Reflections on Research Accomplishments

(1)John Lawrence, M.D., brother of Ernest O. Lawrence, was Director of the Division of Medical Physics at the University of California, Berkeley. He operated a clinic at Donner Laboratory, where he treated leukemia and polycythemia patients with radioactive phosphorus. For a colleague's recollection of Dr. Lawrence's clinic, see the interview with Dr. John Gofman (DOE/EH-0457), the sections "From Research to Laboratory Production of Plutonium," "Medical Treatments With Radioactive Phosphorus (32P)," "Conflict Between University of California San Francisco and Berkeley," "Heparin and Lipoprotein Research With Human Subjects," and "Radiophosphorus Therapy for Polycythemia Vera."

(2)"the bends." The bends are caused by tiny air bubbles released into tissue by a too-rapid decrease in air pressure after staying in a compressed atmosphere, such as the too-rapid ascent of a diver from deep in the sea to normal atmosphere at sea level. It is potentially fatal. Aviators experience a similar phenomenon in ascending too rapidly to high altitude in an unpressurized cockpit without the protection of a pressurized flightsuit. In this circumstance, aviators are at high risk of blacking out and losing control of their aircraft.

(3)an accelerator in which particles move in spiral paths in a constant magnetic field

(4)the U.S. Army Corps of Engineers organization set up to administer the development of the atomic bomb under the top-secret Manhattan Project. Originally headquartered in New York, it was moved to Washington, D.C., and finally to Oak Ridge, Tennessee, in the summer of 1943.

(5)established by an executive order June 28, 1941—six days after German troops invaded the Soviet Union. The OSRD's Director reported directly to the President and could invoke the prestige of the White House when dealing with other Federal agencies. The National Defense Research Committee, at the time headed by Harvard President James Conant, became an advisory body responsible for making research and development recommendations to the OSRD.

(6)The UC Radiation Laboratory was founded by Ernest Lawrence in 1936 on the campus of the University of California at Berkeley. Upon Lawrence's death in 1958, the lab's name was changed to Lawrence Radiation Laboratory. The name changed again, in 1971, to Lawrence Berkeley Laboratory, a National Laboratory under the U.S. Department of Energy.

(7)Joseph Hamilton, M.D., worked at Crocker Laboratory, then the site of a 60-inch cyclotron that he operated to produce radioisotopes in support of research and some medical diagnosis and treatment. Crocker was part of the Lawrence Radiation Laboratory. Hamilton is discussed in several transcripts of this series, notably in the interviews with John Gofman (DOE/EH-0457, June 1995) and Earl Miller (DOE/EH-0474, June 1995). Hamilton spent most of his career at the Lawrence Radiation Laboratory before dying prematurely of leukemia brought on, colleagues believe, by occupational exposure to radiation.

(11)U.S. physicist, 1901–1958; a pioneer in nuclear physics who built and operated (with M. Stanley Livingston and Milton White) the first cyclotron in 1930 on the Berkeley campus of the University of California; established University of California Radiation Laboratory in 1936 and served as its director until his death. His ingenuity and drive made the Berkeley-based Radiation Laboratory the unofficial capital of nuclear physics in the United States.

(31)Brain tumor patients were injected with a discrete amount of boron that was intended to deposit in the tumor. The tumor was then bombarded with a beam of neutrons that was directed to the boron in the hope of destroying the tumor.

(32)From 1951 to 1961, Brookhaven conducted boron neutron capture therapy on 45 patients. All were suffering from aggressive and otherwise untreatable types of brain tumors; all had received conventional radiation treatments. The therapy was unsuccessful. Patients so-treated generally lived only as long as patients with the same types of brain tumor who were treated with conventional radiation therapies. The work was funded by the U.S. Atomic Energy Commission. Source: Human Radiation Experiments Associated with the U.S. Department of Energy and Its Predecessors (213 pages), DOE/EH-0491, July 1995.

(33)Advances in technology that deliver higher concentrations of boron to tumor tissues for potentially improved therapy have brought about the return of boron neutron capture therapy. As a result, Brookhaven is currently involved in BNCT research and clinical trials.

