Alpha Standards

Alpha and alpha spectrometry sources are intended for calibrating and checking solid state alphaspectrometers, for applications in environmental monitoring and research.

Wide area Sources are intended for calibration of probes and instruments and low level counters

 

Alpha Spectroscopy Sources type A-1

Alpha Particle Standards—Type A-1 The type A-1 source is permanently fixed in an aluminum holder 1” diameter x 0.125” high (25.4 mm x 3.18 mm). The active diameter is 0.197” (5.0 mm). All alpha...

Alpha Spectroscopy Sources Type A-2

Alpha Particle Standards—Type A-2 The type A-2 source is permanently fixed in an aluminum holder 0.5” diameter x 0.250” high (12.7 mm x 6.35 mm). The active diameter is 0.197” (5.0 mm). All alpha standards...

Alpha Spectroscopy Source Type PM

Alpha Particle Standards—Type PM The PM source is mounted in a plastic holder from which it can be separated for installation in a counting chamber or device. The holder is 25.4 mm x 3.18...

Alpha Source Set

The composite alpha source is designed to be used as an energy marker for alpha spectroscopy systems. Pu-239, Am-241 and Cm-244, with 370 Bq each, are electroplated onto a polished platinum or platinum clad nickel...

Alpha Spectroscopy Sources - Isotrak

The Isotrak alpha standards are manufactured to a tolerance of +/-30% of the nominal activity. Calibrated single nuclide sources are supplied with a DAkkS certificate stating alpha particle emission rate and activity. Possible nuclides Np-237 Pu-239 Am-241 Pu-238 Cm-244

Alpha sources for research - AFR

The AFR source standard mounting is in a type A-2 capsule with a 9.5 mm active diameter. The active element for Am-241 consists of a rolled monolithic foil in which theactivity is incorporated...

Wide area sources - Planchet, Ring and Rectangular sources Isotrak (EU)

The wide area standards are designed for the calibration wide area counters and low level counters. Each source come with a certificate stateing the emission, activity, traceabillity and uncertainty. The Isotrak sources from Nuclitec...

Wide area sources - Planchet, Ring and Rectangular source from Analytics (US)

These standards are used for the calibration of alpha, beta and wide area counters. All sources are NIST traceable based on output or contained activity. NIST certification on contained activity is not available on some...
