Based on the results of this study, ESD and ED were calculated for skull (PA), skull (lateral), cervical spine (AP), cervical spine (lateral), chest (PA), chest (lateral), abdomen (AP), lumbar spine (AP), lumbar spine (lateral), pelvis (AP), thoracic spine (AP) and thoracic spine (lateral) examinations. It was calculated using PCXMC software (version 2.0).Results: In this study, mean ESDs for the 10-15 year group varied from 0.97±0.21 mGy to 3.62±1.38 mGy for chest (PA) and lumbar spine (lateral), respectively. For the adult group varied from 1.05±0.31 to 3.85±1.44 for cervical spine (AP) and lumbar spine (lateral), respectively.

Application of a dose reference level (DRL) could be an optimization procedure for reducing the patient’s dose in Mazandaran province.</abstract>
