Princeton Security Technologies, Inc. (OTCBB: PSGY), Completes Radiation Sensor Testing on Large Displacement Unmanned Underwater Vehicle (LDUUV) With Boeing

Underwater Measurements of Naturally Occurring Radiation in Sea Water off Catalina Island, California

PRINCETON, NJ--(Marketwire - Jan 24, 2012) - New nuclear radiation detection tools from Princeton Gamma Tech Instruments (OTCBB: PSGY) were included in a series of tests performed by the Boeing Echo Ranger, autonomous underwater vehicle (AUV) during recent testing in the Pacific Ocean, off Catalina Island, California. The test campaign allowed spectroscopic monitoring of the seabed. The cooperative effort included engineers from both organizations combining best practices to perform ultra-low level isotope discrimination that is naturally occurring in the Pacific Ocean.

Applications for advanced nuclear radiation detection and underwater isotope identification include uranium exploration, underwater vessel interdiction and border security. PGT offers a patented technology for background subtraction which allows levels down to 100X below background to be identified, as well as isotope category and isotope specific dose rates.

"As an AUV service provider, we gained important knowledge about the near-term prospect of combining Boeing's high-level autonomous behaviors with PGT's rapid on-board processing for a truly autonomous undersea radiological search capability," said Jameson Garrett, program development manager with Boeing Information Solutions, part of Boeing Defense, Space & Security.
