Non-Threshold - Any dose produces a response Thermionic Emission - Filament electrons are boiled off producing an electron cloud Bremsstrahlung - AKA Breaking Radiation. Occurs when a high speed electron from the cathode is deflected by the nucleus of a target atom Characteristic Radiation - Occurs when cathode electrons dislodge inner orbit electrons from the target atoms. Anode Heel Affect - Reduction of beam intensity due to interaction with heel of target Quality - Refers to penetrati...
