Objective: This study aims to establish diagnostic reference levels and radiation-induced risk for the diagnostic CT-scans and the radiotherapy planning CT-scans of the thorax in the regional hospital of Agadir, Morocco. Material and Method: Data from two groups of patients undergoing thoracic CT-scans with either diagnostic CT-scans (G1, n=120) or Radiotherapy planning CT-scans (G2, n=120) are collected. All acquisitions were helical. DRLs is calculated for each type of thoracic CT-scan by estimating the 75% percentile of the CTDIvol and the DLP. The total cancer risk RC was calculated according to the ICRP publication 103. The data are statistically analyzed by SPSS Statistics V21.0. The Pearson’s rank correlation coefficient is chosen to study the relationship between the following parameters: DLP, CTDIvol, effective dose, and the cancer risk. Results: DRLs in terms of CTDIvol and DLP for radiotherapy planning of thorax were 19.37mGy and 851.9 mGy.cm respectively. In diagnostic CT-scans, DRLs in terms of CTDIvol for pulmonary embolism, infectious lung disease,Chronic Obstructive Pulmonary Disease (COPD) were 11.13mGy, 10.26mGy, and 7.37mGy respectively, and DRLs in terms of DLP were 417,73 mGy.cm, 451,9 mGy.cmand 317,78 mGy.cmrespectively. The cancer risk for radiotherapy planning CT-scans is ranged between 209 and 1564 with a mean value of 715 per 1 million of CT-scan. For diagnostic CT-scans, the cancer risk is ranged between 199 and 626 with a mean value of 357 per 1 million for pulmonary embolism, between 238 and 668 with a mean value of 369 per 1 million for infectious lung disease, and between 130 and 393 with a mean value of 244 per 1 million for COPD. Conclusion: Optimizing the doses received by patients in medical imaging, particularly CT, has become an obligation. Reviewing practices and procedures and promoting a radiation protection culture can help to better manage the radiation doses received by the public.

In industrial processes, working on incandescent materials exposes workers to optical radiations that can lead to cataract. In the case where risk cannot be appraised using software simulation, it is necessary to measure visible and near infrared irradiance at the eye of the worker. Since radiometers and spectroradiometers are too expensive for most people in charge of safety at work, a novel method is proposed that assesses irradiance using a photograph taken by smartphone, for example. It consists in summing the irradiance corresponding to each pixel representing the opaque incandescent materials in the picture. Pixel irradiance is assessed from the radiance of the colored body whose temperature and emissivity correspond to the pixel color, weighted by the geometric configuration associated with the pixel in the camera perspective. This virtually free method is accurate enough to assess cataract risk, thereby helping employers to choose an efficient means of protecting workers. In this paper, we present the first principle of the method proposed: temperature and emissivity estimation of incandescent materials. Certains procédés industriels exposent les salariés au risque de cataracte due aux radiations optiques reçues de matériaux portés à incandescence. Si ce risque ne peut être évalué par simulation informatique, l’éclairement dans le visible et le proche infrarouge doit être mesuré au niveau de l’œil du travailleur. Radiomètres et spectroradiomètres étant trop onéreux pour la plupart des préventeurs, une méthode nouvelle est proposée pour évaluer cet éclairement sur la base d’une image du poste de travail, telle que peuvent en fournir les smartphones. La méthode additionne pour tous les pixels associés à une matière incandescente opaque dans l’image, le produit de la luminance d’un corps coloré dont la température et l’émissivité le font correspondre à la couleur du pixel, par le facteur de forme associé au pixel selon la perspective de la caméra. Cette méthode virtuellement gratuite se révèle assez précise pour évaluer le risque et aider l’employeur à prendre les mesures de sécurité adéquates. Cet article présente le premier principe de la méthode : comment estimer la température et l’émissivité des matériaux incandescents.

