Abstract
An automatic scintillation counter for the measurement of low beta activity samples is described. Background is in the order of one (1) count per minute. Efficiency of counting for K-40 betas is thirty (30) per cent. The scintillator is a thin plastic phosphor mounted on the sample which makes a simple, rugged package suitable for automatic sample changing. Photomultiplier tube noise measurements, preamplifier circuit, and the mechanical details are discussed.
