GMP-N7
GMP-N7
GMP-N7 Portable spectrometric gamma imaging system
The GMP-N7 combines several functions in one device. It can localize hotspots from a distance, identify the corresponding radionuclides and estimate the dose-rate contribution of every hotspot seperately. The GMP-N7 is based on a CZT-detector. Its unique design allwos both coded mask AND Compton imaging. This combination provides a full 360° FOV (Compton) while having a great 3.5° resolution (coded mask). The high processing speed allows to perform real-time imaging and tracking mobile sources.
Benefits
- Real-time imaging
- High resolution (coded mask) and360° field of view (compton)
- Wide energy range forspectrometry from 50—3000 keV:Radioisotopes from 241 Am to 60 Co
- H*(10) dose rate estimation perhotspot
- Dose rate in specified distance tosource can be calculated
- No cable needed, fullyindependent and autonomous
- User-friendly, portable device
