How to shield beta radiation
WebCharacteristics of Shielding Radiation shielding is considered in two general classifications of thermal and biological, which are de-fined as: Thermal Shielding is used to dissipate excessive heat from high absorption of radiation energy, and Biological Shielding is needed to reduce radiation, e.g., gamma or neutron radiation, to a safe WebJul 1, 2024 · Vocabulary. Alpha decay - A common mode of radioactive decay in which a nucleus emits an alpha particle (a helium-4 nucleus). Beta decay - A common mode of radioactive decay in which a nucleus emits beta particles. The daughter nucleus will have a higher atomic number than the original nucleus.
