Model 44-213 FIDLER Low-Energy Gamma Detector

The Model 44-213 FIDLER (Field Instrument for Detection of Low Energy Radiation) is a specialized, hand-held gamma spectrometer designed to detect and measure low-energy gamma emitters, particularly Plutonium-239 and Americium-241. It uses a thin, large-area scintillation detector (often sodium iodide) optimized for the low-energy photons (20-200 keV) these materials emit. This instrument is critical for nuclear safeguards, border security (to detect smuggled nuclear materials), environmental monitoring around nuclear facilities, and emergency response to radiological incidents involving transuranic elements.

• Hand-held gamma spectrometer optimized for low-energy photons (20-200 keV).

• Specifically designed to detect isotopes like Plutonium-239 and Americium-241.

• Used in nuclear non-proliferation, border security, and environmental remediation.

• Provides isotopic identification, not just gross count rates.

• A key tool for the International Atomic Energy Agency (IAEA) and national safeguard agencies.

• The “FIDLER” is an iconic instrument in the field of nuclear material detection.

Find hidden nuclear materials. The Model 44-213 FIDLER is the definitive field instrument for detecting low-energy gamma emitters like Plutonium.
