Alpha Calibration Sources

Alpha Calibration Sources

  • Alpha point sources (EAS) are in the form of a stainless steel disk, unmounted (Type C or D) or sealed on an aluminum ring (Type A or B), at the center of which the radionuclides are electroplated.
  • Radiological characteristics of the sources are measured with a calibrated grid cell detector.
  • Alpha Sources are available in 0.008 uCi and 0.08 uCi Am-241 or Cm-244.
