do? - increase the kVp

in taking the radiograph you did not center the beam on the film in the patient's mouth,
the resulting fill will show what? - collimator cutoff

the total filtration of what? - 2.5mm of aluminum

the radiation inspector comes to your office and tells you that your x-ray beam has a
HVL of 1.00mm of aluminum, how will you react? - be concerned because of the
