A small-volume and low-background digital anticoincidence beta counting system for C-14 dating using a gas counter combined with tiled CdTe wall detectors

A low-background anticoincidence beta counting system was developed by combining an internal gas proportional counter with CdTe detectors to decrease the volume of the anticoincidence gas counter. According to performances of CdTe detectors, digital signal processing was incorporated and a small-volume and low-background digital anticoincidence beta counting system was developed for C-14 dating.
