Betasäteilylähteet
Beta emitting nuclides with certificate containing both activity and 2π emission rate. Sources are traceable to NIST, other certificates on request. Source configurations are surface conductive on all surfaces to enable their use in windowless proportional counters.
Area sources are also available as beta standards, but not here, you find them to the left.
Beta Particle Standard - Type MF2 "Scatterless"
This is a “scatterless” configuration in which the activity is applied as a 3 mm spot centered between two laminated 0.9 mg/cm² aluminized Mylar...
Beta Particle Standard - Type A
Beta Particle Standards—Type AThe active material is uniformly distributed over the surface of a 0.937” (23.8 mm) diameter foil and sealed in an...
