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.
Beta Calibration Sources

Beta Calibration Sources

  • Radionuclides are deposited between two hot-sealed polyester foils (approximately 75μm thick each). Each face of the source is gold vacuum-coated for optimum measurement efficiency. They are then mounted in a steel ring.
  • Radiological characteristics of the sources are measured with a calibrated gas flow proportional counter.
  • Available in 0.002 uCi and 0.08 uCi
  • Available in the following Radionuclides: Cl-36, Co-60, Cs-134, Cs-137, Na-22, Pm-147, Sr-89, Sr-90, Tl-204

Kits Available

EBS A and EBS B sources are also available in kit form. Radionuclides supplied are Pm-147, Cs-134, Cs-137, Sr90 + Y-90, Tl-204 and Na-22 with an activity of 0.002 μCi (80 Bq) or 0.08 μCi (3 000 Bq). Other activities of EBS sources are available on request.
