Alpha radiation: Particles. Each alpha particle is a little bundle of 2 protons and 2 neutrons ... identical to the nucleus of a Helium atom.
Charge . . . +2 elementary charges
Mass . . . 4 Atomic Mass Units
Relative penetrating power . . . low
The effect an electric field would have on it . . . Since the alpha particle has a positive charge, it's repelled by other positive charges, and attracted toward negative charges.
Beta radiation: Particles. Each beta particle is an electron.
Charge . . . -1 elementary charge
Mass . . . 0.00055 AMU
Relative penetrating power . . . medium
The effect an electric field would have on it . . . repelled by other negative charges, and attracted toward positive charges.
Gamma radiation: electromagnetic wave, verrrrry short wave, high frequency
Charge . . . electromagnetic wave, no charge
Mass . . . electromagnetic wave, no mass
Relative penetrating power . . . high
