GXMO OHIO |UPDATED |REAL EXAM
2025/ 2026 QUESTIONS WITH
VERIFIED ANSWERS
1. Image Inversion - correct answer -A post processing
technique where the bone appears black and tissue appears
white.
2. Image Receptor - correct answer -The device that
transforms the x-ray beam into a visible image; radiographic
film or a phosphorescent screen
3. Incident Radiation - correct answer -The radiation beam prior
to hitting the patient
4. Indirect conversion - correct answer -The x-ray energy is
converted into light by means of a scintillator, then converted
into an electrical signal by means of a photodiode
,5. Indirect effect - correct answer -When the x-ray photon
causes water to break down forming free radicals which
damages DNA
6. Intesifying screens - correct answer -sensitive phosphor that
converts x-rays exposure time and reduce patient dose
7. Inverse Square law - correct answer -Law that states that the
intensity of radiation at a location is inversely proportional to
the square of its distance from the source of radiation.
8. Inverse square law formula - correct answer -I1/I2 =
D2^2/D1^2
9. Ion - correct answer -atom with too many or too few
electrons; an electrically charged particle
10. Ion pair - correct answer -Two oppositely charged
particles
, 11. ionization - correct answer -removal of an orbital
electron from an atom
12. ionization chamber - correct answer -Instrument that
detects and measures the radiation intensity in areas outside
of protective barriers
13. ionizing radiation - correct answer -radiation capable of
ionization; produces positively and negatively charged
particles when passing through the body
14. isotropic - correct answer -equal intensity in all
directions; have the same properties in all directions
15. Kilovolt Peak (kVp) - correct answer -Measure of the
maximum electrical potential across an x-ray tube; x-ray
quality; penetrating ability of x-rays
