Department of Homeland Security Awards Charles River Analytics Contract to Track Nuclear Threats in Urban Environments

Charles River Analytics was awarded a $1M follow-on contract from the Department of Homeland Security in 2019 to develop a prototype of TNT-SCAN, a security system that offers continuous, real-time monitoring of radiological sources in complex urban environments and public venues.

Current security systems that automatically detect and track radiological threats produce too many false alarms, placing a high operational burden on personnel. Also, ambiguities about the current location of a viable threat, particularly in a cluttered urban environment with many moving objects, limit the ability of security personnel to respond effectively.

TNT-SCAN combines advanced video analytics with data from radiation sensors to detect objects of interest in a monitored area and track them in video streams provided by a local video management system. The system automatically identifies and localizes threat sources,  displaying  this information to security personnel for review, verification of severity, and assignment of appropriate law enforcement action via an intuitive user interface.

The TNT-SCAN security system can be integrated into new and existing security networks, allowing operators of security infrastructure to seamlessly augment their networks with new, state-of-the-art radiation monitoring capabilities.

“TNT-SCAN aims to make threat response capabilities widely available and affordable to organizations safeguarding the public,” said Camille Monnier, Principal Investigator of the TNT-SCAN effort.
