Abstract |
|
|
| Medical X-ray imaging is extensively used in Nigeria making the practice the most significant source of medical exposure from ionizing radiation compared to therapeutic components. This study is aim at estimating the diagnostic reference level for chest posterior-anterior in some radiological facilities in Abuja metropolis, Nigeria. A total of 265 patients from the six selected centres undertook chest X- ray examination. Entrance surface air kerma was evaluated by indirect method. The peak tube potential, tube loading, focus to film distance, X-ray machine output and the back scattered factor were determined. The mean values of entrance surface air kerma and diagnostic reference level are 0.67mGy and 0.64mGy respectively. The entrance surface air kerma and diagnostic reference level is slightly higher than the international reference levels. This implies that there could be risk to patients that underwent X- ray examination in the centres. It is recommended that there is need to develop standard operating protocol for different X-ray examination procedures. |
