The advent of PET/CT examinations has revolutionized cancer treatment, offering greater precision in diagnosis. Nonetheless, the ionizing radiation exposure during the examination could cause a cancer risk. Hence, this study aimed to evaluate the radiation dose and radiation-induced risk associated of whole-body PET/CT scan that includes the 18F-FDG tracers. For this retrospective study, 40 participants were studied, with an even number of males and females. The average age and weight of the participants were 53.77 ± 15.78 years and 66.59 ± 16.94 kg respectively, and they were administered 424.64 ± 121.19 MBq of 18F-FDG before the PET/CT commenced. The IDAC-Dose 2.1 program was employed to calculate the absorbed dose and effective dose in organs such as the bladder, brain, lung, kidneys, colon, red bone marrow (RBM), stomach, liver, and thyroid. The potential risks of cancer were evaluated using the lifetime attributable risk (LAR) via a 3rd order polynomial approach based on the information provided in the Biological Effects of Ionizing Radiation (BEIR) VII report. The effective dose was 20.1 ± 7.9 mSv, and the ratio of E to administered activity is 1.612 × 10-2 mSv/MBq, which is in line with the ICRP standard. The study found that the average incidence of cancer among men and women was 7 and 8 cases per 100,000 examinations, respectively, with effective dose between 3.2 mSv to 27.3 mSv. In summary, the risk of cancer associated with current whole-body 18F-FDG PET/CT examinations is low, but it is essential to mitigate radiation exposure during these examinations and utilize suitable techniques to prevent stochastic effects from low-dose radiation exposure.

This study highlights the significance of radioprotection in interventional radiology, focusing on the assessment of Effective Dose values to which patients are exposed. To facilitate this, we developed a semi-automatic software employing Optical Character Recognition technology. This software analysed 1125 interventional procedures conducted between January 2021 and September 2023 at a large Brazilian hospital. The database includes the type of procedure, Air Kerma value, Kerma-Area Product, number of cineangiography images, and exposure duration, all realized on an Artis Zee® (Siemens Healthineers, Germany) C-arm. We established Local Diagnostic Reference Levels (LDRLs) and calculated Effective Dose values using the PCXMC 2.0 Monte Carlo simulation software. These calculations were based on data from the hospital and LDRLs determined in subsequent studies. The findings reveal that both the LDRLs and the calculated Effective Dose generally fall below the values reported in existing literature. This underscores the efficacy of our methodology in enhancing radioprotection and dose monitoring within the studied hemodynamics sector.

In veterinary radiology, The dose to radiation workers, animals, and the public should be reduced as low as reasonably achievable. Immobilization of the pets is necessary for obtaining images with acceptable image quality. The adopters are usually asked to immobilize their pets during the imaging. Therefore the dose equivalent values received by the animal adopters are also important. This study aims to assess the dose to the hands and whole body of the adopter and the entrance skin dose (ESD) to the animals undergoing radiographic imaging using LiF: Mg, Ti (TLD 100) for one month of work in a veterinary hospital in Shiraz. The results showed that the dose received by the animals varied from 0.20 mSv to 0.53 mSv. The average dose equivalent values to hands, Hp(0.07), and body, Hp(10) of adopters are 0.35, and 0.14 mSv Respectively.

The multifaceted applications of nuclear technology, especially in cancer treatment through radiotherapy, bring considerable benefits to our daily lives but also necessitate the imperative for effective strategies to effectively mitigate radiation-induced issues. While strict compliance with usage specifications is essential, ensuring proper protection against radiation-induced damages is crucial. Selenium, in its various forms including selenomethionine, Ebselen, and sodium selenite, emerges as a promising radioprotective agent with demonstrated efficacy across diverse radiation-injured organs, highlighting its significance as an effective and potent antioxidant that affordable for most patients. Abundant experiments have exhibited the capacity of selenium-containing compounds and metabolites to function as valuable radioprotective adjuvants, emphasizing their potential in safeguarding against the adverse effects of radiation exposure. To harness the full radioprotective potential of selenium, further research to optimize selenium supplementation strategies is in need, taking into account factors such as timing and dosage, particularly in the context of radiotherapy.

