This Working Group is devoted to the development of the metrological aspects of beta-particle spectrometry and its applications. This includes, but is not restricted to:

Theory

Beta (β±) and electron capture (ε) transitions
Theoretical shape factors and influence of the nuclear current
Atomic effects

Experiments

Instrumentations used for beta spectrometry
Techniques that need beta information
Confidence on experimental shape factors
Data analysis and unfolding methods

Simulations

Confidence on the physical processes: low energies, radioactive decays, atomic rearrangements
Comparison of the results of different software: Geant4, Penelope, etc.

Evaluations and dissemination

Confidence and uncertainties on experimental shape factors
Evaluation procedure for establishing recommended experimental shape factors
Mean energies, log ft values, database
