Model # PGM-2L
- SMALL DIAMETER
- HIGH SENSITIVITY
- MOISTURE RESISTANT
- OPTIONALLY SUBMERSIBLE
Figure 1: PGM-2L
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.
- READOUT: See PRS-5 Data Sheet
- Length: 10''
- Weight: 10 oz.
- Diameter: 5/8''
- Scintillator Type: BGO*
- Scintillator Size: 1/2'' x 2''
- Drive Capability: 40' into PRS-5 Readout Package
- Sensitivity: Typically 350,000 cpm/mR/hr
- Efficiency: Better than 50% for Cs137 gammas
- *High Density: 7.13 (vs. 3.67 for Nal)
nearly doubles sensitivity for gammas in general. High atomic # enhances
sensitivity to low energy gammas by a further factor of up to 10.
- **Options: Immersion proof
