Description
Optimized for Low Radiation Environments
The Low Dose Gamma Bare Geiger-Muller Tubes from Exosens are engineered for highly sensitive detection in environments with low gamma radiation levels. With increased gas volume and a carefully balanced mixture, these tubes provide accurate and stable measurements, even in situations where conventional Geiger-Muller tubes might miss low-level signals.
Fast and Accurate Detection
Designed for rapid response, these tubes feature low dead times (100–210 µs) that allow real-time monitoring of radiation levels. The plateau slope is precisely controlled to maintain signal stability over a broad range of low-dose rates. This makes them perfect for applications that require sensitive, continuous, and accurate radiation detection.
Versatile Applications
The tubes are available in types ZP1210 and ZP1220 (/01), tailored to various low-dose detection needs. They are widely used in nuclear fuel cycle plants, nuclear research reactors, small modular reactors (SMRs), advanced nuclear facilities, and portable radiation monitoring equipment. Additionally, their robust construction makes them suitable for defense, border surveillance, and industrial control environments.
Precision and Reliability for Critical Operations
By combining enhanced sensitivity with a durable halogen-quenched design, these low dose gamma tubes provide dependable performance for professionals who need accurate monitoring in delicate radiation environments. They are an essential component for high-precision systems that demand reliability, low maintenance, and long-term operational stability.
