       Top Ten Features

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

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

3.   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.
     Top Ten Features

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.

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

7.   Individual Crystal Linearization with
     proper Poisson noise characteristics
      Top Ten Features

8.    Expandable
      Unlimited number of crystals (limited only by
      weight considerations)

9.    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.

10.   Modern Compact Design – Strong &
      Efficient Case, Modular, Meet FAA
      requirements
  ASPECT GEM Project
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.

ASPECT GEM project directly supports
 the EPA Office of Homeland Security
 focal area that directs the agency to:
 ”Develop appropriate/effective
 technologies to lessen the time frame
 for characterization and
 decontamination of contaminated
 widespread and populated areas
 following an RDD.”