This study aimed to evaluate the knowledge of radiation dose and associated risks in common diagnostic radiological examinations among radiology staff in comprehensive tertiary hospitals in Wuxi, China. An online questionnaire survey was conducted among radiology staff from seven general tertiary hospitals. The results were compared among different groups, including radiologists, technicians, and nurses. A total of 216 completed questionnaires were collected, with an average accuracy rate of 28.6%. Only 6% of the participants answered more than 50% of the questions correctly. Knowledge regarding the radiation dose for a single-view chest X-ray was known by only 26% of the respondents. Only 8% of the radiology staff demonstrated correct knowledge of managing cases of accidental radiation exposure during unknown pregnancy. The knowledge of radiation dose and its associated carcinogenic risk among radiology staff is inadequate. Underestimation of radiation dose and cancer risk in diagnostic procedures is prevalent, which may lead to suboptimal scanning parameters and potential overuse of radiation in daily practice.

The objective of this study was to evaluate the effective dose and the renal dose delivered to patients during an abdominopelvic examinations, in order to estimate the likely stochastic effects and to judge the need for optimization of CT examination protocols. Data from 287 abdominopelvic examinations of adult patients referred to three Moroccan radiology departments were collected. The mean effective doses, mean renal doses, cancer and hereditary risks assessment were estimated using the weighting factors defined in ICRP 103. During the abdominopelvic CT exam, the effective dose received by the patient varies from 8.99 to 12.09 mSv with an average value of 10.29 mSv, and, the renal dose varies between 5.15 and 8.71 mSv with an average value of 7.56 mSv. The risk of induction of abdominopelvic and kidney cancer ranges from 49.44 to 66.49 and from 28.32 to 47.9 for 105 procedures, respectively. For the hereditary risk of abdominopelvic and renal exposure, it was in the range of 17.98 to 21.86 and 10.3 to 17.42 for 106 procedures, respectively. The results obtained show a wide variation in exposure doses during abdominopelvic CT scans from one hospital to another. Even so, the average effective dose and renal dose was generally lower than that recommended by the ICRP.

Ionizing Radiation is energy in the form of waves or particles and can be absorbed by occupationally exposed professionals (participants). When there is exposure, diseases may occur as defined by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans 2000, then, it is necessary to identify hazards, assess risks and find out experiences of use according to the parties involved, available resources and work processes (Dirk et al., 2014). This research aims to analyze the perception of risk compared to the pillars of radiological protection: Justification/Optimization/Limitation and the principles: Distance/Time/Shielding. The study used qualitative methodology under the phenomenological paradigm, which, based on conversational interviews, allowed an approach to the perception of the participants regarding the risk. The data construction was carried out during the years 2019-2020. The interpretative work was carried out by thematizing interviews, being categorized, and schematized for the analysis process (Morse, 2016). Practices in 5 participants with at least 20 years of experience with the use of radiation were explored. Five categories were identified, and it was found that the principle: ALARA (As-Low-As-Reasonably-Achievable), was recognized based on Distance/Time/Shielding, according to the International Atomic Energy Agency-IAEA (International Atomic Energy Agency, 2007) and Bonn call for action (IAEA & WHO, 2012). The Justification associated with the risk/benefit is not isolated from the fear of being wrong, understanding that 30% of the procedures are not justified (IAEA, 2009).

