Slightly OT: how to test magnetrons?

I tried taking a few to my scrap yard, but they wouldnt take them. I first tried as electric motors and was denied. And as you drive on the scale there is a giant radiation detector that you drive through. So I basically had to throw them all out

What exactly is radioactive in a magnetron? There is just two magnets, copper, AL, and etc inside one. NOTHING that would set off a scrap yards radiation detector.

My scrap yard takes them as electric motors, so I don't have a problem, but if they didn't I'd stuff them in with a load of mixed metal without worry.
