Question Number: 399 Detection and Measurement In NTE (nuclear track emulsion) film, the tracks are caused by: A) alpha particles. B) beta particles. C) gamma photons. D) recoil neutrons. E) recoil protons. correct answers The correct answer is: E In this fast neutron responsive dosimeter, recoil protons from elastic scattering with hydrogen atoms in the film create short "tracks" of ionization as stable silver atoms are created. These tracks are counted either by eye or mechanica...

Occurs only at doses used in radiation therapy B. Describes changes in the x-ray beam as it travels through the patient Which photon-tissue interaction makes radiography possible because of its creation of contrast? A. Compton B. Coherent C. Photoelectric D. Pair production C. Photoelectric Which photon-t...

TEAS Test Science Questions ACTUAL EXAM QUESTIONS AND CORRECT DETAILED ANSWERS WITH RATIONALES (VERIFIED ANSWERS) |ALREADY GRADED A+ A specific isotope has an atomic number of 51 and a mass number of 122. How many electrons are contained in the neutral atom? a. 51 b. 71 c. 122 d. 173 - CORRECT ANSWER A: The mass number is the sum of the number of protons and neutrons. The atomic number is the number of protons, which is always equal to the number of electrons in a neural atom. ...

What is the most important law applicable to the study of electricity? CORRECT ANSWER Ohm's Law (I = E ÷R) What are the elements of Ohm's Law? CORRECT ANSWER Voltage (E), current (I), and resistance (R) What are the sources of electrical power? CORRECT ANSWER Mechanical (generator), chemical (battery), photoelectric (light), and thermal (heat) What does an electrical circuit consist of? CORRECT ANSWER A source of electrical pressure or EMF, resistance in the form of an energy consumi...

what mag modes are available? - correct answer if you have a 16" II, you can have 12,9,6, and 4.5 " Compton effect - correct answer hits the outer electron, incomplete transfer of energy, electron released and a low energy xray is deflected photoelectric absorption - correct 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 charac...
