Nuclear medicine (NM) is an essential radiology department in healthcare facilities. In NM procedures, radioactive isotopes are administered intravenously or orally to assess the molecular, metabolic, physiologic, anatomical and pathologic states of the body for diagnostic therapy and research applications. The personal radiation dose data of 269 NM technologists and 132 nurses, all with annual dose records, from 2016 to 2021 are collected in four major medical centres. Personal radiation doses in NM departments are monitored on a quarterly basis using thermoluminescent dosimeters (TLDs). The TLDs used have an approximate tissue equivalence of 8.14 and a density of around 2.64 g cm3. TLDs are read using WinREMS software and a Harshaw 6600 plus reader. In this study, only Hp (10), which estimates the effective dose, is included in the analysis. The result showed that the NMTs and nurses’ overall mean effective dose during the study period were 1.06±0.60 mSv (0.063.26 mSv) and 0.92±0.70 mSv (0.015.52 mSv), respectively. The result of our study found lower values of annual mean effective doses compared to previous studies conducted in Saudi Arabia. The mean effective dose among both workers were below the permissible dose limits, which suggest a safe work environment in term of radiation protection practices.
核医学(NM)是医疗机构必不可少的放射科。在纳米技术中，放射性同位素通过静脉注射或口服来评估人体的分子、代谢、生理、解剖和病理状态，用于诊断治疗和研究应用。收集了2016年至2021年四个主要医疗中心269名纳米技术人员和132名护士的个人辐射剂量数据，均有年度剂量记录。每季度使用热释光剂量计监测NM部门的个人辐射剂量。所使用的tld具有近似的组织等效性8.14，密度约为2.64 g cm−3。使用WinREMS软件和Harshaw 6600 plus阅读器读取顶级域名。在本研究中，只有估算有效剂量的Hp(10)被纳入分析。结果显示，研究期间nmt和护士的总体平均有效剂量分别为1.06±0.60 mSv(0.06±3.26 mSv)和0.92±0.70 mSv(0.01±5.52 mSv)。我们的研究结果发现，与先前在沙特阿拉伯进行的研究相比，年平均有效剂量值较低。这两名工人的平均有效剂量均低于允许的剂量限值，这表明就辐射防护措施而言，工作环境是安全的。

The purpose of this study was to evaluate radiation doses during Computer Tomography (CT) scans of the whole body and organs using a fabricated phantom. The Weighted Computer Tomography Dose Index (CTDIw) was evaluated and measured using a fabricated phantom, and five CT scanners were used for chest examinations from four hospitals in Najran, Saudi Arabia. The heart, lungs, esophagus, and spinal cord doses were measured with clinical whole body CT acquisition protocol using Thermoluminescent Dosimeters (TLDs). The TLDs used for measurements were selected for an accuracy of 5% and calibrated for the X-ray radiation field. The CTDIw and organ doses reported in this study were compared with results of ImPACT software for calculating organ doses. The results show good agreement with the calculations and the literature. The measured specific organ doses ranged between 1.33 mGy (Lung marrow) and 1.65 mGy (Esophagus). The model is easy to produce and useful for evaluating the organ doses and CTDIw.

Informal volunteerism in its various forms is on the rise in the safety and security arena. This study focuses on a new mode of informal volunteerism, virtual volunteerism. The study uses the complex context of a nuclear emergency to explore (1) the extent to which informal volunteerism, in the form of virtual volunteerism, can develop information resilience and (2) the problems and challenges involved. The study relies on interview data gathered from 18 Finnish public authorities and NGO actors working in expert or managerial positions connected to nuclear emergency response. The study results suggest that informal virtual volunteerism could play a role in the development of information resilience in society. However, as suggested in previous studies, virtual volunteerism could be a double-edged sword. There is a real risk of mis- and disinformation because of the volatile times in which we live. The identified risk sparked a debate on the inclusion and exclusion of unaffiliated disaster knowledge workers and virtual emergent groups in nuclear emergency preparedness, response, and recovery.

Radiation protection is among the important issues in the wards exposed to radiation. Considering the daily increasing use of radiation in operating rooms and the existing problems in the field of radiation protection, the present study aimed to evaluate the clinical capability of operating room nurses and surgeons regarding radiation protection protocols in radiation-exposed operating rooms in Shiraz. Methods: This descriptive, cross-sectional study was conducted through census on radiation-exposed nurses and surgeons in operating rooms of private and public hospitals in Shiraz in 2019-2020. The study data were collected using a demographic and professional information form and a questionnaire on radiation protection capability of operating room personnel. Then, the data were entered into the SPSS 25 software and were analyzed via descriptive and inferential statistics. Results: Totally, 200 questionnaires were completely filled out. The mean age of the participants with complete questionnaires was 33.34+8.09 years. The mean scores of clinical capability, knowledge, attitude, performance, and personal commitment were 111.7+21.09, 39.05+12.76, 44.25+7.16, 14.61+6.23, and 13.98+5.77, respectively. Accordingly, the participants’ knowledge, attitude, personal commitment, and clinical capability were at good levels, while they showed a weak performance. Conclusion: It seems that educational as well as managerial measures in terms of radiation protection protocols are needed to increase the clinical capability of radiation-exposed operating room nurses and surgeons. The present study results can be used to improve clinical capability regarding radiation protection, provide related strategies, and solve problems.

