Helium is an incredibly diverse and fascinating element. It is the second lightest element in the universe, only behind hydrogen, and has one of the smallest atomic radii of any element, making it a particularly unique substance to explore. While many are familiar with helium as a party trick or from balloons, there is much more to learn about this miraculous gas.
One of the most striking properties of helium is its incredibly low boiling point. At just -268.9 degrees Celsius, helium will transform from a gas to a liquid – a state that is incredibly useful. To this end, helium has a range of applications in industries such as healthcare, space, and natural gas recovery.
In healthcare, the use of liquid helium can be traced back as early as 1960, where it was used as a coolant for magnet resonances and as a cooling agent in radiation therapy. More recently, medical professionals have started to explore its potential in cryosurgery, a type of surgery to freeze and destroy diseased tissues.
In the space industry, helium is used in large quantities for cooling and pressurization of liquid-fueled rockets. Helium is an excellent coolant due to its uniquely high thermal conductivity, making it ideal for use in critical processes that require great precision.
Likewise, the natural gas industry utilizes helium for leak detection because of its light atomic size and relative chemical inertness. There is also a growing interest in using helium as a fuel for nuclear energy, given the fact that it can burn without releasing greenhouse gases such as CO2.
While it may be easy to think of helium only as a rubber balloon filler, the truth is that this fascinating gas has a range of properties and uses that are just beginning to be fully understood. Whether used in healthcare, space exploration, or natural gas recovery, the properties of helium make it an outstanding choice, offering significant benefits over other substances. From its remarkably low boiling point to its incredible thermal conductivity, there are many reasons to explore the fascinating world of helium.
