FIDLER Probe
The FIDLER Probe features a large NaI(Tl) scintillation crystal measuring 127 mm diameter × 1.66 mm thick with beryllium radiation entrance window 127 mm diameter × 0.254 mm. Total dimensions span 11.6″ × 7.6″ × 17.2–26.7″ with adjustable handle telescoping from 44–68 cm, weighing 7.9 lb (3.60 kg) in anodized aluminum housing. Count rate range reaches 0–1.5 Mcpm with dose rate units displayed in cpm and cps. Maximum photomultiplier tube voltage operates at +1600V with internal voltage divider wiring.
This probe simultaneously monitors four energy windows via multichannel discriminator: Window 1 detects 13–18 keV low-energy x-rays, Window 2 identifies 59–60 keV Am-241 isotope signatures, Window 3 tracks 143–220 keV U-235 radiation, and Window 4 spans complete 13–220 keV gamma range. The Base Unit display simultaneously records all four channels but selects any two for operator viewing. Onboard microprocessor creates independent high voltage without cable transfer. Adjustable alarms with memory storage trigger on programmed energy channel thresholds. The probe operates between -22°F to 122°F with IP67 immersion protection to 1 meter depth for 30 minutes.
Radiological safety specialists deploy the FIDLER Probe for weapons of mass destruction material detection and identification. Intelligence agencies conduct multi-spectral analysis of unknown radiation sources to classify threat materials. Environmental remediation teams survey contaminated sites where uranium or americium residues require measurement. Border security personnel screen cargo containers for shielded radioactive contraband using energy window discrimination.
Tactical Supply Pakistan provides specialized low-energy radiation detection enabling isotope identification through this four-channel spectroscopic probe system. Organizations gain advanced threat assessment capability with military-rugged construction meeting ANSI N42.34 standards.
Can the FIDLER Probe distinguish between different radioactive isotopes?
Yes, the four simultaneous energy windows enable operators to identify specific isotope signatures by comparing activity levels across characteristic energy bands associated with common threat materials and industrial radioisotopes.
