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 said, you would need quite a bit of Ra-226 to keep enough Rn in your tube, as half of Rn will decay in less than 4 days.
