title: A new container geometry for better sensitivity in radiometric measurements.
abstract: A new two-compartment liquid scintillation vial system for radiometric measurement has been evolved, such that the light attenuation by the inner vial is minimized. The increase in relative efficiency is over 70% better than in an earlier design. The system is compact and versatile, and is suitable for automated, cumulative, or continuous radiometric measurements.
