What is helium used for? Helium is put into balloons to help float Helium is easily detected in minute quantites, and has a very small molecule. So helium is also used for checking vacum and other â¦enclosures for leaks. Helium is used in some noble gas (neon) signs, possibly mixed with other gases. Liquid helium is used as a coolant, like for MRI magnets and such. Liquid helium acts as a study in physics for superfluids (see link below).
