Industrial Networking Products

Is a security technology firm specialising in Radiation detection, messaging and alert systems.

Systems also manage event detectors including chemical, biological, nuclear and explosives sensors.

Committed to playing a critical part in the protection network to safeguard facilities that store & use radiological source material, against leakage & terrorism.

Gammatect DM3 ^TM

When high-energy gamma rays from potential dirty bomb components interact with Defentect's Gammatect™ sensors, The DM3’s^TM proprietary algorithms analyze the data and alert relevent authorities and personel to radiation that may pose a potential security or health threat.

Communication features of DM3^TM provide the ability to receive and process data over a network from the radiation sensor to the command center as well as to PDAs, mobile phones or pagers.

The addition of strategically placed Gammatect Plus^TM sensors enables DM3^TM to identify and isolate the specific isotope causing the radiation, providing control over false positive alarms.

The Defentect DM3^TM intelligent threat awareness network can offer unattended detection alerts and messaging for a variety of threat-event detection demands including CBRNE.

Gammatect^TM Sensor

The Gammatect^TM sensor offers gross gamma radiation detection for threat level sources. The amount of radioactivity that these sensors are designed to identify are levels that would be used in a terrorist attack. Gammatect^TM sensors are designed to be deployed in a broad network to provide early warning and situational awareness. Gammatect^TM sensors detect gamma radiation above 20 mR/hr in less than one second and will detect a dirty bomb made with 60 curies of Cesium-137 at a distance of 29.5 meters, or about 100 feet. Sensors can be positioned adjacent to and interact with security cameras to provide visual identification of a threat. Gammatect^TM sensors can be concelled / hidden above ceilings or behind walls to prevent compromise.

Gammatect^TM sensors have been validated by the internationally regognized Oak Ridge National Laboratories and other highly respected commercial radiation laboratories throughout the world.

Gammatect Plus^TM Sensor

Gammatect Plus^TM is scintillator-based and enables real-time alerts and gamma radiation isotope identification in an unattended perimeter or portal network. During a high radiological count event, the isotope ID and date are sent to a predetermined remote command center, triggering an alarm. System administrators can designate alerts to be triggered to PDAs, Cell phones, Pagers or other mobile clients using Defentect’s DM3^TM.

User friendly Gammatect Plus^TM combines passive surveillance with active alarms and can be set to ignore medical or other benign environmental isotopes. Even high radiation areas do not present problems and may be monitored as the system has the ability to automatically subtract predictive background radiation levels and when set to 'patient mode,' individuals undergoing medical treatments with high levels of radiation are able to pass without triggering innocent alarms.
