Top ten features
Top Ten Features Technology

  • Digital Design – More stable, less drift, higher count rates, “cleaner” spectra i.e. better data.

  • No Internal or External Test Sources – No radioactive material transport issues. No lost or misplaced sources.

  • Self Diagnostic with Auto System Validation – An Advanced design enables a more self contained system requiring less operator interaction. Individual detector raw data is archived in the system

    4. Multi-Peak U, K, Th Auto-Stabilization – Stabilizes in all areas, Faster, 3 min vs 30 min.

5. Individual Crystal ADC’s& Processing –

The high speed sampling of pulses allows for pulse analysis and DSP processing.

Resulting in improved pulse pile-up rejection, zero dead time & a higher throughput.

  • Wide Dynamic Range – From low level to 1,000,000+ cps for each crystal.

  • Individual Crystal Linearization with proper Poisson noise characteristics


Top ten features2
Top Ten Features Technology

  • Expandable

    Unlimited number of crystals (limited only by weight considerations)

  • Wide range of Connectivity options – RS232 serial, TCPIP and USB. Utilizing data compression that allows for full spectral data transfer every second over wireless devices.

  • Modern Compact Design – Strong & Efficient Case, Modular, Meet FAA requirements


Aspect gem project
ASPECT GEM Project Technology

Purpose: To improve the US EPA airborne gamma-screening and mapping capability of ground-based gamma contamination following a wide-area radiological dispersal device (RDD) or improvised nuclear detonation (IND) attack.

Goal: To develop the most advanced gamma-radiation detection capability mountable within an Aero Command 680 FL airframe.
