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. www.epaosc.net/aspectgem EPA Homeland Security 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.” ASPECT GEM Project www.epaosc.net/aspectgem Univ. of Cincinnati EPA LANL Univ. of Iowa NDT ASPECT Pilots DOE FRMAC RERT NDT: National Decontamination Team ERT RERT: Radiological Emergency Response Team ERT: Environmental Response Team ORIA ORIA: Office of Radiation and Indoor Air NHSRC NHSRC: Nat.
