My big vintage radio tubes are radio-active! (Patreon)

I didn't know, but when Antoine visited and I showed him the big tubes from the previous post, he immediately told us the glass seals on my tube probably contained Uranium because they looked greenish. And therefore would be radio active. Gulp. To which Ken asked, would they then glow in UV light? I plugged a black light bulb in my workbench light fixture, and we all went oooh and aaaah as the portions made of Uranium glass started to light up in ghostly green! Now that's a bit more scary than the Berylium ceramic. This is for real!
