What It Is! (A Magnetron)

RADSAFERs,

Thanks for the assistance and interest in finding out what kind of tube we
had come across.

After several conversations with (old) radar operators and a couple of
archivists from Raytheon (the tubes manufacturer) I found out what it was.

The tube can be viewed at:

We also found that the radiation reading (~3 times background with a
pancake probe) is from the Thorium which was applied under extreme heat to
the tungsten cathode.  They only made this type of tube for a few years in
the 1950s.
