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. SPECIFICATIONS: Meter: Rugged, recessed 2-1/2" meter. Range Switch Positions: Off; Battery Test; X1; X10; X100; X1,000. Detector Switch (Toggle): Internal (pancake), External (4 Additional Probes). Time Constant Switch: Fast, Slow (approx. 2 & 11 sec.). Figure 1: TBM-6SPE Ranges: 4 linear for each detector: 0-500; 5,000; 50,000; 500,000 cpm for external and 0-0.15; 1.5; 15; 150 mR/hr. for internal detector. Optional: Addition scales and overlays available: Sieverts, etc. Internal Detector: T-1190 2" O.D. Beta Pancake Geiger for internal. Internal Detector Efficiency: BETA Pancake $^{14}$C 40% Exclusive of any geometry factor. $^{32}$P 98% Exclusive of any geometry factor.

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 2" 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/cm$^{\textrm{2}}$/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. Calibration: Single master Cal Pot for each detector, plus individual Cal Pot for each scale. Pots adjust from outside case. Power: 9V Transistor battery (Eveready E1220 or equivalent). Battery life - 100 hrs. normal operation. Dimensions of Meter: 3" Wide x 5-1/4" Long x 2-1/4" Deep. (7.6 cm x 13.3 cm x 6cm). Total Weight: 15 lbs. Shipping Weight: 30 lbs. $^{\mathbf{1}}$Excluding Geometry.
