Abstract
This work describes an updated version of a beta spectrometer that mea sures pure beta emitter activities. The detection system consists of a plastic scintillator surrounded in a 4pi geometry by large anticoinci dence NaI(Tl) scintillators. A thin silicon detector, inserted between the plastic and the sample, helps to reduce the gamma background. A M onte Carlo code, used to calculate the quite complex spectrometer resp onse function to any isotope, is also described.
