The exposure factors used at an oral health care facility are 10 mA, 0.9 sec, 70 kV, and 16 inch (41 cm) target image receptor distance. A radiographer increases the mA to 15, but leaves the kV and target-image receptor distance constant. To maintain identical image density, what should be the new exposure time?

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