Whats the life expectancy of Geiger Counters, do they wear out?
Most of the components in a geiger counter are fairly ordinary electronic devices, the sort of bits and pieces you find inside radios, personal stereos and other electronic gadgets and these have a life expectancy of several decades. The only unusual component is the Geiger Muller radiation detector and these can be expected to work reliably for at least 50 years, probably longer.
