“…This also shows that variations of ESD can be associated with the exposure parameters in X-ray machines. The different technology and technological parameters of an X-ray system may be responsible for such modifications of ESD [21,22]. The measurement variation may also be due to the application for each machine with various filtering and HVL thicknesses.…”

This study aims to compare entrance surface dose (ESD) values measured with nanoDot Al 2 O 3 :C optically-stimulated luminescence dosimeter (OSLD) and guidance level set under the second national dose survey which utilized old-version LiF:Mg,Ti thermoluminescence dosimeter (TLD). In this study, we conducted a dosimetric assessment for posteroanterior chest X-ray (PA-CXR) examinations performed at various community clinics in Perak, Malaysia. These clinics were selected as they were excluded from the first and second national dose survey conducted in Malaysia in 1993-1995 and 2005-2009, respectively. The ESD is obtained by mounting the OSLD on the surface of polymethyl methacrylate (PMMA) slabs. The PMMA slabs were then exposed to X-ray based on the current practice of respective clinics. The results show that the 3 rd quartile of ESDs ranged from 0.180 mGy to 0.229 mGy which is less than the recommended guidance level of the second national dose survey by 77 %. ESD measured using OSLD was found to be lower than the guidance values recommended from the second national dose survey. The finding showed a good competency of the radiographer to optimize radiological practice specifically in routine X-ray examination.

“…Moussa and Kamoun led a study on workers' knowledge of radiation protection at the CHU Mongi Slim in La Marsa in Tunisia. They reported that the wearing of dosimeters was not respected by 70% of the staff due to the non-existence of this work equipment (Muhogora and Rehani, 2017). The absence of an individual dosimeter is a failure due to the absence of a radiation safety authority or control body.…”

Poor compliance with standard radiation protection procedures induces risk to the safety and the health of the population and the medical staff. This study aims to assess compliance with standard radiation protection processes in medical imaging (MI) units in the Atlantique and Littoral departments of Benin in 2019. This was a cross-sectional, descriptive, evaluative study led from March to April 2019 in the functional MI divisions of hospitals in the Atlantique and Littoral departments. Imaging technicians or handlers were included for convenience and the managers of medical imaging units by reasoned choice. The compliance with standard radiation protection processes in MI units (main component) was assessed by assigning an overall score resulting from the appreciation of the subcomponents (radiation protection means, radiation protection processes, the working environment, and the knowledge of the staff). There were 89 respondents in 18 MI units included in the study. The mean age of the staff was 36.5 ± 9.5 years, with a male domination of 56.34%. Compliance with standard radiation protection processes was low, with an overall score of 41.41%, mainly due to a weakness in the sub-components "Radiation protection means", "Radiation protection processes", "Working environment" and "Handler knowledge", which scores were of 33.01, 44.24 and 11.67%, respectively. Only the sub-component related to technicians was medium, with a score of 60.50%. The implementation of radiation protection measures in the medical imaging units of the Atlantique and Littoral departments in Benin is insufficient. The establishment of a regulatory and nuclear safety authority could help to meet the challenge of radiation protection in Benin's imaging units.

“…The data was collected by using self-administered questionnaire and document review. The questionnaire was comprised from socio-demographic and economic, personal, occupational, institutional and environmental factors based on ERPA guidelines, ICRP recommendations, and different literatures [ 10 , 15 , 16 , 22 , 24 ] to address all important variables which affect occupational radiation exposure dose. The data of the respondents was collected utilizing a Google form, which is an electronic-based data collection approach.…”

“…However, for a variety of reasons, the amount of occupational radiation exposure dosage is higher in developing countries. Perhaps the most important reasons are a lack of skill and experience, a lack of radiation protection education and training, a lack of radiation protective barriers, poor machine quality (the machines are either old, conventional machines or donated used machines), a lack of equipment calibration, and a lack of machine spare parts [ 10 , 11 , 15 , 16 ].…”

Background Ionizing radiation is being used more frequently in medicine, which has been linked to recognized biological effects such as cancer and mortality. Radiology services are becoming more widely available in Ethiopian health facilities but there is no compiled record of worker’s radiation dose. So, assessing the magnitude and identifying the associated factors of occupational radiation exposure dose among radiology personnel help to design strategies for radiation protection. Objective The study was designed to assess the occupational radiation exposure dose and associated factors among radiology personnel in eastern Amhara, northeast Ethiopia, 2021. Methods Cross-sectional study was conducted from March 25 to April 30, 2021, in 57 health institutions among 198 radiology personnel. The study comprised all eligible radiology personnel. The data were collected using an electronic-based (Google form) self-administered questionnaire, and document review. The data were entered into an excel spread sheet and then, exported to Stata 14 software. Linear regression model was used to analyse the data after checking its assumptions. Variables with a p-value < 0.25 were entered into a multiple linear regression analysis, and those with a p-value < 0.05 were judged significant. VIF was used to check for multi-collinearity. Coefficient of determination was used to check the model fitness. Results The mean (± SD) annual shallow and deep dose equivalents of radiology personnel were 1.20 (± 0.75) and 1.02 (± 0.70) mSv, respectively. Body mass index (β = 0.104, 95% CI: 0.07, 0.14), practice of timing (β = -0.43, 95% CI: -0.73, -0.13), working experience (β = -0.04, 95% CI: -0.048, -0.032), and practice of distancing (β = -0.26, 95% CI: -0.49, -0.17) were found to be statistically significant factors of annual deep dose equivalent. In addition, body mass index (β = 0.113, 95% CI: 0.08, 0.15), practice of timing (β = -0.62 95% CI: -0.93, -0.31) and, working experience (β = -0.044, 95% CI: -0.053, -0.036 had statistically significant associations with annual shallow dose equivalent. Conclusion The annual dose equivalents were two times higher than the global average of annual per caput effective dose due to medical exposure. Body mass index, practice of timing, working experience, and practice of distancing were factors of occupational radiation exposure dose. Strategies focusing on increasing the skill, experience, and lifestyle of radiology personnel would be supreme important means to reduce occupational radiation exposure dose.
