Abstract
The hyperconsciousness of radiation dose delivered to the patient during chest radiological X-ray procedures are prerequisite to negate menace of exposure. The pinpoint of this research is to inquest radiation doses received by the patient for routine individual radiological chest x-ray procedures in health care system associated to Kebbi State Government, Nigeria. Entrance Surface Dose and effective dose in accordance with the exposure factors collected for the real examinations were estimated by Cal Dose_X 5.0 software. Diagnostic reference levels [75<sup>th</sup> percentile] and other statistical parameters were calculated by the use of M. S excels spread sheet. The results obtained for ESD in this research work were 2.95mGy, 2.24mGy & 2.25mGy and 1.71mGy, 1.77mGy & 2.55mGy for Chest anteroposterior [AP], posteroanterior [PA] and lateral [LAT] respectively for Sir Yahaya Memorial Hospital (SYMH) and Federal Medical Centre (FMC), Birnin Kebbi. The effective doses were 0.68 mSv, 0.18 mSv& 0.09 mSv and 0.31 mSv, 0.13 mSv & 0.14 mSv for Chest AP, PA & LAT for SYMH and FMC respectively. Similarly, diagnostic reference level for chest AP, PA, & LAT were 2.34, 3.32 & 2.82, and 2.02, 1.88 & 3.19 respectively for SYMH and FMC. The results were compared with national and international studies. The ESD and DRLs reported in this research work for chest examinations were remarkably higher than that of the European Commission (2010), Australia (2017), NRPB (2000), UNSCEAR (2008), Iran (2008) and other research work reported elsewhere. For effective dose, the results were comparatively high except for few research work published in literatures. Therefore, the obtained results in this work revealed that the variations in the results among the two centres and other studies may likely be due to the improper selection of exposure parameters, patientbody sizes, and technical know-how of the staff. Finally, proper selection of radiological parameters and educational training to the staff can significantly reduce the risk of absorbed dose to patients.
