Thulium is useful in medicine as it can be bombarded in a nuclear reactor to create a radiation source for portable x-ray machines. In addition to medical uses, Thulium has applications as an energy source and in the magnets of microwaves as well as laser pointers, though it requires safe handling.

1. Thulium is a very useful element in the
medical field. After Thulium is bombarded in a
nuclear reactor, it can be used as a radiation
source in portable x-ray machines. Believe it or
not, this is only one of the many uses for this
element. It is also used for energy sources, in
the magnetic equipment of microwaves and even
fun stuff like laser pointers. (Just handle it with
care)
