There are three cardinal are cardinal principles of radiation protection: time, distance, and shielding (TDS) Related to the time reduction the responsibility of the radiographer is except?
- A.
Reduce the amount of time of exposition
- B.
Reduce the amount of time that the patient is exposed to radiation
- C.
Use fast exposure-time factor whenever possible
- D.
Use slow exposure-time factor whenever possible
Correct Answer
D. Use slow exposure-time factor whenever possibleExplanation
The correct answer is to use fast exposure-time factor whenever possible. This is because reducing the exposure time helps to minimize the amount of radiation that the patient is exposed to. Using a fast exposure-time factor allows for a shorter duration of radiation exposure, thus reducing the potential harm to the patient. On the other hand, using a slow exposure-time factor would prolong the exposure time and increase the amount of radiation the patient receives, which goes against the principle of time reduction in radiation protection.Rate this question:
