Elsevier Adaptive Quizzes A radiologic technologist is working on barium and iodine. Which term does the radiologic technologist use to refer to 134/56 Ba and 131/53 I ? a. Isobar b. Isomer c. Isotope d. Isotone - d. Isotone Isotones differ in their atomic numbers and mass numbers, but they have the same number of neutrons, that is, a constant for the quantity a (atomic number) - z (mass number) a-z. Types of ionizing radiation used in various techniques have different ranges of...

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 ...

What is the lost of some energy from the x-ray beam as it passes through the tissue being imaged? - Beam attenuation The photoelectric affect involves the removal and or ejection of an electron. This process of removing an electron from an atom is? - Ionization When the x-ray photon strikes an atom within the tissue being imaged and looses "all" of it's energy to an "inner" shell electron of an atom the photon is set to have been ________ to undergo ________? - absorb; photoelectric i...