(37)A pioneer in radiation therapy, Robert Stone, M.D., had conducted human radiation studies before World War II. He was an early researcher at the Lawrence Radiation Laboratory and became a major figure in radiobiology research. When Joseph Hamilton began operating his 60-inch cyclotron at Crocker Laboratory, Stone requested that fission products be made on the cyclotron and that their fate in mammals be systematically studied in small animals. That information would be used for radiation protection proposes. In 1942, while chairing the Department of Radiology at UC San Francisco's medical school, Stone was recruited to lead the Medical Division of the Manhattan Project, overseeing all biological, medical, and radiological protection research. Accordingly, he moved to the University of Chicago, where he served as Associate Director for Health under Arthur Compton. In the 1950s, after serving in the Atomic Energy Commission, Stone returned to his post at the UCSF as head of the Department of Radiology. Under Stone, UCSF acquired a 70-MeV synchrotron for conducting therapeutic research.

(38)A professor of Radiology at the University of Rochester (Rochester, New York), site of research involving plutonium and human subjects. Dr. Warren worked on the Manhattan Project in Oak Ridge as head of the medical section and headed an Intramedical Advisory Committee. After World War II, Dr. Warren became dean of the University of California, Los Angeles Medical School.

(39)Shields Warren, M.D., was Chief Pathologist at New England Deaconess Hospital and Professor of Pathology at Harvard Medical School. He joined the U.S. Navy Medical Department in 1939 and wrote with others on what was then known about radiation during World War II. Dr. Warren served on the first U.S. team to visit Hiroshima and Nagasaki after they were bombed with atomic weapons and was involved in creating what became the Atomic Bomb Casualty Commission. He was the first director of the AEC's Division of Biology and Medicine and, later, established his own cancer research institute at New England Deaconess Hospital. See "Recollections of Shields Warren" in DOE/EH-0471, Human Radiation Studies: Remembering the Early Years; Oral History of Radiologist Henry I. Kohn, M.D., Ph.D. (June 1995).

(46)In January 1978, the Soviet military space satellite, Cosmos 954, broke up during an uncontrolled reentry and scattered radioactive parts and fuel from its on-board nuclear power plant over a 483-mile-wide swath in the vicinity of Great Slave Lake in the Northwest Territories of Canada. Cosmos 954 was a Soviet radar ocean reconnaissance satellite (RORSAT) that had been sent into orbit to detect and track U.S. Navy aircraft carriers worldwide. Because the power demands of the satellite's radar exceeded the capability of solar power systems of the day, the Soviet low-earth-orbit RORSATs were powered by a small nuclear generator. The U.S.–Canadian North American Air Defense Command (NORAD) detected the fact that Cosmos 954's orbit had experienced unplanned decay, leaving the time of reentry predictable to within a day, but the point of reentry impossible to foretell. Civilian emergency service organizations in many parts of the world were placed on secret alert (without being told why) until after the reentry. The crash of Cosmos 954 in Canada resulted in no reported human injuries. Under an existing treaty, the Soviet Union was liable for all costs associated with cleanup. The event led to further international negotiation to limit the use of nuclear power in space. Later generations of Soviet RORSATs were redesigned to separate and boost their nuclear power plant into a higher parking orbit at the end of their mission life.

(78)Dr. Paul Aebersold established the administrative system for distribution of radioactive isotopes. After working on the Manhattan Project at Los Alamos, New Mexico, and Oak Ridge from 1942 to 1946, he served as director of the Atomic Energy Commission's Isotopes Division at Oak Ridge from 1947 to 1957. He retired as the Director of the AEC's Office of Isotopes Development in 1965. Two-and-a-half years later, he committed suicide. For additional information on Dr. Aebersold, see "Safety of the Nuclear Industry" in the interview with Merril Eisenbud (DOE/EH-0456, May 1995); "Remembrances of Personalities" in the interview with Earl Miller (DOE/EH-0474, June 1995); and "Oak Ridge Committees (Isotope Distribution, Human Use, et al.") and "Vanderbilt University Study of Pregnant Women and Iron-59" in the interview with Karl Morgan (DOE/EH-0475, June 1995).
