The overwhelming loss in counting efficiency occurs during the scintillation process itself . 絕大多數(shù)計(jì)數(shù)效率的損失出現(xiàn)在閃爍過程本身。
百科解釋
The counting efficiency is the ratio between the number of particles or photons counted with a radiation counter and the number of particles or photons of the same type and energy emitted by the radiation source (IUPAC Compendium of Chemical Terminology 2nd Edition, 1997). Counting efficiency varies for different isotopes, sample compositions and scintillation counters.
