GammaView
Radiation Alert® GammaView: Advanced Gamma Scintillation Survey Meter
The GammaView is a high-performance gamma radiation survey meter engineered for precise, real-time monitoring across laboratory, industrial, and field environments. Built for versatility, it is perfectly suited for both routine safety monitoring and specialized, complex measurement tasks.
Intuitive & Configurable Operation
Designed for immediate situational awareness, the GammaView ensures operators can respond rapidly to changing radiation levels through clear visual and audible feedback.
- User-Friendly Interface: Features a bright backlit digital display, a red LED count indicator, and a distinct audible beep that signals every detected radiation event.
- Customizable Controls: Easily tailor the instrument to meet specific safety protocols or analytical requirements using selectable alarm thresholds and adjustable counting timers.
Single-Channel Analyzer (SCA) Capability
Beyond standard surveying, the GammaView is equipped with powerful Single-Channel Analyzer (SCA) functionality. This advanced feature allows users to set a defined energy “window” within the gamma spectrum to isolate targeted signals.
- Targeted Detection: Focus exclusively on a specific gamma energy range while actively filtering out unwanted signals and interference.
- Noise Reduction: By narrowing the detection window, the SCA significantly lowers background count rates and improves overall measurement selectivity.
- Precise Source Identification: Enhances your ability to confidently identify and monitor specific gamma-emitting sources, even in cluttered or complex radiation environments.
Specifications
| Gamma Scintillation Detector | The GammaView is optimized for the following probes:
1×1 NaI Scintillation Probe: 2.5 cm (1 in.) dia. × 2.5 cm (1 in.) thick with C connector and 3′ MHV-C cable |
