The US and probably every other nuclear power in the world has aircraft and procedures for monitoring radioactive plumes. Not only can they detect and measure radioactivity levels, they can analyze the nature of the radioactivity and make a well-informed guess as to it's source, half-life and other things.

This was originally developed during the Cold War to track Soviet atmospheric tests.
