Uranium is a radio active element and it was discovered in 1789 by Martin Klaproth. This extraordinary element can produce 40+ million kilowatt hours of electricity and it is actually equivalent to burning 16,000 tons of coal.
Excessive exposure to Uranium radiation is extremely dangerous to humans because it can cause cancer. This is why it is called the deadliest metal on earth.
To demonstrate Uranium radiation, this apparatus called the cloud chamber can be used. It is used to detect ionizing radiation and contains supersaturated vapor of water in a sealed environment.
When the radioactive particles go through this vaporous environment, they collapse with the molecules in their path, causing the formation of these amazing trails inside. Checkout this video and you will see how beautiful it is.
If we think about the path weights, Alpha particles give off small fat trails, beta particles produce longer and thinner trails, and gamma particles give off the longest and thinnest trails.
In-fact, not all the radiation paths in here is dangerous. Alpha particles emitting from Uranium can be stopped easily because it has the highest weight from all the particles. Beta particles are lighter so it can penetrate in to body easily. Gamma is absolutely dangerous because it can damage the cells inside human body.
Honestly, this is just a harmless rock with negligible amount of radiation.
Do you know what else is radioactive?
The sun, the soil and even the water we take. You might be surprised, bananas are radioactive.
But there is no need to worry because only a large amount of Uranium can cause diseases to our body.
These little trails in the demonstration are not really dangerous so you can even build your own cloud chamber and try this at home.
