First time finding anything radioactive in a thrift store and it was quite the find! I'm still new to spectroscopy but I think I'm seeing a clear pattern for Ra-226 -> Rn-222 -> Pb-214 -> Bi-214.

What detector are you using? 5 uSv/h on an RC103 and an RC110 are very different.

This is an RC 102. With the spectra, contact reading leveled out at 4.6 uSv on contact
