What happens to the nucleon in an alpha radiation?

The question is stated above. Can someone please tell me what happens to it in an alpha radiation? The question is out of 2 marks so I think there might be more than 1 answer.What happens to the nucleon in an alpha radiation?
Perhaps the question should be what happens to the NUCLEUS in an 伪 radiation.

A nucleon is one of the particles in the nucleus of an atom - either a proton or a

neutron. An alpha or 伪-particle is the nucleus of a helium atom, and it contains 2

protons and 2 neutrons, so its mass number is 4.

Some heavy elements like uranium that have large nuclei can change into other

elements by emitting 伪-particles. If a nucleus emits an 伪-particle, its atomic number

decreases by 2, since it has lost 2 protons. Its mass number decreases by 4, since

it has lost a total of 4 nucleons - 2 protons and 2 neutrons.

I hope this explanation helps; it's the best I can do for your question as asked.
