Sirens Around Indian Point Nuclear Plant Successfully Tested

BUCHANAN, N.Y. (CBSNewYork/AP) -- This is only a test.

The 172 sirens that dot four counties around the Indian Point nuclear power plants sounded-off in a four-minute test Wednesday.

The sirens are designed to alert everyone within 10 miles when there's a serious problem at the plant. But they have to be tested to make sure they will work when needed.

There are 77 sirens in Westchester County, 56 in Rockland, 23 in Orange and 16 in Putnam.
