🅱️ Beta Radiation (β)
-
Beta radiation occurs when a neutron converts into a proton or vice versa, consisting of electrons (β-) or positrons (β+).
-
- Range: Beta particles can travel several meters through air, thus have a much greater range than alpha radiation.
- Penetration: Medium – they can penetrate a few millimeters into tissue and are shielded by a few millimeters of aluminum or plastic.
- Hazards: Beta radiation can cause burns and skin damage upon external contact. Inside the body, it can damage deeper cells and thus increase cancer risk.
- Safety Measures:
- Work behind plexiglass or aluminum shields.
- Wear clothing that covers skin and use gloves.
- Always handle radiation sources with appropriate tools and never directly.
