<u>Alpha radiation</u> is a type of airborne particle that rapidly loses energy as it moves through the atmosphere, has weak penetrating strength, and can be prevented by clothing or a piece of paper.
<h3><u>Why does alpha radiation exist?</u></h3>
Two protons and two neutrons are bonded together to form an object resembling a helium-4 nucleus, which is what is known as an alpha particle, also known as an alpha ray, or alpha radiation. Although there are additional possibilities, they are often created during the alpha decay process.
The Greek letter, which begins the alphabet, is where the name "alpha particle" originates. Alpha is represented by the sign 2+. Net spin is zero for alpha particles. Alpha particles typically have a kinetic energy of around 5 MeV and a velocity in the area of 4% of the speed of light because of the mechanism of their generation in ordinary alpha radioactive decay.