The relationship between radiation dose indices and patient size was investigated in adult brain CT scans to assess the significance of considering the patient size for radiation dose management. Two hundred patients who underwent brain CT using automatic exposure control were enrolled. The radiation dose indices (volume CT dose index, CTDIvol; size-specific dose estimate, SSDE; dose length product, DLP) were compared with the head size indices (effective diameter, ED; water-equivalent diameter, WED) and body weight. The CTDIvol and SSDE correlated positively with the ED and WED. The correlations were higher for the WED than the ED and for the CTDIvol than the SSDE. Although the DLP also correlated positively with the ED and the WED, the correlations were lower than those for the CTDIvol and the SSDE. The CTDIvol and SSDE showed significant positive correlations with body weight, but the correlations were lower than those for the ED. In conclusion, the radiation dose indices in adult brain CT correlate with the head size indices. Consideration of the head size indices is recommended for radiation dose management in brain CT. The relationship between the radiation dose indices and body weight may be of some significance when the head size indices are not readily available.

Background: Dental radiography, a pivotal diagnostic technique in dentistry, plays a significant role in patient care. Despite its indispensability, the use of ionizing radiation in dental radiography entails inherent risks. Dental students, as future practitioners, bear the responsibility of acquiring thorough knowledge in radiation protection to ensure the safety of both patients and operators. Aim: This study seeks to evaluate the levels of awareness, knowledge, and approach regarding ionizing radiation among dental students enrolled in the dentistry program at Jazan university (JU). Material and Methods: A descriptive, cross-sectional survey was carried out involving 82 dental students, with a participant distribution of 63 males (77%) and 19 females (23%) across different academic years. The survey utilized a structured questionnaire designed to assess awareness regarding deterministic and stochastic effects of ionizing radiation, as well as various aspects of radiation protection practices. Demographic factors, including gender and academic year, were scrutinized for their potential impact on radiation protection awareness. The collected data underwent statistical analysis using chi-square tests implemented in SPSS to explore any significant associations. Results: The study included 82 dental students with varying age distributions. Age-wise, 39% fell within the 21-23 years range, 31% were between 18-20 years, 24% ranged from 24 to 26 years, and 6% were older than 26 years. Participants were distributed across different academic years, with the largest group being fourth-year students (25%), followed by fifth-year students (15%). Female students exhibited higher awareness of the National Council on Radiation Protection (NCRP) and International Commission on Radiological Protection (ICRP) recommendations, and the practice of standing behind lead barriers during exposure. Conclusion: This study underscores the overall elevated awareness and knowledge regarding radiation protection among dental students. Nevertheless, distinct gender-related variations in specific facets of awareness were identified, underscoring the necessity for targeted educational interventions. The findings support the integration of comprehensive radiation safety education into dental curricula, aimed at fostering responsible utilization of radiographic procedures and ensuring the well-being of both patients and operators.

Le centre nucléaire de Marcoule, mis en service en 1955 par le CEA, accueille les premiers réacteurs français de dimension industrielle. Leur exploitation pose un immense défi en matière de sécurité radiologique, auquel répond la création du Service de Protection contre les Radiations (SPR). Ce dernier rationalise la radioprotection et élabore sa doctrine en même temps qu’il développe ses moyens de contrôle et de surveillance. Conscient de l’ampleur de sa mission, le SPR cherche à réduire sa tâche en promouvant la contribution active du personnel à sa propre protection. Pour ce faire, il développe un programme d'éducation en matière de risque radioactif. Celui-ci est destiné aux agents de Marcoule, mais aussi au grand public, parmi lequel sont recrutés les travailleurs du nucléaire. Ce programme éducatif, illustré par le dessinateur Jacques Castan, participe ainsi de l’effort de rationalisation de la radioprotection entrepris par le SPR.

