So are some isotopes of thorium.

Oh, there's another problem. Various phases of the

Radium is the source of radon. The problem is its intense
radioactivity. Indeed, a gram of radium defines the Curie, the
traditional measurement of

I'll go with the rogue tube explanation. The affected tube didn't glow any
brighter, nor did it glow in a different color. Anyway, I cannot check the
I don't think Pb-210 (being a decay product of Rn-222) will ever produce
Rn. Perhaps the best bet (and still very unfeasible) is Radium Ra-226 which
decays directly into Rn-222 via alpha decay with a half life of 1.6 kyears.
(That's how the first emission spectrum of Rn was obtained.) That

Interesting, but € 75,- is a bit expensive……

Lots of basements with radon to spare... Too bad you can't
