ae ALOE 7 Cet C¢ Roger 0.
