...amazing number of shabbily dressed persons from all parts of Europe who have managed to get to Paris for this high-powered intellectual carnival. Among French scientists who have collaborated to make and staff the Palace of Discovery is Mine Curie-Joliot, eminent chemist daughter of the discoverer of radium. One completely round room exhibits the mathematical symbol pi (ordinarily figured as equal to 3,1416) worked out to such a length that the resulting decimal winds three times around the room. At intervals is heard a phonograph transcription of a short lecture by one of France's greatest...
...land was recently in litigation, was cleared a few weeks ago after the case reached the California Supreme Court. Last week it looked as though Mrs. Bishop's troubles were over. Newsstories from Southern California made it appear that Mrs. Josie Bishop owns an extremely rich deposit of radium-bearing ore-one of the richest, in proportion of radium to the ton, ever discovered...
...same principle underlies a technique, explained last week, for ferreting out defects in thick masses of steel. At the convention of the American Society for Testing Materials in Manhattan, Physicist E. V. Lange of Radium Chemical Co. demonstrated with a capsule containing one-tenth of a gram of radium. Gamma rays shooting out at a million or more volts passed through steel castings a foot thick, photographed the interior structure on X-ray films 10 by 12 in. in size. Tested by this method are steering posts of ships, turbines, valves, high-pressure steam pipes. Dr. Lange reported that...
...number of years physicists and engineers have been working on the problem of providing a source of very high voltage X-Rays which would approximate in wave length the gamma rays of radium, and which could be produced in intensities equaling the output of several hundred grams of this element...
...Radium would offer an ideal source for the external application of short, penetrating rays, but even when several grams of the element are available, the intensity of radiation is so small that the distance between the patient and the applicator can not, with economy, be made sufficiently great to deliver an adequate does to a deep-seated tumor...
