Abstract :
Patient dose measurement is an important tool for dose optimization and patient protection in diagnostic radiology. It is to safeguard both the medical personnel and patient from undesirable effect of radiation. The present study examines the entrance surface Dose (ESD) and effective dose of 101 patients undergoing routine lumbar spine and Lumbosacral joint radiographic examinations in two health care centers consisting two radiological units in Kebbi State north-western part of Nigeria. Patient dose were evaluated using an indirect method [CalDose _X 5.0 software] based on exposure factors. The mean ESD of the results were found to be 4. 83 mGy and 7.46 mGy for lumbar spine respectively for SMH and FMC, while mean ESD for Lumbosacral joints were 5.16 mGy and 8.84 mGy respectively for SMH and FMC. Similarly, the mean estimated ED was 0.47mSv and 0.74 mSv for lumbar spine while 0.39 mSv and 0.55mSv for Lumbosacral joint respectively for SMH and FMC. The results obtained in this study were higher than the doses reported in NRPB 2000, Iran 2015 and ARPNSA, 201 but lower than that of Brazil 2008, and Italy 2005 in some health care centers. Same applied to ED the results obtained were greatly higher than those obtained in literatures. The higher doses obtained can be attributed to the use of higher tube load (mAs) during examinations, which shows lack of optimization of exposure settings.
