HELIUM GAS

Helium gas is a colourless, odourless, tasteless, non-toxic gas. It is relatively rare in our atmosphere equating to approximatley 5 ppm by volume. Helium is formed by the radioactive decay of heavy elements such as thorium and uranium. This radiogenic helium is trapped with natural gas deposits and can be concentrated up to 7% by volume. Commercial extraction involves the use of semi-permeable membranes and  low-temperature fractional distillation.  Helium is transported in a liquid form at temperatures of -269 degrees Celcius.

Helium is mainly used in its liquid form (cryogenics) for the cooling of superconducting magnets found in medical scanning instruments.

Inhaling helium can be dangerous, helium displaces oxygen needed for normal respiration and should not be attempted by any person.
