Maybe we’re doing a better job of monitoring for nukes domestically than I thought. A woman was pulled over in her SUV for being radioactive:

“These are very sensitive devices,” Seymour said, adding that some officers have reported them going off in buildings “because someone in the next room on the other side of the wall had a stress test.”

Doctors said they have heard of radiation sensors going off at nuclear plants after patients have had stress tests, but not along highways…

…”Nobody at my doctor’s office warned me this could happen,” the woman said she told the officer. “He said, `That’s because they don’t know.'”
