词汇 | geiger counter |
词源 | Geiger counter. The Geiger counter is sometimes called the Geiger-Muller counter, for both German physicist Hans Geiger (1882–1945) and the scientist who helped him improve upon it in 1927. Actually it might better be named the Geiger-Rutherford- Muller counter, because the New Zealand–born British physicist Ernest Rutherford had invented the device, with Geiger, 15 years earlier. The clicking electronic counter, which measures nuclear radiation, is owned by many hopeful prospectors today and widely used as a safety device; it is also employed in medi- cine to locate malignancies. Geiger designed other types of counters as well. |
