Q. Explain about beta radiation?
The second common kind of radiation is beta radiation which consists of high-energy electrons called beta particles (β -particles).
It is significant to realize that each of these beta particles is emitted by the atom's nucleus thereby increasing its atomic number (and charge) by 1.
