Colossal 4″x4″x16″ NaI(Tl) Detectors: Armored for Extreme Environments
When radiation monitoring moves into harsh, unforgiving environments, standard aluminum enclosures simply fall short. ATR Crystal engineers this colossal 4″x4″x16″ NaI(Tl) scintillator specifically to deliver maximum gamma-ray stopping power under extreme conditions. Armored entirely in heavy-duty stainless steel, this massive detector is the ultimate solution for rigorous border security portals, maritime scanning, and rugged industrial arrays.
- Extreme Durability: Hermetically sealed within a premium stainless steel housing, providing superior corrosion resistance and uncompromising mechanical protection.
- Massive Stopping Power: The colossal 4x4x16-inch geometry is flawlessly coupled with a larger 3.5-inch PMT, maintaining a highly reliable energy resolution of ≤8.5% @ 662keV.
- Instant Deployment: Outfitted with the universal 14-pin connector, engineered for immediate and seamless integration into standard digital MCAs and Gamma-ray detection systems.
