Background: The ionizing radiation has an indispensable role
in #diagnostic radiology and #clinical treatments. Apparently, medical
exposure in diagnostic radiology pertains to be the preeminent man-made
source of radiation.
Objective: The nobility of the present scientific study was to
establish a precise #national diagnostic reference levels (NDRLs) in
digital radiography in Iran.
Methods: Conceptually, 15358 patients participated in 85 X-ray
rooms and the data was obtained from five different age groups: 0>1
year, 1>5 years, 5>10 years, 10>15 years. And eventually in
adults in each projection. The #dosimetry protocol was indirect for
measuring Entrance Surface Air Kerma (ESAK).
Results: The national diagnostic reference level was settled
for Skull (PA), Skull (Lat), Cervical spine (AP), Cervical spine (Lat),
Chest (PA), Chest (Lat), Abdomen (AP), Lumbar spine (AP), Lumbar spine
(Lat), Pelvis (AP), #Thoracic spine (AP), and Thoracic spine (Lat).
Conclusion: A wide variations of radiation dose for x-ray
examinations among hospitals in Iran was proceeded; furthermore, it was
magnificently attained that the DRL for adult chest (PA) examination
could be higher than European countries and Turkey; because of the high
exposure parameters could be applied.
