The Department of Homeland Security has awarded Washington, D.C., a $30 million grant to expand its ability to detect and deter nuclear and radiological threats.

The grant, which will be distributed to Washington over five years, was made by DHS' Domestic Nuclear Detection Office, which runs a program called Securing the Cities. That program started in 2006 and provided aide to New York City, and was then expanded to the Los Angeles/Long Beach area.

The District of Columbia's Homeland Security and Emergency Management Agency will use the grant money, which will be $6 million in 2014. Chris Geldart, the director of that office, said the money would help the city "continue to build robust nuclear detection capabilities that will protect citizens, businesses and visitors throughout the nation's capital."

Geldart also said it would help provide equipment and fund training efforts.

DC Mayor Vincent Gray said the city would use the money to "further reduce risk along our area roadways, rail and maritime pathways."

"The funding will allow the District to work with partners in the National Capital Region to build a robust, regional nuclear detection capability for law enforcement and first responder organizations," DHS said. "Initial efforts will focus on analyzing the region's current capabilities and planning for post-program sustainment activities."
