What is alpha radiation?

Alpha radiation involves the fragmentation of the nucleus into two particles, one consisting of two protons and two neutrons (an alpha particle, or in other words, a helium nucleus), and the other consisting of the remaining protons, neutrons, and electrons initially present in the parent nucleus. Alpha decay decreases the number of protons in the nucleus by two and decreases the atomic mass of the nucleus by four amu.
