Abstract |
|
|
| Humans have always been exposed to natural or artificial radiation such as X-rays and gamma rays. Exposure to X-ray radiation is dangerous as it transfers a certain amount of energy to biological system when it interacts with them. Recently, great attention has been paid to monitor and estimate the dose limits of public exposure to X-ray radiation in order to provide an appropriate protection of the public. In this work, the X-ray radiation exposure parameters such as kVp, mAs, FSD, tube output voltage, etc., were recorded for chest, skull, abdomen, pelvic, lumbosacral and cervical spine X-ray procedures of fifty (50) male and female patients underwent X-ray examination in University of Maiduguri Teaching Hospital (UMTH). The recorded parameters for chest antero-posterior (AP), postero-anterior (PA) and lateral (LAT), abdomen AP/PA, skull AP/PA/LAT, cervical spine AP/LAT lumbosacral spine AP/PA/LAT and pelvic AP X-rays examinations were converted to entrance surface dose (ESD). The mean ESD values measured for patients undergoing X-ray examination in UMTH using a conventional X-ray machine, ranges from 0.2261 mGy for cervical spine LAT to 2.6865 mGy for lumbasacral spine LAT for female patient and ranges from 0.372 mGy for abdomen PA to 2.0436 mGy for lumbosacral spine PA for male patient. These ranges of ESD values were much lower compare to guidance levels set by international radiation protection bodies. Thus, there is no any significant health risk to the female and male patient underwent X-ray procedures in UMTH. Such ESD assessment is essential to prevent health risks of X-ray exposures during the radiological procedures. |
