Geiger Counter (Fallout)

Geiger Counter is a Wattz Electronics C-Radz model Geiger Counter. It detects the presence and strength of radiation fields.

Geiger counters make a familiar ticking sound when radiation is detected by it. The more radiation there is the faster and louder the ticking becomes. Useful for walking in areas with high amounts of radiation or swimming/wading irradiated waters which can both be lethal or hazardous to health.

In Fallout 3, the Lone Wanderer has a Geiger Counter built into his PipBoy 3000.
