BERGE: Notentirely, no. KOHN: All right. Well, when Dr. Stone left the AEC and went back to his post at the UCSF as head of the Departmentof Radiology, a decision had been made by the AEC to have a numberof national laboratories. The AEC was supporting Oak Ridge, Brookhaven, Argort/and then on a very much SL 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 wasconstructed to house the machine behind the main USCF buildings;it would also contain some laboratory space. Haveyouseenit? BERGE: No. KOHN: The Laboratory was completed around 1950-1951. The synchrotron was a very large machine; it had to be installed, made to work reliably, and calibrated. Dr. Gail Adams cametobe the physicist in charge of the machine, and healso 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 someyears before the machine was treating patients. I had a small group of associates consisting of Bob Kallman, whohasjust retired at Stanford, where he becamethe professor of radiation biology. BERGE: How do youspell his last name?
