Interaction of Radiation with Matter Radiology Key

WebBiological effects of any radiation increase with the linear energy transfer (LET) were discovered. In short, the biological damage from high-LET radiation ( alpha particles, protons, or neutrons) is much greater than that from low-LET radiation ( gamma rays ). This is because the living tissue can more easily repair damage from radiation ... Webradiation are alpha, beta, gamma, X, and neutron rays. Charged-particle radiation, such as alpha or beta rays, has a direct ionizing effect; whereas neutral radiation, such as X, gamma, or neutron rays, have an indirect ionizing effect, i.e. these radiations first generate charged particles which then have the ionizing effect. chil tewkesbury