As the use of chest CT examination during the COVID-19 outbreak is increased, patient radiation doses are become a concern. So, this survey was conducted to evaluate the patient radiation dose and estimated the cancer risk of chest CT examination during COVID-19 outbreak. From February 2020 to September 2021, 165 Chest CT examination were acquired. For all patients we have examined organ doses and the effective dose using ImpactDose software. The risk of exposure-induced death (REID) values was estimated by using models developed in the BEIR VII (Biological Effects of Ionizing Radiation VII)-Phase 2 report. Study population included 165 patients, 75 male and 90 female, with an average age of 51 years. The mean effective dose in females were greater than in the males (5.42 vs 4.43 mSv, p ˂ 0.0001). The mean REID values in patients undergoing chest CT examination with a 16-MDCT scanner were 232 per million male and 351.3 per million female. The risk of lung cancer was high for both male and female. According to our study, it is proposed that to use low-dose CT chest protocol, as a reliable tool in detecting COVID-19 pneumonia in daily practice, can reduce radiation dose and estimated cancer risk.
随着新冠肺炎疫情期间胸部CT检查的使用增加，患者的辐射剂量成为人们关注的问题。因此，本调查旨在评估COVID-19暴发期间患者的辐射剂量，并评估胸部CT检查的癌症风险。2020年2月至2021年9月，165例胸部CT检查。对于所有患者，我们使用ImpactDose软件检查了器官剂量和有效剂量。使用BEIR VII(电离辐射生物效应VII)第2阶段报告中开发的模型估计了暴露诱发死亡(REID)值的风险。研究人群包括165例患者，其中男性75例，女性90例，平均年龄51岁。女性的平均有效剂量大于男性(5.42 vs 4.43 mSv, p小于0.0001)。接受16-MDCT胸部CT检查的患者的平均REID值为男性232 /百万，女性351.3 /百万。男性和女性患肺癌的风险都很高。根据我们的研究，建议在日常实践中使用低剂量CT胸部方案作为检测COVID-19肺炎的可靠工具，可以降低辐射剂量并估计癌症风险。

Objectif : analyser les évènements nucléaires survenus chez les professionnels, dans les services des hôpitaux publics de référence utilisant les rayonnements ionisants. Matériels et méthodes :Étude rétrospective à visée descriptive, sur une période de 11 ans allant de Décembre 2010 à Juillet 2020, dans les services d’imagerie médicale et de radiodiagnostic des hôpitaux publics de référence. Nous avons recensé tous les accidents et incidents nucléaires enregistrés par les services de santé au travail, décrits leurs circonstances de survenue et définit leur sévérité selon l'échelle internationale des événements nucléaires et radiologiques (INES). Résultats : nous avons relevé 3 évènements nucléaires, soit un taux d’incidence annuel de 0,3‰. Ils étaient tous classés incidents selon l’échelle INES dont 2 cas de niveau 2 et un cas de niveau 3. Les circonstances de survenue étaient, accidentelles pour 2 cas et en rapport avec une faute professionnelle pour le troisième. Ils sont survenus exclusivement chez des manipulateurs de radiologie. Aucun évènement nucléaire n’était rapporté chez les médecins radiologues et les autres professionnels travaillants à proximité des sources de rayonnements ionisants. Il n’y a pas eu d’accident nucléaire. Une éviction définitive des postes de travail sous rayonnement a été décidée pour l’incident de niveau 3. Conclusion : Les événements nucléaires chez les professionnels de la santé étaient rares, de faible gravité et concernaient exclusivement les manipulateurs en radiologie. Le facteur humain en était la cause.

The image-based cargo inspection systems are generally intended to identify illegal practices. However, imaging processes from the scanning of motorized containers have been used for increasing industrial safety. This is made possible by the application of high energy particle linear accelerators (linac). Measurements of both the environmental equivalent dose rate (δH*(10), and the integrated environmental equivalent dose (H*(10) were performed. The estimation of δH*(10) and H*(10) in the scanning channel, including the driver's cab of the truck transporting the container, is critical. The aim of this study is to check the radiological safety for occasional users (drivers) by comparing the levels of δH*(10) and H*(10) with those adopted for public exposure. The study was experimentally conducted in a cargo and container inspection facility that uses a linac operating at the maximum energy of 4.5 MeV. During the in-situ measurements a SpiR-ID identifier detector Model F 8929 MGP manufactured by Mirion Technologies was used. The measurements in the driver's cab suggest that the procedure can be considered safe. However, a fast transient of δH*(10) was identified recording raised values (peaks) around 210x the threshold for public exposures in the first 9 s of each scanning procedure.

Considering the harmful effects of radiation on the fetus and the important role of radiology technologists in protecting pregnant patients and applying special considerations to pregnant technologists working in imaging departments with ionizing radiations. This study was conducted to investigate the level of knowledge and observance related to the fetal radiation protection in the Hospitals affiliated to the Arak University of Medical Sciences. This study was conducted using a questionnaire designed by researchers based on the related resources. The sample size included 71 radiology technologists. The results of this study showed that radiology technologists' awareness of the principles of radiation protection for pregnant mothers and fetuses and compliance with these principles are 53% and 79.31%, respectively. There was a significant relationship between radiation workers' education and compliance with radiation protection for pregnant patients. Moreover, there was a significant relationship between demographic characteristics and radiation protection for pregnant radiology technologists. In general, the level of awareness and observance of the principles of radiation protection for patients and radiology Technologists working in the imaging departments of Arak was average. Accordingly, holding training courses, evaluation tests and using the latest scientific information can be effective in improving the knowledge for more radiation protection.

L'objectif de cet article est de retracer le processus de mise en place de contrôles à long terme lors du déclassement du site SICN de Veurey-Voroize et de décrire comment les fonctions permettant de garantir la bonne gestion à long terme de ce site sont assurées. Le site SICN de Veurey-Voroize a, en effet, accueilli deux installations nucléaires de base dont le fonctionnement a conduit à des traces résiduelles notamment en uranium dans les sols et la nappe. L’enjeu a été de mettre en place un dispositif pérenne et efficace pour garantir que les traces résiduelles ne seraient jamais susceptibles de conduire à un impact significatif pour les populations et l’environnement.
