questions with precise answers | | |
radiation is defined as - Correct answer ✔a form of energy carried by waves or
| | | | | | | | | | | | | | |
streams of particles | |
a radiograph is defined as - Correct answer ✔a picture on film produced by the
| | | | | | | | | | | | | | |
passage of x-rays through an object or body
| | | | | | |
why are dental images important - Correct answer ✔many dental diseases are
| | | | | | | | | | | |
typically discovered only through the use of dental images
| | | | | | | |
who modified the paralleling technique with the introduction of the long-cone
| | | | | | | | | | |
technique - Correct answer ✔F. Gordon Fitzgerald
| | | | | |
which of the following would you place in the patients mouth in order to take
| | | | | | | | | | | | | | |
dental x-rays - Correct answer ✔image receptor
| | | | | |
the orbiting shell closest to the nucleus has the highest energy level - Correct
| | | | | | | | | | | | | |
answer ✔true |
the binding energy or binding force of an electron is - Correct answer
| | | | | | | | | | | | |
✔determined by the distance between the orbiting electrons and the nucleus
| | | | | | | | | |
, ionization - Correct answer ✔an atom that gains an electron has a negative
| | | | | | | | | | | | |
charge, and an atom that loses an electron has a positive charge
| | | | | | | | | | |
ionizing radiation - Correct answer ✔radiation that is capable of producing ions
| | | | | | | | | | |
|by removing or adding an electron to an atom
| | | | | | | |
Heat is a byproduct of x-ray production. Which component of the x-ray
| | | | | | | | | | | |
tubehead dissipates the heat created by the production of x-rays? - Correct
| | | | | | | | | | | |
answer ✔insulation oil | |
the head collimator - Correct answer ✔restricts the size of the x-ray beam
| | | | | | | | | | | |
which would you adjust if you wanted to create a larger electron cloud - Correct
| | | | | | | | | | | | | | |
answer ✔mA |
in dental radiography, the term .......... is used to describe the mean energy or
| | | | | | | | | | | | | |
penetrating ability of the x-ray beam - Correct answer ✔quality | | | | | | | | |
(1) density is the overall darkness or blackness of a dental image (2) when the
| | | | | | | | | | | | | | |
kilovoltage is increased while other exposure factors rain constant, the resultant
| | | | | | | | | |
image exhibits a decreased density and appears lighter - Correct answer ✔first
| | | | | | | | | | | | |
statement is true; the second statement is false | | | | | | |
mA regulates the ........... of electrons produced at the cathode filament - Correct
| | | | | | | | | | | | |
