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

I understand that with a half-life of 3.8 days, getting a discharge tube of
any appreciable size full of it would be problematic to put it mildly. But
is it possible to closely mimic its spectrum and thus make a "simulated"
radon tube?

Can You see if the mercury giver has released it's content? Did the failed
tube show any sign of a different color? I have a Telefunken ZM1210 where
the giver has not melted as it should. That tube lights up in a much more
reddish color than the OK ones. If there was an overcurrent or too long
I had a similar massive darkening on a IN-14 tube some years ago. Repalced
tube and it have working good since then. I supposed air have come inside
tube.

I did leave Rn out but not unintentionally. I'm not sure enough Rn has
ever been collected in one spot to fill the letters Rn. If that was
possible and the contents added to the tubing, viewing the "Rn" would be
your dying wish!
Of course, one could sprinkle some Pb-210 into the tube. That's th

You're right, I realized it after I posted it.

I'm guessing you're also missing Ra, but so is everybody els
A couple of possibilities to think about... Either you've got a rogue tube
where there is some manufacturing flaw that is markedly increasing
sputtering. Or there's a problem with the clock circuit which is allowing a
significant over-current through that tube specifically - maybe a current
