GM Counter


In the field of nuclear research and applications of radio isotopes, the Geiger Muller Counters play an important role. The GM Counters are used to detect Alpha, Beta, Low energy X and Gamma radiation. 
AET's Geiger Counter GM-11 provides a Built-in programmable timer/counter and 16x2 alphanumeric display to show time and count values.

  • Determination of the Plateau of the GM counter and its percentage slope.
  • Determination of dead time of Geiger counter for Beta and Gamma radiation separately.
  • Determination of back scattering coefficient of a material for beta radiation.
  • Determination of back scattering coefficients of a material for beta radiation.
  • Determination of self absorption coefficient of beta source.
  • Verification of inverse square law for gamma radiation.
  • Determination of half life of a radioactive source.
  • Determination of mass absorption coefficients of aluminium for gamma and beta radiations.
  • Determination of end point energy of beta radiation by finding out its range in aluminium. 
  • Built-in Regulated power supply for exciting GM Detector.
  • Keypad is provided for setting time. control/count control operations.
  • 16x2 Alphanumeric LCD with backlight to display time and count.
  • PC Interface is provided to view the data on the PCSoftLab1.0 (optional).
  • Detailed experimental manual to perform various experiments. 
  • Regulated, variable EHT.
  • Selection of preset time or preset counts.
  • Radiation dosimeter
  • The Geiger Counting System is used to a large extent in research and academic fields.
  • Ideally suited for general purpose low energy beta counting.
  • Widely used for labeled sample counting.
  • A must in radio tracer techniques used in biochemistry,  Genetics,  Medicine, etc.
  • To impart training in Nuclear Physics and Agricultural Physics.
