Process and apparatus for converting liquid beta radiation scintillation counter to gamma radiation counter

摘要

A process and apparatus are disclosed for converting a conventional beta radiation liquid scintillation counter to detect gamma radiation. Special mini-size counting vials are employed of the same size as those used in the detection of beta radiation but such vials detect gamma radiation, which is measured by the beta radiation liquid scintillation counter. These mini-size counting vials have relatively thin walls formed from scintillation crystal chips of an alkali metal halide and are preferably covered by and embedded in a polynuclear aromatic compound.
