That is a "popular science" theory. But unlikely since only iron,
nickel, lead, copper, silver and gold are likely to be in metal (and
not salt) form within the earth, and so the dense elements, not
molecules, sink to the centre.
That's why we are convinced the earth core is nickel-iron (born out by
meteorites)
That's why we can mine uranium ores.


ok.


K-40 doesn't fission and so isn't part of a natural reactor


ok.


you mean, like 100 pCi/L worth of radiation is not building up in my house
by comming out of the ground (and passing right through this heavy piece of
plastic apparently designed to try to stop it)?...

That's due to radon from the near-surface fissioning elements.
You shouldn't try to block it, but rather ventilate it out of the
house though wall ducts.

workmen came and installed a special pump designed to suck it up and blow it outside...
