The United States and Singapore have agreed to cooperate on the Secure Freight Initiative, which is a Department of Homeland Security led effort at select foreign ports to scan U.S.-bound cargo for radiological materials, Customs and Border Protection said this week.

The Port of Singapore is part of a second group of international ports under Secure Freight that is evaluating integrated radiation detection and non-intrusive imaging capabilities on a limited basis. Secure Freight was mandated by Congress.

Data obtained from the scanning equipment is provided in near-real time to CBP officials on-site and to officials at the National Targeting Center in the U.S. for analysis.
