“…Several cases raise the level of radiation knowledge in staff, patients, and physicians. Continuous beam training increases radiation safety and reduces fear of radiation [19,35,36], as well as determining radiation levels and dose level references for each region [12] and monitoring personnel radiation measures are two other effective strategies [34]. In our study, it was clearly demonstrated that the dose received in nuclear medicine tests (more than 500 times that of Chest PA) increased the risk of cancer in younger people, especially in vulnerable tissues.…”

“…An overall review of the previous study, indicates that radiologists and technologists who are employed in different sections have inadequate information about ionizing beams, or they underestimate its harms [11 − 8]. All the same, another study claims that reducing the dose level in X-Ray examinations is possible if imaging center staff get appropriate training [12]. Nowadays, by spreading information, clienteles of imaging centers inquire about potential perils of "imaging procedures."…”

Background Identifying the level of radiology students and radiologist's awareness about their knowledge of radiation risks and radiation protection and their understanding of radiation dose levels in medical imaging tests will help global and national lawmakers adjust laws according to the recognized need in studies. The significance of this study is further enhanced when it is considered a lack of radiation awareness may increase the risk of radiation damage to themselves and patients. Method: This Crossectional study is done on 180 people, including 62 people were students (radiology residents and technologists), and 118 people were radiology staff (radiologists and radiographers). For measuring the awareness of participants, a prepared questionnaire which had a total of 22 questions. The poll was divided into three sections of which: Demographics data, Radiation protection awareness, and knowledge of radiologists about dose assessment. The questionnaire reliability was assessed in terms of internal consistency utilizing the Cronbach’s alpha (0.85_). A P-value of less than 0.05 was set a threshold for statistical sig-nuisance. Statistical analysis was carried out using software SPSS version 22. Result Most students believed that 1-year-old girls had the most sensitivity to radiation, while most staff found that radiation risk was unrelated to age and sex. Both staff and students found that crews working in nuclear medicine departments were more exposed to radiation (the majority). Most students and faculty also chose breast tissue as the most sensitive organ against radiation. It should be noted that among the staff responses, a significant number of bones were also selected. In general, students and staff did not have sufficient information about radiation-related illnesses. Approximately 82 percent of students chose a dose of Lumbar X-ray exams between 1 and 50 times the PA chest, and only 9 percent answered the question correctly (100 − 50 times). However, 27% of employees chose the correct answer. Students on the average dose of mammography had more choice (1–10 times) of a PA chest test, while staff preferred 100–500. (Both groups did not perform well in this question). The crew performed better on the dose resulting from a PET-CT test as well as the dose estimate from a nuclear medicine heart scan, and selected 36% correct response (more than 500 times the PA chest), while students had a lower rating (1–10 times) than others. Conclusion Most students and staff believed that they had a suitable or sufficient level of awareness of ionizing radiation. Overall, 45% of students and staff rarely had any training or retraining (37%). Radiology students had a better level of knowledge about radiation protection than team, while team had better estimates in discussing dose assessment. In general, students and staff did not have sufficient information about radiation-related illnesses. Students and staff had accurate estimates of the dose received in a PA chest and the average dose of background radiation. Both groups had little information on mammography, but had good knowledge of ultrasound, MRI, and CT scans. In general, staff and students had a good understanding of nuclear medicine dose assessment. (Staff performed better)

BACKGROUND: Evaluation of radiographic equipment performance is the recommended strategy for the verification of factors used in radiodiagnosis. Sometimes, the performance of the equipment is compromised due to the lack of adoption of the appropriate procedures and/or techniques. AIM: The aim of this study was to determine the performance quality of the radiographic equipment in the study area in order to optimize the radiation dose delivered to the patients using these facilities and enhance their safety. METHODS: The performance characteristic of selected radiographic equipment was determined using MagicMax quality control kits and test object. Radiographic equipment in eight selected radiodiagnostic centers designated as C1-C8 was assessed. RESULTS: The results showed that all the radiography units in the studied centers passed the kVp reproducibility and mAs linearity tests with the exception of center C2. The kVp deviation for the centers varied between 2.0 and 7.7%, with the highest deviation in center C5 and lowest value in center C6. Center C7 has the highest deviation (–13%) of mAs, while the lowest value was obtained in center C6 (0%). The dose was lowest in center C1 and highest in center C3. The half-value layer, mAs, and filtration values had a stronger correlation with the incident air kerma dose compared to the other parameters. In addition, 50% of the equipment passed all the performance tests. CONCLUSION: The study revealed that the performance characteristics of radiographic equipment in the studied area require improvement. Periodic monitoring of the equipment performance is recommended for adoption and enforcement to enhance quality practices and radiation safety.
