compensation, After a full hearing, the judgment was reversed. Dr. Totter pointed out that with the marked reduction in support of Plowshare operations it was necessary to reevaluate the entire operation of the Biomedical Division at Lawrence Radiation Laboratory, Livermore. The ecology portion of the program was recently visited and reviewed. The chromosome studies will be reviewed in late September and the remainder of the program will be reviewed in November. It was noted that on October 9, 1970, there will be a 20th Anniversary celebration at the University of Utah AEC Project. Last spring the General Advisory Committee requestéd that the thermal effects data from Hanford be evaluated for potential usefulness in reactor siting in general. A committee is being formed to undertake this task. It is not clear whether they will have access to all data (some of which is classified). Dr. English is strongly in support of the position that they should see all the data and believes they can easily write an unclassified report. Dr. Bruner and Mr. Hollister of the DBM staff and Dr. Robert Miller from National Cancer Institute discussed in detail the recent publications of Dr. Alice Stewart in which she has estimated that 1 rad of exposure to human fetuses would result in an excess of 300 to 800 childhood cancers per million fetuses exposed. The arguments advanced by Bruner and especially by Hollister centered on methods and techniques of analysis which of themselves appeared inadequate to explain Stewart's remarkable findings. Material presented by Miller, however, cast very serious doubts on the validity of Stewart's claims. The data were provided by Mr. S. Jablon of ABCC and can be summarized as follows: If linearity of dose-response is assumed (as it is by Stewart) then the same tota! excess cancers would be seen whether 10° people were exposed to 1 vad or 10° people were exposed to 10 rads. The person-rads is the unit of interest in the denominator. A number of children were exposed in utero to bomb radiation in Japan. The numbers involved were approximately: Total Trimester L Person-rads 10,000 2 3 15,000 10,000 35,000 person-rads
