Geiger
Counter name eponym
Geiger appears almost exclusively in Geiger counter, a device that detects ionizing radiation through audible clicks—the faster the clicking, the stronger the radiation.
Named for German physicist Hans Geiger.
The clicking Geiger counter is a stock element in nuclear disaster scenes and uranium prospecting.
