Gamma Spectrometry System

Gamma detection and spectroscopy module for application on drones

This is state-off-the-art technology for light airborne monitoring taking advantage of drone devices as carriers. The system offers an excellent environmental radiation monitoring performance. It is designed for surveying smaller areas to search for uncontrolled radioactive sources, potential contamination or work in places with  hazardous dose level.

This module consists of an NaI(Tl) gamma spectroscopy probe, a high dose level detector equipped with two energy compensated GM tubes and a mini air sampler for air contamination measurement. The gamma spectroscopy unit works with spectra with resolution from 256 up to 2048 channels and energy range from 50kev to 03Mev. Typically the module is designed to incorporate NaI(Tl) detectors with dimensions of 2×2 or 3×3 inches.

Time and position data synchronized with GPS. Real-time gamma dose rate measurement is based on recalculation from spectrum. Accumulation time is selectable by the user starting from 1sec. The module offers internal data storage in the main unit as well as a wireless real-time data transfer to the control unit (Laptop) with Drone SW application. The operational time with internal battery is about 4 hours.
