Alpha Radiation The release of an alpha particle during nuclear decay Alpha particles are HELIUM-4 particles! Example: the alpha decay of Beryllium-8

Example The decay of americium Am  He + Np

Beta Radiation The release of a Beta particle during nuclear decay A Beta particle is a LONE ELECTRON! During beta radiation the number of nucleons does not change, but the atomic number does! Example: Beta decay of Beryllium-10 Example 2: beta decay of Carbon-14

Gamma Radiation Gamma radiation consists of a stream of gamma photos – the most electromagnetic radiation Very damaging Example: both beta and gamma decay of Cobalt-60
