Alpha Spectroscopy System

Alpha spectroscopy is a technique widely used in the following applications

  • the radiochemical analysis
  • the assessment of environmental studies
  • environmental radioactivity monitoring
  • health physics personal monitoring
  • assessment of nuclear installations, the determination of location and the study of its effect on the environment
  • geological dating and mineralogy
  • educational research applications

Alpha spectroscopy systems are used for measuring low activity samples that decay by Alpha-particle emission.

Alpha spectroscopy system model 1000 is used in educational research applications due to following features:

  • Selection of different energy range
  • Selection of different distances between source and detector
  • Selection of various PIPS and SSB semiconductor detectors with different dimensions


vacuum chamber

The vacuum chamber of this system is designed and fabricated for following applications:

  • Possibility of rapid decontamination
  • Possibility of rapid sample replacement
  • Possibility of replacement and use PIPS and SSB semiconductor detectors
  • Possibility to use charge-sensitive preamplifier types
  • Possibility of change or correct for measuring various parameters, such as the stopping power in gas
  • Improvement of absolute activity measurement based on the coincidence of α-x, α-γ and β-γ
  • Ability to maintain vacuum continuously and accurately

Because of the possibility of using PIPS and SSB semiconductor detectors with different thicknesses, this system in addition to the alpha particle spectrophotometry has the capability of measuring the maximum beta particles energy and determining the energy of conversion electrons for educational research purpose.
