RadiationUltra Sensitive Giant Geiger Counter KitAlpha, Beta & Gamma Sensitive Miniature Geiger Counter KitDemonstration VideoAvailable on our WebsiteOur largest and most sensitive geiger counter kit uses aRussian Geiger Mueller tube. This tube is 0.75” in diameterx 7.2” long and because of its large surface area it is sosenstive to beta and gamma rays that the background counthere in Arizona on this kit is about 100 counts per minute.Operates on one 9V battery (not included). Flashesa bright red LED and “clicks” from a small onboard speaker with each particle detection. Sizeof PC board is 7-13/16” x 1-7/16”. Complete withall parts, GM tube, and instructions. Requiressoldering. No case available.Ultra Sensitive Giant Geiger Counter Kit............C7026 $149.00Miniature Geiger Counter Kit measures alpha, beta, and gammarays using a mica window GM tube type 6108. The miniaturemica window tube is only 1.6” long x 0.35” diameter. The tubewas made for the US Navy during the Cold War and is precisionmade. This kit has its sensitive detection window at the end of thetube at about 0.3” diameter so you that you can pinpoint specificsources of radioactivity. This kit uses a 555 IC, a small metalspeaker, and a blue-green LED to provide indication of radiationwith both clicks and flashes of bright light each time radioactiverays strike the mica window. Comes with all parts, PC board, andinstructions. Operates from one 9V battery (not included). Thiskit requires soldering. Skill level 2. Please do not purchase thiskit if you have never soldered an electronic kit before.Replacement Geiger Mueller Tube C7291 $80.00optional plastic Type 2 box C6364 $2.40Alpha, Beta & Gamma Sensitive Miniature Geiger Counter Kit............C6998 $149.95Highly Sensitive Beta Gamma Geiger Counter KitVery sensitive geiger counter kit uses a russian geiger tube which is even moresensitive than the tube used in our C6979 kit. This kit can detect radiationfrom contamination, old radium watch hands, certain orange colored plates,lantern mantles, radioactive minerals and even radioactive vaseline glassmarbles. Produces familiar clicking sound and lights up a bright red LED witheach click. Detects background radiation from cosmic rays (here in Scottsdale,Arizona the count is about 14 per minute). When we placed a vaseline glassmarble next to the tube, the count went to about 50 per minute. Operatesfrom one 9V battery (not included). Complete with all parts, PC board, andtube. As a bonus we will include a vaseline glass marble. PC board size is2.5” x 1.5”.
