What forms of energy are released from the nuclei of radioactive atoms? Describe alpha beta & gamma radiation?

Alpha Radiation -----> 2 Protons & 2 Neutrons Bound together (also known as a Helium Nucleus)

Beta Radiation (Electron) ------> Fast Moving Electron
Beta Radiation (Positron) ------> Fast Moving Positron (The Electrons Anti-Particle)
Beta Radiation (Electron Capture) ------> Electron (Captured) + Proton = Neutron + Anti-Neutrino

Gamma ------> Energy in the form of an Electromagnetic Wave Emitted From the Nucleus of the Radioactive Atom. (Remember X-Rays are emitted by Electrons, Gamma rays by the Nucleus)

Hope this has helped out.....
