Extension of the SIR to beta emitters using liquid scintillation (ESWG(II))

Remit:

The objective of the ESWG(II) is to develop and implement a self-consistent scheme for the inclusion of alpha and beta emitters within the Système International de Référence (SIR), currently restricted to gamma emitters, providing:

  • Support and guidance to the BIPM in defining the most adequate technical procedures for ongoing comparison of beta and alpha emitters;
  • Advice on the best experimental setup for implementing the extension of the SIR at the BIPM;
  • Documentation of the specific metrological principles as well as the practical aspects of the operation of the extended SIR at the BIPM.

Chairperson:
