tbm-6spe

FIRST RESPONDERS RADIATION DETECTION EMERGENCY KIT

Model # TBM-6SPE

FEATURES:

FIVE SEPARATE DETECTORS

DETECTS ALPHA, BETA, GAMMA, X-RAYS, & NEUTRONS

EASY SWITCH TO CHANGE FROM INTERNAL TO EXTERNAL PROBES

LIGHTWEIGHT - FITS INTO A BRIEFCASE

DESCRIPTION: The TBM-6SPE features an internally mounted 2 inch Beta pancake GM detector (T-1190) with window looking downward from bottom of case and four external probes for detection of Alpha (PAS-8), low energy Gamma (PGS-3T), all Neutrons (PNS-20T), plus the Gamma Search Probe (PGS-3L). A sliding shield protects pancake detector when not in use. This system is half the weight of other systems.

External Detector Description:

PAS-8: Alpha Scintillation Probe with 1" diameter x 0.8 mg/cm squared window. For use wherever a high efficiency, low background Alpha detector is indicated.
PGS-3T: Low Energy Gamma Scintillation Probe, 1" diameter x 1mm NaI(Tl) crystal protected by a 5 mil. aluminum window, sees X-rays and Gammas > 10KeV and Betas > 100KeV.
PGS-3L: Gamma Scintillation Search Probe utilizing a highly gamma sensitive crystal (NaI(Tl)). 2'' diameter x 1'' long hermetically sealed crystal optically coupled to photomultiplier tube. Gamma sensitivity is 100 times greater than GM tubes Will also detect X-rays > 25KeV. Sensitivity of the PGS-3L is in the order of 1,000,000 cpm per mR/hr.
PNS-20T: Fast & Slow Neutron Scintillation Probe. The n-p reaction is used to measure energy deposited by Fast Neutrons. Thermal Neutrons are detected by means of the Boron n-Alpha reaction. Probe delivers approximately 20 cpm per neutron/cm²/second and requires a 900 volt supply. The probe is 8" long x 1.5" in diameter. It is completely insensitive to Gammas in fields below 10 R/hr.
T-1190: Internal Pancake GM detector
