At the Norfolk International Terminal, which is one of three cargo terminals managed by the state-owned Virginia Port Authority, any container exiting the terminal on a truck goes through a fixed radiation portal monitor.
The Norfolk terminal also has a rail yard with two chokepoints, one on the south side and the other on the northern end. Last month CBP set up a mobile radiation portal monitor supplied by SAIC at the southern end of the rail yard to screen containers that had been offloaded from ships for delivery by trucks to a rail car. Soon a similar set up will be deployed at the north side of the rail yard.
If the next-generation of radiation portal monitors are certified and deployed, the rail yard would probably be equipped with an Advanced Spectroscopic Portal for secondary inspection, Laria says. All this has yet to be decided, he adds.