Introduction: Radiographers play a vital role in patient radiation protection. Their training, supervision, and involvement in radiation protection programmes require greater attention from all stakeholders. Methods: This cross-sectional study was conducted between March and August 2023 to assess Radiographers’ attitudes toward the principles of patient radiation protection in the Souss Massa region of Morocco. An anonymous questionnaire containing 22 questions was sent to 80 radiographers practicing in the Sous Massa region. Results: 67.5% of the radiographers confirmed that they did not use a guide to radiological procedures. 85% of them confirmed that they had checked for the possibility of pregnancy each time a woman of childbearing age was involved in a conventional X-ray, compared with 97.5% who checked for the possibility of pregnancy in a CT scan. 97.5 % of our participants said that they automatically (without medical advice) repeated the X-ray examination if the image was not interpretable. 90% of radiographers said that they did not report parameters for dose estimation for each conventional X-ray examination, and 72.5% did not report data for dose estimation for CT-scan examinations. The results showed no association between gender and professional experience on the one hand and radiographers' practices on the other. Nevertheless, there is an association between the workplace and certain radiographers' practices, indicating the lack of a regional strategy aimed at standardizing procedures and radiation protection practices at the level of all radiology departments. Conclusion: It is vital to launch a patient dose management program in the Souss Massa region and campaigns to raise radiographers’ awareness of recommended patient radiation protection practices.
导言：放射技师在患者辐射防护方面发挥着至关重要的作用。他们的培训、监督和参与辐射防护计划需要所有利益相关者给予更多关注。研究方法这项横断面研究于 2023 年 3 月至 8 月间进行，旨在评估摩洛哥 Souss Massa 地区的放射技师对患者辐射防护原则的态度。研究人员向在 Sous Massa 地区执业的 80 名放射技师发送了一份包含 22 个问题的匿名调查问卷。结果显示67.5%的放射技师确认他们没有使用放射程序指南。其中 85% 的放射技师确认，每次为育龄妇女进行常规 X 光检查时，他们都会检查是否有怀孕的可能，而 97.5% 的放射技师在进行 CT 扫描时会检查是否有怀孕的可能。97.5%的参与者表示，如果图像无法解读，他们会自动（在没有医嘱的情况下）重复 X 光检查。90% 的放射技师表示，他们没有报告每次常规 X 光检查的剂量估算参数，72.5% 的放射技师没有报告 CT 扫描检查的剂量估算数据。结果显示，性别和专业经验与放射技师的工作方法之间没有关联。不过，工作场所与某些放射技师的做法之间存在关联，这表明缺乏一项旨在统一所有放射科的程序和辐射防护做法的地区性战略。结论：在 Souss Massa 地区启动患者剂量管理计划和开展宣传活动，提高放射技师对建议的患者辐射防护措施的认识至关重要。

In this specific study, the concentration of radon, radium content, and annual effective dose were meticulously measured and calculated utilizing solid-state nuclear track detectors (CR-39). The research was centered on soil samples extracted from diverse locations in the northern regions of the West Bank, Palestine. A comprehensive set of 40 soil samples was systematically collected from Tulkarm, Jenin, and Tubas Governorates. The average concentrations of 222Rn and 226Ra in Tulkarm, Jenin, and Tubas governorates were found to be 505.2 Bq/m³ and 22.0 Bq/kg; 528.4 Bq/m³ and 23.1 Bq/kg; and 515.3 Bq/m³ and 22.5 Bq/kg, respectively. Calculating the overall total average effective dose for these governorates yielded values of 17.5, 18.3, and 17.8 mSv/year, respectively. These values slightly exceed the action levels (3-10 mSv/year) recommended by ICRP-1993. It's noteworthy that the measurements established in this study provide a foundational database of activity levels, serving as a reference for future studies assessing the potential impacts of events to come.