This study aimed to evaluate the perception of radiation safety culture among medical radiological technologists (MRTs) in the Kingdom of Saudi Arabia. The study was performed from June 2022 to February 2023 and involved MRTs from various hospitals and medical centres in Saudi Arabia. A cross-sectional study was conducted using a self-administered and previously validated radiation safety culture survey instrument in medical imaging departments. The survey comprises 11 determinants of radiation safety culture, including personal accountability, teamwork in imaging, teamwork across imaging stakeholders, questioning attitude, feedback loops, organisational learning, leadership actions, non-punitive response, error reporting, radiation policy and overall perception of radiation safety. A total of 496 MRTs participated in this study. Results showed that most of the MRTs were male (75.0%), between 25 and 44 yr old (71.0%), with a bachelor’s degree (53.2%) and had less than 5 yr of experience (41.1%). The highest mean scores were for personal accountability (4.43 ± 0.62) and teamwork in imaging (4.22 ± 0.91), while the lowest mean score was for non-punitive response (2.94 ± 1.01). The majority of the MRTs reported good perception for the personal accountability (71.8%), teamwork in imaging (56.5%) and organisational learning (46%) scales; moderate perception for the teamwork across imaging stakeholders (53.2%), questioning attitude (71%), feedback loops (47.6%), leadership actions (74.2%), error reporting (53.2%), radiation policy (54.8%) and overall perception of radiation safety (62.1%) scales; and poor perception for the non-punitive response scale (45.2%). Individual and organisational interference are warranted to adhere to a strong radiation safety culture with continuing education. Moreover, repeated measures are necessary to assess for categorical improvement associated with the relevant determinants that are also important to support a positive radiation safety culture.

The study was performed from June 2022 to February 2023 and involved MRTs from various hospitals and medical centres in Saudi Arabia. A cross-sectional study was conducted using a self-administered and previously validated radiation safety culture survey instrument in medical imaging departments. The survey comprises 11 determinants of radiation safety culture, including personal accountability, teamwork in imaging, teamwork across imaging stakeholders, questioning attitude, feedback loops, organisational learning, leadership actions, non-punitive response, error reporting, radiation policy and overall perception of radiation safety. A total of 496 MRTs participated in this study.

Objectifs : Cette étude a pour but d’établir une cartographie territoriale complète et détaillée des salles de radiologie présentes sur un « Groupement Hospitalier de Territoire (GHT) », aussi bien pour la qualité d’image que pour la dosimétrie des radiographies du thorax et de l’ASP. Matériels et méthodes : Sur les différentes installations du GHT, la mesure du kerma dans l’air incident (Ki) et l’évaluation de la qualité d’image à l’aide de l’objet test TOR 18-FG ont été réalisées sur un fantôme de PMMA simulant l’atténuation d’un patient de gabarit standard. Une étude rétrospective complémentaire a également permis d’évaluer la performance clinique des installations. Résultats : L’engagement territorial a permis de recueillir des données pour 23 salles de radiologie au total. Pour la partie dosimétrique, il existe des facteurs 10,3 ; 8,6 et 8,2 entre les valeurs extrêmes des Ki respectivement pour les radiographies « ASP debout » (Abdomen Sans Préparation), « ASP couché » et « Thorax de face ». Concernant la qualité d’image, les disparités observées sont beaucoup plus faibles et semblent plus liées à la technologie de détection. Conclusion : Le travail effectué a permis de mettre en évidence des variations considérables concernant la dosimétrie des radiographies étudiées. Si le paramétrage des protocoles est souvent à l’origine de ces différences, les utilisateurs ont également un rôle majeur dans la radioprotection des patients.
目的：本研究的目的是为 "Groupement Hospitalier de Territoire (GHT) "的放射科病房绘制完整、详细的区域图，以确保图像质量以及胸部 X 射线和 ESR 的剂量测定。材料和方法：在 GHT 的各个设施中，使用 TOR 18-FG 测试对象在模拟标准尺寸病人衰减的 PMMA 模体上测量入射空气热玛（Ki）并评估图像质量。此外，还进行了一项补充性回顾研究，以评估设备的临床性能。结果：通过地区承诺，共收集到 23 个放射室的数据。在剂量测定方面，"站立式 APS"（腹部无准备）、"仰卧式 APS "和 "正面胸廓 "射线照片的 Ki 极值之间的系数分别为 10.3、8.6 和 8.2。在图像质量方面，观察到的差异要小得多，似乎更多地与检测技术有关。结论：已开展的工作显示，所研究的射线照片在剂量测定方面存在相当大的差异。虽然协议设置通常是造成这些差异的原因，但用户在患者辐射防护方面也发挥着重要作用。
