Answer:
Alpha radiation particles are big, heavy, slow and weak. Because they are so big, they bash into atoms and knock electrons off - this creates ions. They are too weak to penetrate, but once breathed in, it causes damage internally. ALPHA particles are POSITIVELY CHARGED.
Beta radiation particles are small, medium-weight, and fast. For every Beta-particle emmited, the number of protons increased by one. BETA particles are NEGATIVELY CHARGED.
Gamma radiation particles are tiny, have no weight and are really fast. Gamma particles don't really hit or collide with anything, they usually pass through although it does damage. They enter the body via penetration and causes damage before leaving the body. GAMMA particles have NO CHARGE.
