Rankin, M O; Spear, W G

BS>A scintillation alpha-beta-gamma filter counter has been developed which simultaneously monitors filters for alpha ajn beta-gamma contamination with none of the faults of the present equipment. The instrument has two lucite light pipes, two RCA 6655 photomultiplier tubes, two scalnag units, and a light-tight box with a roller bearing mounted slide for transporting the filter. The average center geometry for the alpha probe is 20 to 25 per cent wlth a background of approximately 2 c/m. The average center efficiency for the beta-gamma probe is 0.8 to 1.0 per cent for a 600-kev gamma source and 20 to 25 per cent for a 500- kev beta source. (auth)
