— A Geiger counter — named after Hans Geiger, a German scientist from the early 1900s who worked on detecting radiation — is an instrument that can detect radiation. Geiger counters can tell you there is radiation around you, but it can't tell you the original source of the radiation, what type it is or how much energy it contains.

This expression is adequate when the sample counting rates is much higher then the background counting rate. However, when the background counting rate is appreciable compared to the sample counting rate the net counting rate, R, and its Standard Deviation, σ r, are determined by σ R = [σ Rg 2 + σ Rg 2] ½ = [g g t R + b b t R] ½ (8) where

— The number of clicks you hear gives a rough indication of how much radiation is present (the meter gives you a much more accurate idea). Before the counter can detect any more radiation, it needs to be restored to its original state through a process called quenching, which cancels out the effects of the Geiger discharge.
