Description
Engineered for High Gamma Flux Environments
The High Dose Gamma Bare Geiger-Muller Tubes from Exosens are designed to provide reliable and accurate detection in environments with high radiation levels. By reducing the gas volume and using optimized halogen-quenched mixtures, these tubes prevent signal overload while maintaining precise detection capabilities. This ensures consistent performance even under extremely high gamma flux conditions.
Fast, Stable, and Reliable
These Geiger-Muller tubes offer fast response times with low dead time ranging from 9 µs to 15 µs. Their plateau slope is tightly controlled for stable measurements across a wide dose rate range, from as low as 3 × 10−3 mGy/h to 10,000 mGy/h, depending on the model. This makes them compatible with high-dose radiation monitors, survey meters, and integrated safety systems.
Versatile Applications
Available in multiple types, including ZP1300, ZP1310, and ZP1320, the tubes provide tailored sensitivity for varying gamma flux levels. They are widely used in nuclear research reactors, nuclear power plants, advanced SMRs, industrial monitoring, defense surveillance, and portable radiation detection systems. Their durable design ensures long-term performance even in demanding conditions.
Precision Detection for Critical Operations
The high dose gamma tubes are engineered to handle challenging environments where standard Geiger-Muller tubes might fail due to overload. By combining reduced sensitivity with a robust halogen-quenched design, they deliver precise and reliable radiation detection. This makes them an essential tool for professionals in nuclear, defense, and industrial sectors who need dependable monitoring under extreme conditions.
