title: Spiral Capillary Plastic Scintillation Flow Counter for Beta Assay.
abstract: Tracer counting of beta emitters in aqueous solution was performed with a detector fabricated from a plastic scintillator capillary. The detector exhibits low gamma background and reproducible detection efficiency, and it requires minimum sample preparation. Counting efficiencies were determined for aqueous solutions of P(32), Na(22), and C(14) and for C(14)O(2) gas.
