More than 100 police and other first responder agencies in /*New York*/, /*New Jersey*/ and /*Connecticut*/ participated in Saturday's exercises.
During the operations on land and rail, more than 100 radiological "sources" were intercepted in and around New York City.
The drill was aimed at assessing agencies' preparedness for detecting and intercepting radiological devices before they can wreak havoc on /*Wall Street*/ and other high-profile targets in /*Manhattan*/, the heart of the nation's largest city.
The New York City Police say that all efforts to bring radiological devices into the city from the surrounding region were thwarted during the drill.
