Why do Geiger counters click?
Every time a radioactive atom breaks down, knocking off nearby electrons, this builds up enough charge to create a pulse and therefore a “click” on the detector. Each click indicates a single atom has decayed, and so more clicking means more atoms and therefore, more radiation.
How expensive is a Geiger counter?
Apparently there are over 10,000 users, though the viewing of maps is limited to Radiation Watch members. The main advantage of the Pocket Geiger appears to be cost.

What is a normal geiger counter reading?
Depending on the type of Geiger counter used and the elevation, the average natural background radiation level ranges between five and 60 counts per minute or more.
What are some good forms of radiation?
Some examples of radiation include sunlight, radio waves, x-rays, heat, alpha, beta, gamma ionizing radiation, and infrared, just to name a few. Not all of these types of radiation are harmful, in fact, in moderation, most radiation will not pose a health risk.
