Increased use of the cyclotron by the Massachusetts General Hospital for cancer treatments has raised radiation levels to the point where the Harvard Committee on Radio Isotopes recommended earlier this year that a new location be found for the Oxford St. Day Care Center...
Jacob Shapiro, radiation protection officer for the University, said yesterday the cyclotron has been letting off about five millirems of radiation, measured in exposure units. He said the amount has not been proved harmful and is actually negligible because there are always about
Died. John Ray Dunning, 67, pioneering American nuclear physicist; of a heart attack; in Key Biscayne, Fla. Dunning directed the 1939 experiment at Columbia University's cyclotron in Manhattan that confirmed the findings of scientists in Germany and elsewhere about the possibility of controlled atomic fission. "Believe we have observed new phenomenon of far-reaching consequences," he scrawled in a diary. Dunning's later research showed that Uranium 235 was the most fissionable isotope, a discovery that led to the gas-diffusion method of refining U-235, currently used in nuclear bombs and most atomic power plants...
...Central University of Nanking, receiving a Bachelor of Science degree in 1936. The same year, she came to the United States to do graduate work at the University of California under Ernest O. Laurence, who won the 1939 Nobel Prize in Physics for his invention of the cyclotron...
...Mailer. Thinned down from prepublication fasting, Mailer looked a bit like a quizzical coyote as he listened to a speech about his favorite writer by John Leonard, editor of the New York Times Book Review. Warming to his subject, Leonard variously described Mailer as a "libidinal compost heap," "a cyclotron run amuck," and a writer who wears his books "like a string of grenades." Then he got round to comparing Mailer (favorably) to Dickens, D.H. Lawrence and Don Quixote. The author thanked Leonard for his mellifluous praise but genially observed that, however gratifying, it was all "too little...
