US conducts domestic anti-terror radiation program

A classified radiation monitoring program, conducted without warrants, has targeted private US property in an effort to prevent an al-Qaida attack, federal law enforcement officials confirmed Friday. While declining to provide details including the number of cities and sites monitored, the officials said the air monitoring took place since the Sept. 11 attacks and from publicly accessible areas - which they said made warrants and court orders unnecessary. The American news weekly, US News and World Report first reported the program on Friday. The magazine said the monitoring was conducted at more than 100 Muslim sites in the Washington, DC area - including Maryland and Virginia suburbs - and at least five other cities when threat levels had risen: Chicago, Detroit, Las Vegas, New York and Seattle.
