ASSEMBLED! Sensitive Geiger Counter - Battery Included
ASSEMBLED (no soldering required) - 9V BATTERY Included!
Sensitive geiger counter uses a Russian geiger mueller tube and is sensitive to Beta and Gamma rays. Want to know if that orange colored plate that was all the rage in the 60's is radioactive, how about your dad's radium dial watch, or the mantles on your camping lantern -this will tell you! Produces the familiar audio clicks and lights up a blue/green LED in response to radioactive sources. Random clicks are even heard from your the counter as cosmic rays strike the tube! Uses a Russian GM tube that was made during the cold war (we test every one for proper operation), various resistors, capacitors, and a special miniature speaker. Operates from one 9V battery INCLUDED. Comes completely assembled- no soldering required (no case available). Size of PC board 4-5/16" x 1-1/2".
