GT4

Defentect's GT4 is a scintillator-based gamma radiation sensor enabling real-time alerts and gamma radiation isotope identification in an unattended perimeter or portal network. If threat-level violations occur during a high gamma radiation count event, isotope ID and date are sent to DM3, triggering an alarm. GT4 combines passive surveillance with active alarms and can be set to ignore medical or other benign environmental isotopes. Even high radiation areas may be monitored since the system automatically subtracts predictive background radiation. Set in 'patient mode,' individuals undergoing medical treatments pass without triggering innocent alarms.
