Abstract
From the practicable viewpoint for environmental radioactivity measure ment and monitoring, the liquid scintillation radioassay has been appl ied to low-level pure-beta and gamma-emitter mixtures by using the mos t probable value theory. In low activity measurement, it is required t o select a suitable emulsion scintillator and to deal with the calcula ted data statistically. Detection limit for a solution sample has been roughly estimated to be 10(-2) Bq ml(-1).
