 == Description ==
-A rare-earth element of the yttrium group. Thulium was discovered in 1879 by P.T.Cleve, a Swedish chemist. It has an abundance of 0.48 ppm in the earth's crust. Thulium occurs in rare earth minerals such as euxenite, ytterspar, sipylite and gadolinite. It is a silvery-white, metal that is easily worked. Thulium is used as a radioactive source in small, portable x-ray machines.
