Symetrica, in conjunction with its prime partner Leidos, has deployed two latest generation radiation portal monitors to the port of North Charleston, South Carolina. In 2021, Leidos and Symetrica were awarded one of two 100+ portal contracts to deliver these systems over the next 18 months.
This deployment is the final phase in a 10-year effort by Symetrica and DHS CWMD to upgrade the radnuc monitoring and detection capability on the U.S. borders and ports. These RPMs offer increased sensitivity to nuclear threats whilst minimising nuisance alarms due to natural background radiation and Naturally Occurring Radioactive Material (NORM) shipments. The portals feature continual communication of system health and are the only systems to have active, continuous internal stabilization.
