“…Our findings are in agreement with findings of the studies conducted by Egbe et al [8] , Ogundere et al [9] , Mooney and Thomas [10] , which were higher than the recommended values. This could be due to scatter contribution at the exit point, collimator scatter effects, and flattering filter scatter effect.…”

“…[3] The normal values for (ESD) for < 1 year, 1-5 years and 6-10 years are: 0.02mGy, 0.03mGy and 0.04mGy ESD (mGy) Vol.6; Issue: 4; October-December 2021 respectively. The higher values of ESD documented in this study is also in line with previous studies conducted by Egbe et al [8] , Ogundere et al [9] , Mooney and Thomas [10] and Zewdu et al [11] though with some discrepancies in their findings. Egbe et al [8] in their studies, reported ESD from three different hospitals in Nigeria as follows: University of Calabar Teaching Hospital (UCTH) as: 0.64 ± 0.15mGy, 1.82 ± 1.17mGy, and 1.70 ± 1.04mGy for < 1 year, 1-5 years and 6-10 years respectively.…”

Background: Radiation protection in paediatric radiology deserves special attention as children are supposed to be more sensitive to radiation than adults. Aim: This study was designed to evaluate the radiation doses for paediatric patients undergoing diagnostic chest X-ray examination. Materials and Methods: This was a cross-sectional survey, which targeted paediatric patients of (0-10) years who were referred by their physicians for chest X-rays examination. The data used for this work were generated using a Thermoluminescence dosimeter (TLD) chip. One TLD chips was placed in the front of the chest to measure the Entrance Surface Dose (ESD) (µGy) and another at the back of the patient directly opposite the one in front to measure the Exit Dose (ED) (µGy). Patient dose, age, ESD, ED and absorbed dose were obtained. The obtained data were analyzed using descriptive statistics. Results: The mean ESD, ED and absorbed dose values were 1.8330± 1.122mGy, 1.0913± 0.7505mGy and 0.7520 ± 3.8160mGy respectively. The ED values in chest X-rays were 0.73± 0.30mGy for age group <1 year, 1.15± 0.91mGy for age group 1-5 years and 6-10 years 1.09± 0.75mGy. The ESD were 3.06 ± 1.76mGy for age group <1, 3.02± 2.04mGy for age group 1-5 years and 6-10 years 1.83± 1.12mGy. The absorbed dose values obtained were 1.88± 1.75mGy for age group <1 year, 1.88± 1.67mGy for age group 1-5 years and 0.75± 3.82mGy for age group 6-10 year. Conclusion: The values for Exit Dose, Entrance Surface Doses, and Absorbed Dose have been determined and it was found to be slightly higher than UNSCEAR values.

“…The mediastinal, retrocardial and spinal area (as seen through the heart) of the chest images recorded the highest marging in the image quality criteria. This agrees with the result of Egbe et al, (2009). The image score obtained in this study may be due to the fact that both majority of the patients were of average to below average size and the use of Radiographers in imaging procedures.…”

“…Radiation dose to patients from diagnostic x-ray machine assures a simple functional dependence on radiographic exposure parameters of kVp, mAs, SSD, filtration and thickness [8,9] . Monitoring of patients during the examination has been a major way of assessing radiation dose received in diagnostic and therapeutic radiography [10]. For the purpose of optimization in radiation protection, dose delivered to patients during diagnosis is studied with assessment of image quality [12,13] .…”
