Question 1 of 15What does ALARA stand for?
Show answer

Answer: As Low As Reasonably Achievable. ALARA means keeping dose as low as reasonably achievable.

Question 2 of 15Which exposure factor mainly controls beam penetration?
Show answer

Answer: kVp. kVp controls the penetrating power of the beam.

Question 3 of 15In a PA chest projection, the patient faces:
Show answer

Answer: The image receptor. For a PA view, the beam enters the back and the patient faces the receptor.

Question 4 of 15A dosimeter measures:
Show answer

Answer: Radiation exposure to the wearer. Dosimeters track occupational radiation exposure.

Question 5 of 15Collimation helps by:
Show answer

Answer: Limiting the beam to the area of interest. Tight collimation reduces dose and scatter.
