___ shell interaction has the highest binding energy and is the most useful for medical imaging - ANSWERk roentgen discovered radiation in - ANSWER1895 ionization - ANSWERthe process of adding or removing electrons from an atom or molecule, which gives the atom or molecule a net charge particulate radiation - ANSWERparticles that have mass and travel in straight lines fast NOT THE SPEED OF LIGHT neutrons protons electrons beta and gamma electromagnetic radiation - ANSWERelect...

what mag modes are available? - Answer if you have a 16" II, you can have 12,9,6, and 4.5 " Compton effect - Answer hits the outer electron, incomplete transfer of energy, electron released and a low energy xray is deflected photoelectric absorption - Answer x-ray totally absorbed by inner shell electron, x-ray overcomes binding energy and knock out the electron and an outer shell electron takes it place. When the outer electron moves to its new place, a characteristic x-ray is for...

The principal late effects of ionizing radiation on humans include tissue damage ic effects nant disease - ANS ic effects nant disease Late or long-term effects of radiation can occur in tissues as a result of chronic exposure or tissues that have survived a previous irradiation months or years earlier. These late effects, such as carcinogenesis and genetic effects, are "all-or-nothing" effects—either the organism develops cancer or it does not. Examples of late effects of ...

Limited Scope of Radiography Practice Exam - Questions with Verified Answers What statements are correct regarding the link between radiation and genetic effects? The link has been demonstrated in animal studies Increased risk to humans cannot be predicted with respect to an individual. The changes in kilovoltage (kVp) will result in the greatest reduction of patient dose, when milliampere-seconds (mAs) is adjusted to compensate for the change Increase kVp by 30% The following image receptor (...
