Key Technology: HPGe Detectors •
ORTEC is a world leader in nuclear instrumentation, including both growing HPGe crystals and fabricating detectors.
•
ORTEC has significant experience in large scale production of HPGe detectors for a variety of projects.
3
Key Technology: DSP Hardware ORTEC was first to commercialize Digital Signal Processing (DSP) technology in an integrated gamma ray spectrometer.
ORTEC holds nine separate patents in the area of DSP based MCA technology alone.

The Cost of False Alarms •
False Positives (nuisance alarms) – 90% of innocent alarms at airports are due to medical isotopes in the bodies of travellers
– In cargo/freight, the major problem is caused by natural emitters. – “Suspending operations in just one terminal for just one hour could cost close to $500,000,” said Bethann Rooney, Port Authority’s Manager of Port Security, New York Harbor.
