APPLICATIONS

Alpha disk sources are designed for use in various industries including, but not limited to:

• Laboratories: They are ideal for performing functional checks on gamma counters or spectrometers.
• Radiation Protection: Alpha disk sources can be used for functional checks and periodic verifications of radiation protection probes and systems.
• Training and Education: Alpha disk sources can be used to illustrate fundamental concepts in nuclear physics and radiation science. Students can observe and study radioactive decay, half-life, energy spectra, and interactions of radiation with matter.
• Security: Alpha disk sources are also useful for functional checks and periodic verifications of portable devices used to identify radiological threats and for conducting emergency exercises.

AVAILABLE SIZES

Each alpha disk source is manufactured by chemically plating radioactive material on to the surface of a silver disk that is mounted in the bottom of a Plexiglas® disk. The sources are unsealed and are available in two diameters:

• 0.125 x 1.0 inches (3.2 x 25.4 mm)
• 0.125 x 2.0 inches (3.2 x 50.8 mm)

The source material deposit will be the same for each size, 2-3 mm in diameter located on the silver disk located in the center of the disk.

CALIBRATION OPTIONS

Alpha disk sources are not available for calibration. The maximum deviation of the delivered activity from the nominal values listed is ±20%.

REGULATORY COMPLIANCE

Activities provided will not exceed the U.S. NRC Exempt Quantity limit.
