Introduction: Medical uses of radiation have grown very rapidly over in the past two decades, medical uses represent the largest source of exposure to people, The most important methods in medical diagnosis are the useses of diagnostic radiology exams. Although the use of these methods is very beneficial for the treatment of patients, but ionizing radiation produces ion pairs, radicals, primary, secondary, and tertiary chemical reactions in body. The main purposes of this study were to investigate patient dose in common radiographic examinations
Materials and Methods: This study was performed in radiology centers and hospitals affiliated with Jiroft University of Medical Sciences, including Qaleh Ganj Hospital, Imam Khomeini Hospital, Kashani Hospital and 12th Farvardin Kahnoch Hospital. In each center, measurements are performed on at least 10 patients aged between 25 - 60 years for different imaging techniques including: Chest (PA), Pelvic (AP), Abdomen (AP), Skull (AP) and (LAT), Lumbar Spine (AP) and, Lumbar Spine (LAT) .ESD, ED were measured with T-LD 100 and PCXMC software, respectively
Results: The average entrance skin dose (mGy) and effective dose (mSv) for the Chest (PA), Abdomen (AP), Pelvice (AP), Lumbar Spine (AP) and Lumbar Spine (LAT) and Skull (AP) and Skull (LAT) were (0.63-0.06), (2.34-0.32), (2.48-0.39), (3.33-0.34), (7.32-0.17), (2.9-0.02)
and (1.81-0.01) respectively.
Conclusion: The values indicate that the implementation of quality control and quality assurance programs in the radiology centers is necessary and all radiographic exams should be performed under lower doses with best quality of image.
