Facts About Gamma Rays Everyone Needs to Know
We all have heard the word gamma rays or gamma radiations and we have also learned about it at some point in our lives. Nevertheless, you will not be aware of these amazing facts about gamma rays which this post shares.
To be simple, gamma rays are the part of the electromagnetic spectrum and not just any simple form of radiations but the most energetic form of lightning that is found in the universe. They are such high energy waves that it can easily pierce a metal or concrete. Following are the facts that you should know about gamma rays.
1. Gamma-ray bursts
Gamma rays are the cause of GRBs that is gamma rays bursts. When GRB happens, they are the brightest thing that can be seen in the universe from the Earth. It can occur in any part of the universe at any time.
GRB happens when there are some bursts in the world and the time span of the GRB depends upon the event that caused it. Short GRBs remains for only seconds and are the result of neutrons stars collision.
Long GRBs can be viewed for a minute, and it is believed that it results from the supernova of a star. GRBs are powerful and dangerous enough to roast the planet earth if they happen near it.
2. Surgeries with gamma rays
As gamma rays are mighty and can easily kill humans, nevertheless from a positive point of view, it is helpful in killing cancerous cells.
For eliminating brain cancers and other medical conditions, gamma ray knives are used. It consists of a beam of gamma rays applied to the cells that are harmful and must be destroyed.
As the gamma rays, knives are extremely focused as a result of which healthy brain cells remain untouched. Gamma-ray knives are considered a safer alternative to performing certain surgeries.
3. Gamma radiations on earth
On earth, a major source of gamma rays is nuclear reactions. In a nuclear fissions reaction, a uranium nucleus splits and produces a lot of gamma radiations. Moreover, lightning and thunderstorms are also a source of gamma rays.
Static electricity which builds up in the clouds is the particle accelerator and creates pairs of positrons and electrons which then result in gamma rays.
Other than that gamma rays provide light and life to earth. When hydrogen fuse into the sun, gamma rays are produced which then combine with protons and electrons and lose energy. This energy transforms into infrared, ultraviolet and visible light.
These lights are the reason for the warmth of the earth and life sustainability on earth. However, excessive exposure to gamma rays can be dangerous. Protection from gamma radiation is very important.
4. Gamma rays invented telescopes
In order to study gamma rays, scientists invented telescopes in space. Before these telescopes, it was challenging to explore these amazing radiations, as they were met with many atoms in their journey towards earth.
To observe the gamma rays, the simple lens could not have been used because they pass right through them, so individual telescopes were invented which converted gamma rays into electrons and positrons.
There are various other facts and benefits of gamma rays that we do not even know about. Experts are working hard to find new ways of using the rays for benefits of mankind.
