Alpha Emission When a nucleus emits an alpha particle (identical to a helium nucleus) thus making itself less unstable.
Beta Emission Basically a neutron in the atom becomes a proton and electron, but the proton being positive (and larger) throws the negative electron out of the atom.
Positron Emission A positron emission is when a positron is emitted from a nucleus, after a proton is converted to a neutron. go figure!
Electron Capture This happens when an electron is absorbed by a proton, causing it to become a neutron.
Gamma Emission A gamma emission is when the slight excess of energy from another emission is converted to gamma rays, and ejected along with it.
Conclusion All radiation is the ejection of particles in order to stabilize the atom. Stabilization means the atom transforms into a different isotope.
