The alpha particles are capable of alternating the mass and atomic numbers in the atoms which is responsible for transmutation. This occurs in nuclear reacting.
Transmutation occurs in any process where the no. of protons or neutrons in the atom are changed.
Transmutation occurs when conversion of one element occurs into others.
There are three kinds of radiations gamma, beta, and alpha.
Both beta and alpha are capable of transmutation as they are capable of changes in the atomic and mass numbers.
