...Lawrence is so loath to part with his cyclotron is that he is now engaged in the most significant problem of his career: the effect of neutron rays on cancer of human beings. The cyclotron whirls ions of heavy hydrogen (deuterons) between the poles of a huge electromagnet, then hurls them into a drumlike vacuum chamber. When they are charged with nearly eight million volts of energy, the ions are shot against a target of light metal, usually beryllium. The bullets knock out streams of neutrons, tiny particles about the same weight as protons but carrying no electric charge...
...story concerned University of California's Ernest Orlando Lawrence, No. 1 U. S. experimenter in artificial radioactivity, whose 85-ton electromagnet frequently makes scientific news. Solemn young Dr. Lawrence would be horrified to find himself associated with the "death-rays"' of lurid pseudoscience. Actually he was only protecting himself and hi's co-workers from the effects of a beam of 10,000,000 neutrons a second generated with the help of his electromagnet for use in straightforward atomic experiments...
Microanalysis. By means of capillary tubes which require microscopes to tell when they are properly filled and a tiny iron-filled glass ball agitated by an electromagnet to stir the contents of the tiny glass vessels, Drs. David Glick and Gerson Ravinson Biskind of San Francisco made micro-analyses of microscopic bits of human tissue. Thus they learned that the middle part of pituitary gland contains Vitamin C (found in oranges, lemons, tomatoes, peppers, spinach) in more concentrated form than any plant or other animal tissue. The fore part of the pituitary, the adrenals and the ovaries also contain heavy...
Artificial Radium. By means of a powerful electromagnet Professor Ernest Orlando Lawrence of Berkeley can in ten hours' operating time instill as much radiant energy into a speck of common table salt as $2,500 worth of natural radium contains. The chief difference is that whereas natural radium, a deadly poison, will retain its radioactivity for thousands of years, radioactive table salt will lose all its potency within a few hours. During the period of its radioactivity, however, such table salt may do as much medical good as natural radium, and probably without harmful effects...
Radiant Copper. Dr. Ernest Orlando Lawrence, 33, wears octagonal spectacles and harries the atom with an 85-ton electromagnet in a ramshackle old building on the University of California's campus. Dr. Lawrence and his associates have done the most intensive work in the U.S. on artificial radioactivity. Lately the young physicist succeeded in inducing radioactivity in sodium. Since common salt contains sodium, the prospect immediately arose of injecting harmless but radioactive saline solutions into the human body as a cancer remedy. Few weeks ago Dr. Lawrence was appointed a research consultant of Columbia University's Crocker Institute...
