LRA 211 Questions and Answers | Latest Update | 2024/2025 | Rated A+ A negative ion is has more electrons than pr A positive ion is has more protons than electrons A radiographic image that is too light has ________________ to visualize the anatomic structures. excessive brightness After a photoelectric interaction, the incident photon loses all energy and no longer exist An increase in the image size of an object compared with its true, or actual, size, is called size distortion As a wave's wavelength increases, its frequency its frequency increases As the distance increases, the beam quantity reaching a specific area Decreases As the wave's frequency increases, the wavelength Decreases Attenuation of the x-ray beam in the diagnostic range is due to absorption and scattering Beam quality refers to the energy level of the radiation Bremsstrahlung means braking radiation By regulation, x-ray tube leakage radiation can be no more than 100 mr per hour at a distance of one meter Characteristic x-ray photons result B and C B. when an inner-shell electron is knocked outC. when outer-shell electrons fill the vacancy in an inner shell Compton scattering results in a compton electron, a secondary electron and a compton scatter photon Compton scattering typically occurs with x-ray photons in the energy range of 20-40 keV Dense material, like bone, is considered: radiopaque Distortion is a misrepresentation of the size
