☢️ Strahlungsarten Überblick | Alpha-, Beta- und Gammastrahlung

👇👇👇 Decay Types ☢️ Alpha Decay: α = 2p + 2n A helium nucleus is emitted (2 protons, 2 neutrons). The mass number decreases by 4, and the atomic number decreases by 2. [A⁻⁴, Z⁻²] ☢️ Beta-Minus Decay: n → p + e⁻ + antineutrino A neutron transforms into a proton, emitting an electron in the process. The mass number remains the same, but the atomic number increases by 1. [A⁻, Z⁺¹] ☢️ Beta-Plus Decay: p → n + e⁺ + neutrino A proton transforms into a neutron, emitting a positron in the process. The mass number remains the same, but the atomic number decreases by 1. [A=, Z-1] ☢️ Gamma decay: X*(nucleus excited) → X + γ The nucleus releases energy as gamma radiation. Mass number remains the same, atomic number remains the same.
