BMET 110 QUESTIONS WITH ACCURATE ANSWERS
'Fixed' intraoral x-ray system correct answer anchored to a wall
'Mobile' intraoral x-ray system correct answer mounted on a pedestal on wheels
and used when a patient cannot be readily moved to an x-ray room
6-pulse formula correct answer kVp x mA x time x '1.35' = H.U.
12-pulse formula correct answer kVp x mA x time x '1.44' = H.U
ALARA correct answer As Low As Reasonably Achievable
alpha particle correct answer consists of two protons and two neutrons tightly
bound together
alpha particles correct answer considered a devastating internal hazard
angulation scales correct answer placed on the sides of tube head
artifact correct answer a blemish appearing on a digital image that looks like it
was created by he object but in fact was created by the process which can
interfere with the visualization of anatomical structures and can lead to
misdiagnoses
autotransformer correct answer allows adjustment of incoming line voltage
, beta particals correct answer (travel at speeds between 100,000 to 186,000 miles
per second) considered an external hazard because they can penetrate up to 1 to
2 centimeters of human flesh
beta particle correct answer high energy, high speed electrons that are ejected
from the nucleus by some radionuclides during a form of radioactive decay
