Ever wondered what radiation looks like? If you haven’t, better witness this mesmerizing process of decay and radiation emission from a small piece of Uranium.
Going back to Chemistry, Uranium is a weak radioactive element. It is a very heavy metal which can be used as an abundant source of concentrated energy. The element is 18.7 times as dense as water. The isotope Uranium-235, under certain conditions – can readily be split, yielding a lot of energy.
When Uranium is put inside a cloud chamber, it’ll start to decay and emit radiation. A cloud chamber, on the other hand, is a sealed glass container cooled to -40°C, topped with a layer of liquid alcohol.
According to Cloudylabs, the vapour emitted from the alcohol fills the container below, and most of it condenses on the glass surface, but some of it will remain as a vapour above the cold condenser.
This creates a layer of unstable supersaturated vapour [layer of alcohol] which can condense at any moment. When a charged particle crosses this vapour, it can knock electrons off the molecules forming ions. It causes the unstable alcohol vapour to condense around ions left behind by the travelling ionising particle. The path of the particle in the matter is then revealed by a track composed of thousands droplets of alcohol.”
Hence, the result is something that appears to be a CGI (Computer-generated imagery) with tiny particles shooting off in every direction, but what you see is reality.
Folks, you don’t have to be a science buff to appreciate this video showing how a small piece of uranium would emit radiation. In fact, after watching this mesmerizing process of decay and radiation emission, you’ll wish you’re an avid learner of science yourself.
This video definitely gives us a slight hypnotic effect. Oh science, you never fail to amaze us!
