The anode heel effect is caused by:

A radiographic technique chart recommends 4 milliampere-seconds (mAs) and 68 kilovoltage peak (kVp) at 72 inches for a certain procedure. How will the receptor exposure be affected if the radiograph is performed using the recommended exposure technique but at 60 inches?
