- Which of the following would double the exposure to the IR?
- Doubling the mA
- Doubling the time
- Increasing kVp by 15%
- All of the above
Homework Answers
When the mA is doubled the amount of the radiation is doubles as it is directly proportional, also by increasing the kVp by 15% and doubling the exposure time.
Hence all of the abouve are correct.
Option D is correct.
