Helium is used for many purposes that require some of its unique properties, such as its low boiling point, low density, low solubility, high thermal conductivity, or inertness.
Helium is the second lightest element and is the second most abundant in the observable universe, being present in the universe in masses more than 12 times those of all the heavier elements combined. Helium's abundance is also similar to this in our own Sun and Jupiter.
On Earth, the lightness of helium has caused its evaporation from the gas and dust cloud from which the planet condensed, and it is thus relatively rare—0.00052% by volume in the atmosphere. What helium is present today has been mostly created by the natural radioactive decay of heavy radioactive elements (thorium and uranium), as the alpha particles that are emitted by such decays consist of helium-4 nuclei.

Helium Production
Most of the helium that is used comes from specific natural gas fields where it is in abundance, the largest concentration of helium trapped under the earths surface has been found here in Hugoton Natural Gas Area in Kansas The United States is the #1 producer of Helium in the World, and this has the highest concentration of helium because it is one of the largest natural gas fields in the USA.
