...first method of counting atomic particles was by "scintillations." Using a microscope, early atomic physicists counted the tiny flashes of light that are made by particles from radium as they hit a fluorescent screen. As soon as Geiger tubes and other radiation detectors were developed, physicists gave up this tedious method. Counting scintillations by eye and microscope was about the most tiresome routine in physics...
...some kinds of radiation, Dr. Collins says, his scintillation counter is at least ten times as sensitive as a conventional Geiger counter. It can also distinguish between different types of particles, which the Geiger counter cannot do without screens or other extra equipment...
...radioactive isotopes and Geiger counters in brain tumor operations has been developed by a group of four Boston scientists including Charles V. Robinson, research associate in Biophysics, and Arthur K. Solomon, assistant professor of Physical Chemistry, both of the Medical School, Massachusetts General Hospital reported yesterday...
...technique consists of using a Geiger counter to locate and outline abnormal tissue in which has been built up a concentration of radioactive phosphorus. A new type of counter the size of a pencil was specially designed for this purpose...
...Place to Hide is, in essence, an excellent list of the places in which Bradley's Geiger counters burst into song. The average Navyman, who thought that the bomb was expected to pulverize its targets, was at first elated by the relatively undamaged condition of many of the ships (some of them could get up steam and float properly). There was less to be elated about three weeks later after Test Baker (the underwater explosion). To old salts, the spectacle of the Radiological Monitors, "decked out in galoshes, gloves, coveralls, and mask . . . creeping along the passages . . . waving a magic...
