Most rare earth minerals are conjoined with cancercausing radioactive elements like thorium. Another thing to keep in mind about the nature of REE mining is that almost all REEs are bound to radioactive substances in the ground from which they have to be separated in order to be used in "green energy" technologies and consumer products.

Rareearth element Rareearth element Hydrides: The rareearth metals readily react with hydrogen to form RH2, and, by raising the hydrogen pressure, the trivalent R metals (except for scandium) also form the RH3 phase. Both the RH2 and RH3 phases are nonstoichiometric (that is, the numbers of atoms of the elements present cannot be expressed as a ratio of small whole numbers).
