This tiny fully assembled Geiger counter is only 1.89" long x 0.86" wide x 0.46" thick. This Geiger counter detects beta and gamma rays and emits clicks and bright orange flashes of light. Operates from one 9V battery (not included). Here in Arizona, this Geiger counter emits about 2 to 4 clicks per minute from background radiation. Use this to detect radioactive minerals, old radium watch hands, radioactive fiesta ware orange plates, lantern mantles, etc.
