The nucleus of a helium atom travelling at extremely high speed

How is a beta particle formed?
An atom decays into a daughter atom by changing a neutron into a proton and electron, but then the daughter atom emits an electron which is the beta particle

A fast moving high energy electron

Sum up the properties of the daughter nucleus
It gains a proton and emits an electron

How is gamma radiation formed and what is it?
After alpha or beta decay, extra energy is sometimes emitted which is gamma radiation. Gamma radiation is a wave with very high frequency and short wavelength.
