Energy Dependent Efficiency in Low Background Alpha Measurements and Impacts on Accurate Alpha Characterization
Abstract
A difference in low emissivity alpha particle measurements for the same samples was observed between an Alpha Sciences model 1950 gas proportional counter and the XIA UltraLo-1800 ionization chamber. The energy dependent efficiency was evaluated for each instrument to reconcile the difference, and the implication of instrument design bias on measurement results is presented.
