DESCRIPTION: The PGM-2L is truly a lightweight portable monitoring system which consists of a moisture resistant BGO* scintillation probe 5/8'' in diameter and up to a 40 foot cable. The readout for this system is a Model PRS-5 Ratemeter/Scaler which includes three single channel switch selectable analyzers. The ten inch long probe contains a sensitive/rugged photo-multiplier, dynode resister string, and a 1/2'' x 2'' BGO scintillation crystal.

APPLICATION: This system is extremely useful for location or movement of underground radioactivity by use of pipes driven into the formation.

SPECIFICATIONS:

READOUT: See PRS-5 Data Sheet
PROBE
