October 4, 2004—Axcess International has just announced a distributed radiation detection and alerting system based upon its battery-powered Radio Frequency Identification (RFID) long range wireless tagging technology. The radiation detector and alerting system provides constant monitoring for harmful gamma radiation emitting from sources which may be used in a terrorist “dirty bomb” attack. The system was demonstrated at the recent ASIS Annual Seminar and Exhibits show in Dallas, Texas.
The use of distributed, portable radiation sensors and a wireless monitoring network provides an effective blanket detection coverage area where portal-based systems cannot, explains Axcess. The detectors and transmitting RFID tags are both battery powered, so sensors can be easily populated in the open areas of cargo ports, airports, and borders to detect emissions from containers, vehicles, and people carrying hazardous radiation sources.
The use of active RFID tags to transmit detection signals combines with the detectors for a very low cost wireless monitoring network, able to analyze critical data from a vast array of detectors, alert responders immediately, and support immediate evidentiary investigation.
The network-based solution integrates the RADITECT detector with the Axcess ActiveTag wireless sensor technology. The ActiveTag RFID unit can detect the presence of radiation equal to a single x-ray. A single detection unit or multiple units networked together can be monitored by an infrastructure of RFID receivers connected to the network or the Internet using Axcess’ Onlinesupervisor software. Alarms are displayed visually and graphically on a map. Alert notifications include alarms, pages, and e-mails to local personnel and authorities.
The Onlinesupervisor software can support multiple types of sensors including temperature, pressure, movement, intrusion, biological, chemical, and nuclear. Since the system is integrated with Axcess’ Prism Video line of network-based digital video products, video verification of an alarm will enable security officials to quickly view an actual event and allow them to provide quick response and proper intervention.
