BERGE: Not entirely, no KOHN: All right. Well, when Dr. Stone left the AEC and wentback to his post at the UCSF as head of the Departmentof Radiology, a decision had been made by the AEC to have a numberofnational laboratories. The AEC was supporting Oak Ridge, Brookhaven, Argon and then on a very much smaller scale, they decided that Stone should have a high-energy unit for therapy in San Francisco. Dr. Stone chose the highest energy machine possible with reasonable planning; the General Electric Co. had built a 70 MeV synchrotron, and they would build him a second one. So a special building was constructed to house the machine behind the main USCFbuildings;it would also contain some laboratory space. Have youseenit? BERGE: No. KOHN: The Laboratory was completed around 1950-1951. The synchrotron wasa very large machine; it had to be installed, made to work reliably, and calibrated. Dr. Gail Adams cameto be the physicist in charge of the machine, andhe also instructed the radiology residents in radiological physics. Dr. Stone asked meif I would head thelittle radiation biology unit, and I accepted. Of course, I was working there some years before the machine wastreating patients. I had a small group of associates consisting of Bob Kallman, who hasjust retired at Stanford, where he becamethe professor of radiation biology. BERGE: Howdo youspell his last name?
