They can take uranium and convert it to uraninite, a nearly insoluble substance that will sink to the bottom of a lake or stream.

Uranium is present as disseminated uraninite within paragneisses, pegmatites and granites along a series of NW-SE hills averaging more than 65 m in height.

Radium is found in tiny quantities in the uranium ore uraninite and various other uranium minerals, and in even tinier quantities in thorium minerals.

It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite.

Helium was also isolated by the American geochemist William Francis Hillebrand prior to Ramsay's discovery when he noticed unusual spectral lines while testing a sample of the mineral uraninite.
