摘要：

New commercial liquid scintillation counters allow rapid alpha/beta measurements. Associated with liquid-liquid extraction techniques, rapid and selective actinide analyses are possible. Uranium, thorium and americium extractions with tri-n-octylphosphine oxide (TOPO) in toluene have been investigated. Detection limits of 40 mBq.1(-1) for alpha-emitter; are currently obtained with a Packard 2550 TR/AB(TM) liquid scintillation analyzer.
