why do Geiger counters make that strange noise and why is it so different to other sensors that just beep?
In: Technology
In the detector, the tube, there is a metal rod and an inert gas like neon. When ionizing radiation enters the tube those particles push the particles around in the tube and when there is enough it creates electricity in the tube which the rod absorbs and the current it sent to the speaker. The current causes the speaker components to jerk and that causes the popping noise we here.
