Abstract |
|
|
| The worldwide increase in the use of radiation in diagnostic radiology practice has increased the need for organizations that deal with radiation protection to focus on improving patient protection via the establishment of DRLs. This study was aimed at determining the diagnostic reference level for the pelvis anterior-posterior in some radiological facilities in Abuja metropolis, Nigeria for the establishment of a local diagnostic reference level for Abuja Metropolis. Entrance surface air kerma of 48 mature patients who undertook pelvis anterior-posterior examinations in five centers in Abuja Metropolis, Nigeria using indirect methods were evaluated and used to determine the diagnostic reference level in these centers. The mean values of entrance surface air kerma in each center were 2.39mGy, 2.23mGy, 2.76mGy, 2.75mGy and 3.04mGy with observed variations across different centers and the estimated diagnostic reference level from the five centers included in this study were 2.90mGy, which was found to be lower than the established international reference levels. This implies that radiation risk to average patients in the centers included in this study is low.
