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 currently the most convenient method for
patient doses monitoring.

PHE (Public Health England) recommends that any national reference dose that
achievable dose (DAP) value of 250 [mGy·cm2] for a clinical protocol for a standard
male patient.
