• W4360979551 abstract "Abstract Background The concept of diagnostic reference level (DRL) is considered a regular method to optimize radiation protection in diagnostic imaging system. The objective of implementing a reference level for dose is to produce high-quality images by applying a minimum dose of radiation based on the As Low As Reasonably Achievable (ALARA) principle. Therefore, this study aimed to evaluate the status of radiation protection in diagnostic radiology wards of educational hospitals affiliated with Birjand University of Medical Sciences. Methods This study was performed during a period of 11-months in the radiology center of the teaching hospital of Birjand University of Medical Sciences. The studied population included 477 patients who were referred to as clinically indicated x-ray radiography. In order to calculate local DRLs, dose area product (DAP) was measured by a DAP-meter (KERMAX-plus SPD, model 120–131 HS) for 11 devices at educational hospitals affiliated with Birjand University of Medical Sciences. The local DRL values was calculated as 75% of the mean DAP distribution for a specific patient trial at each center. Results DAP for Chest PA examination was gained to be in the range from 0.12 Gy.cm 2 to 0.42 Gy.cm2 with an average value of 0.23 Gy.cm 2 which is above the value of the reference level (0.12 Gy.cm 2 ) for Chest PA. For Chest lateral the observed DAP was found to be in the range from 0.18 Gy.cm 2 to 1.48 Gy.cm 2 with an average value of 0.65 Gy.cm 2 and are therefore twice the reference value (0.3 Gy.cm 2 ). The higher DRL values (average = 2.73) are for lumbar spine lateral radiography. It is observed that the DRL values of chest PA, abdomen AP and Lumbar spine AP are much lower with the earlier studies. Conclusions The DRLs helps in understanding the current practices in radiographic examinations. Comparison with other hospitals, the scope of dose optimization and ultimately patient dose reduction in hospitals affiliated with Birjand University of Medical Sciences needs further investigation." @default.
