Abstract
This report describes an efficient, easy to use, and inexpensive metho d for detection of alpha-activity in biological samples, the alpha rad iometer. The actinide elements are coprecipitated from acid-dissolved, ashed samples with bismuth phosphate and the precipitate is then mixe d with ZnS(Ag) scintillation powder. The mixture is dried, in a thin l ayer, on the surface of a polystyrene cuvet and scintillations from th e layer are detected with a photomultiplier tube. An optimal counting efficiency is obtained with a scintillation powder thickness between 2 5 and 40 mg.cm(-2).
