Geiger-Mueller Counter tube, 45 mm
Article No: 09007-01
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 Extinguishing material halogen self-extinguishing halogen counting tube with BNC-plug including grid to protect the counting tube Sheath: 2 ... 3 mg/cm2 Operating voltage: 500 V Length of plateau: 200 V Slope of plateau: 0,04 %/V Dead time approx.: ca. 100 µs Background effect approx.: ca. 45 pulses/min Diameter of housing: 60 mm (Ring for support rod: 75 mm) Diameter of counting tube: 45 mm Length: 80 mm Mass: 320 g Screened cable, BNC, l = 750 mm (included, art. no. 07542-11) Support rod to fix the device is included (with thread, screwable)
