[Boatanchors] Receiver Antenna Input Question

[Ken Kaplan]

John,

What radioactive material is in an NE-2? I thought it was just neon (which is not at all 
radioactive). Of course there is some smoke in there somewhere even if you can't see it. 
Seems like smoke is the major component of all electronic devices.
