...deal with the wave of future radiation, sanitary engineers should have Geiger counters and know how to use them. They will have to watch carefully all producers and users of radioactive material. They will have to make plumbers wear rubber gloves when cleaning "active" drain traps. They must test rivers, water supplies and sewers to make sure that no radioactivity has slipped...
...concentrating certain elements, including their radioactive isotopes, in their bodies. They are not damaged by them, but the man who eats them may not fare as well. Fish market inspectors of the future may have to deal with shipments of "hot" clams. So far, the AEC has not recommended Geiger counters for the family refrigerator...
...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...
...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...
