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

Sources from fromer Analytics 

• Planchet
• Rings
• Rectangular

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 alpha and beta sources. The surface emission rate in 2π is given on the certificate and is NIST traceable for most nuclides. All electroplated sources are prepared +/- 30% of nominal activity.

Series includes 

EAB – unmounted
EAB-PL simulate planchet samples
EAB-LB for low level counting
EAB-PL-FP simulate smear test
EAB-LB-FP simulte smear test
LDS – large area standards for i.g. alpha and beta probes
