Nuclear and Radiation Monitoring
ATLIS offers a comprehensive portfolio of early-waning radiation monitoring solutions based on diverse detection technologies: Geiger-Müller gamma probes, ionization chambers and gamma spectrometry systems.
Spectrometric gamma monitoring systems
ATLIS offers a wide portfolio of custom-made solutions for spectrometric gamma dose rate monitoring, based on advanced detection technology employing scintillating crystals (NaI(Tl), CsI(Tl), CeBr3, and more) with PMT or SiPM-based readout electronics.
Our spectroscopy amplifier/multi-channel analyser board allows recording of energy spectra up to 8k channels, with rates up to 200 kcps, along with real time ROI analysis. Optional GMT probes can be added.
te [°C] – onboard temperature sensor of the GMT-MPC controller
hv [V] – onboard high voltage monitor ADC
c0 [cps] – count rate of GMT sensor low-range channel with ~ 1.50 cps*h*Sv-1 sensitivity
c1 [cps] – count rate of GMT sensor high-range channel with ~ 0.05 cps*h*Sv-1 sensitivity
Data from GMT-2 dual-range system used for environmental dose rate monitoring.
Data from Low-range GMT-2B detector under exposure to a Cs-137 source using ATLIS dead-time free time-to-first-count detector controller, for extended dynamic range and improved linearity.
Gamma dose rate systems
ATLIS GMT-2 is a dual-range Geiger-Müller environmental dose rate probe with integrated rate-meter, microprocessor control and USB/RS232/485 interface. The probe is based on two Geiger-Muller detectors (low and high range), guaranteeing a default operating range from 10 nSV/h to 10 Sv/h. Customised range and probes are also available.
Key features:
- Dual-range GM tube readout (customisable measuring range)
- Integrated microprocessor-controlled rate-meter and control electronics
- Interface: USB(VCP)/RS232/485
- High-stability, low-ripple and low-power adjustable high voltage supply
- Integrated HV monitor for power-good indication
- Time-to-first count controller for dead-time-free detector operation, yielding extended dynamic range and linearity, along with enhanced GMT life
- Low current consumption
- On board WDT, diagnostics and temperature sensor
- Open-source Python API for instrument control
- IP66 or IP67 housing
Configurations, add-ons and expansion modules:
- Telemetry/Radio modules: GPRS/LoRa/WiFi
- Ethernet interface with PoE (Power-over-Ethernet)
- Integrated datalogger
- Rechargeable battery system with optional solar-panel unit
- Human-interface module with display and calibration tools
