The exposure factors used at an oral health care facility are: 10 mA, 0.9 sec, 70 kVp, and 16 in target-image receptor distance. The radiographer increases the mA to 15, but leaves the kVp and the target-image receptor distance constant. To maintain identical image density, what should the new exposure time be?

A radiographer stands 4 ft from the head of the patient while exposing a dental radiograph. Her personnel monitoring device measures the radiation dose at that position to be 0.04 mSv. The radiographer decides to move to a new location 8 ft from the head of the patient. What is the dose at the new location?

A patient presents whose radiographs must be taken utilizing the bisecting technique. The radiographer decides to replace the 16 in PID with an 8 in PID to better accommodate the bisecting technique. Currently the impulse setting with a 16 in PID is 12. To maintain image density, what will the new impulse setting be with the 8 in PID?
