NORWALK, Conn., March 31, 2008 (BUSINESS WIRE) -- Splinternet Holdings, Inc., (OTC BB: SLNH.OB) will introduce three new entries in the wide-area radiological detection marketplace, DefenTect^TM, GammaTect^TM and GammaTect Plus^TM, at the Sands Expo and Convention Center in Las Vegas, April 2 - 4.

The systems will be demoed in Booth 9075, the OnSSI - On-Net Surveillance Systems, Inc. booth - at the International Security Conference and Exposition ISC West Show, where over 1,000 exhibitors and 24,000 security professionals will show their newest security products.

DefenTect^TM manages a distributed network of solid state GammaTect^TM radiation sensors, that send real-time notifications to security command centers when the presence of threat-level gamma rays is detected. The integrated DefenTect^TM system enables customers with IP networks to add radiation detection capability, increasing the utility of their security systems. Sensors can be strategically positioned adjacent to existing cameras to identify threats visually.

Integral to DefenTect^TM is a messaging system that sends customized alerts when any anomaly is detected. Administrators can designate alerts to be triggered to cell phones, pagers, PDAs or other devices through text messages, calls or e-mail. Dispersed GammaTect^TM sensors can be hidden under ceiling tiles or in walls to prevent compromise by terrorists. Testing indicates that the sensor detects gamma radiation at 2mR/hr in less than one second. This means a GammaTect^TM sensor will detect a dirty bomb made with 60 curies of Cesium-137 at a distance of 83.82 meters, or 275 feet.

GammaTect Plus^TM is a highly sophisticated gamma sensor with more sensitivity than GammaTect^TM sensors. GammaTect Plus^TM enables real-time isotope identification and can be set to ignore medical or other benign environmental isotopes to prevent triggering innocent positives. Even high radiation areas may be monitored since the system automatically subtracts predictive background radiation.

Splinternet's unattended radiation surveillance system, DefenTect^TM , integrates monitoring and active alerts in a ubiquitous wide-area sensor network, decreasing dependence on security personnel. DefenTect^TM is a homeland security solution designed to be installed at seaports, airports, trucking and shipping facilities, landmark buildings, hospitals and borders. Quantities of radiological materials stored at hospitals and food irradiation plants could be used by terrorists to create dirty bombs which if deployed, would cause drastic psychological, sociological and economic devastation.
