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, Cm-244, Pu-238, Pu-239, U-233
- Mix – 0.022 uCi (Pu-239, Am-241, Cm-244)
