Re: Contaminated Lead Products Update

The following is just an uneducated guess:

Assuming that the smelter byproduct material in question is a slag type
material,  that this material actually forms on top of the melting
feedstock,and there is no chemical separation of the U, Th or Ra during the
smelting process.

Is it then possible that the Radon eminating from the melting feedstock gets
trapped during the formation the slag material and that the high
concentration of the Pb-210 is a result of the low slag to product ratio?

It seems to me that for the same reasons Radium is not present in the Natural
Gas filters or pigging materials while Pb-210 is that the same explanation
holds true here. That being the decay of essentially "trapped" Radon in the
slag.  Since the source of Radon is cut off upon slag removal, in a couple of
weeks all that remains in the slag is Pb-210.
