Progrese Report ~3- April 1, 1952. Plans for research programs to be carried out in this hospital are well advanced and will include among items of major interest to the Commission studies on individuals who received radium therapeutically and studies on the protective effects of shielding various organs during exposure to whole body radiation with particular emphasis on efforts to obtain an active protective substance from normal tissues. Research on Beryllium Poisoning: The University of Rochester Atomic Energy Project has developed a method for the production of a beryllium oxide fume by using a beryllium metal arc burning in an oxygeneargon atmosphere. The fumes consist of extremely smali particles approaching 0.01 microns. Preliminary animal exposure studies showed that reasonable amounts of the material were deposited and retained in the lung. The finding of small quantities of beryllium deposited in the femr and none in the pulmonary lymph nodes appears to suggest that removal of the deposited material from the lungs is by solubility rather than phagocytosis. (See report UR-27h) This is a real step forward in the Commission's efforts to solve the problem of chronic beryllium poisoning. Control of Beryllium Hazards: The revised "Recommendations for Control of Beryllium Hazards", which are essentially the same as those issued last year, were sent by memorandum from the General Nanager to Managers of Operations Offices and Washington Division Directors on August 10, 1951. Production of Ultra-Violet Light by Ionizing Radiation: In a report from the UCLA Atomic Energy Project (UCLA@127), Dr. Andrew He Dowly has been ahle to demonstrate the production of ultra-violet light in distilled water by ionizing radiation using the gamma rays of radium as a source. The production of ultra-violet light by lonising radiation has been suspected for some time but this is the first time that this process has been demonstrated.
