Abstract :
Appropriate optical and electronic components used in conjunction with an improved scintillator solution allow alpha liquid scintillation spectroscopy with an energy resolution of 200 to 300 keV and a background of 0.01 to 0.005 cpm. Liquid-liquid extraction procedures allow selective extraction of nuclides of interest directly into the scintillator. Applications to environmental samples are illustrated.
