Backpack Radioactive Source Search System
Product Overview
The EMMS1000 Backpack Radioactive Source Search System is equipped with a gamma detection module and an optional neutron detection module, integrating functions including alarm discrimination, radioactive source searching, spectrum analysis, and nuclide identification. All functional modules are integrated inside a backpack. Users can perform basic detection and source search via the LED control panel, or connect to intelligent terminals to access advanced functions such as real-time positioning, GIS track mapping, parameter configuration, data storage, data retrieval, and data export.
Features
- Modular Integration: Modular structure allows flexible configuration of gamma/neutron detection modules to meet diverse application requirements.
- Passive Spectrum Stabilization: Automatic spectrum stabilization using natural radionuclides for real-time energy spectrum and radiation level measurement.
- Radiation Heatmap: Automatically generates heat maps based on dose rate measurements during patrol to visualize ambient radiation distribution intuitively.
- Positioning & Track Recording: Integrated GPS positioning automatically records movement tracks throughout field patrols.
- Concise Display Panel: LED control panel displays real-time dose rate, alarm status, and system status in a user-friendly layout.
- Covert Search Mode: Equipped with wired earphones for dose rate audio alerts to enable covert source searching.
- Smart Terminal Connectivity: Bluetooth communication between detector unit and external smart terminal supports parameter setup, patrol survey, data inquiry, and export.
- Power Supply: Battery-powered with low-power design.
