Unformatted text preview: Beta Beta particles are smaller and travel much faster than alpha particles. They are physically similar to the electrons discussed earlier in this unit, but they are not in orbit around an atom. Since beta particles travel faster and have less charge than alpha particles, they penetrate further into any material or tissue. Typical beta particles can travel several millimeters through tissue, but they generally do not penetrate far enough to reach the vital inner organs. Beta particles may be a major hazard, however, when emitted by internally deposited radioactive material or when interacting with the lens of the eye....
