Here also is found monazite, which is mined to some extent.

It is mined with the shovel and pick, the soil and underlying gravel containing the monazite being thrown upon a perforated iron pan at the head of a sluice box, and as this is washed down by a current of water the monazite, which is nearly twice as heavy as ordinary sand, quickly settles to the bottom and is easily separated from the latter.

At the Kulyk Lake showing, a series of red secondary fracture fillings has returned historical values up to 0.22 per cent U3O8 and 1.28 per cent Th. No historical analyses for REE's have been reported, but petrographic work indicated the presence of important REE carrier minerals such as monazite and the heavy rare earth element

And there are plenty of studies which show no correlation between low doses from natural causes (both from high-altitude, such as residents of Denver, as well as people living in radiation-rich soil regions, such as the monazite sands in India).

In the 1950s and 1960s most rare-earth mining occurred in South Africa, India and Brazil where the elements were primarily extracted from the mineral monazite (see chart).

ruzuzu commented on the word monazite
"To garner more evidence for a Jurassic-era, continent-crossing river, researchers could scour ancient sandstones for other erosion-resistant minerals such as monazite, Scott D. Samson says. Bits of that mineral are rarer than zircons but have a distinct chemical signature that could help researchers pin down their origins, he notes."
