Function and Applications

The Geiger-Mueller Counter tube, 45 mm  is a self-extinguishing halogen counting tube for the detection of alpha, beta and gamma radiation. A long plateau (approx. 425 V…650 V) with only a slight slope renders the selection of the operating point uncritical. The actual counting tube, which is mounted in a metal cylinder with BNC socket, has a thinwalled metal sheath that is permeable to alpha radiation. 


  • Highly sensitive counting tube
  • Useful to investigate weakly radioactive sources
  • Even natural radioactive sources can be investigated
