DAP (Dose Area Product) is a quantity used in assessing the radiation risk from
diagnostic X-ray examination procedures. It is defined as the absorbed dose multiplied
by the area irradiated, expressed in gray square centimeters (mGy·cm 2 ). Despite the
limitation, DAP is the best way to predict effective dose value and is currently the most
convenient method for patient dose monitoring.
