Given the potential risks of x rays in imaging, it is necessary to evaluate the radiation safety of medical x-ray imaging rooms and radiation information of radiographers. A descriptive study has been carried out in Qazvin, Iran, in the form of a questionnaire answered by radiography technologists in private and public imaging centers to assess the level of knowledge, attitude, and performance about x-ray exposure and safety against it. Afterward, the radiation doses of public areas of the radiography centers were measured by a survey meter. A checklist was also completed, containing items about availability of ventilation facilities in x-ray rooms, radiation warning signs, radiation work schedules, documents of periodic blood test monitoring, exposure history of radiographers by film badge, and documents of the quality control of x-ray devices. The data analysis was performed by SPSS 16 using descriptive study, t-test, ANOVA, and Pearson's correlation coefficient test. The mean attitude and knowledge scores were 6.65 ± 1.63 out of 9 and 4.82 ± 2.06 out of 15, respectively. Sex, age, and workplace had no significant effect on the radiographers' knowledge and attitude, while occupational experience had a negative relationship, and level of education had a significant direct association with knowledge of the participants (p-value<0.05). The performance of the staff was somewhat good. Almost all x-ray imaging centers had good radiation protection conditions. The annual quality control of x-ray imaging devices was ensured. The radiation protection awareness among the medical radiographers in Qazvin city needs to be improved, especially among the experienced staff.

伊朗加兹温医学 X 射线成像中心的辐射防护评估。

鉴于X射线在成像中存在的潜在风险，有必要对医用X射线成像室的辐射安全和放射技师的辐射信息进行评估。在伊朗加兹温进行了一项描述性研究，以问卷的形式由私人和公共成像中心的放射线照相技术人员回答，以评估有关 X 射线照射及其安全的知识、态度和表现水平。随后，利用测量仪对各放射中心公共区域的辐射剂量进行了测量。还完成了一份清单，其中包括X射线室通风设施的可用性、辐射警告标志、辐射工作时间表、定期血液检查监测文件、放射技师按胶片徽章的暴露历史以及X射线质量控制文件等项目。射线设备。数据分析采用SPSS 16使用描述性研究、t检验、ANOVA和Pearson相关系数检验进行。态度和知识的平均得分分别为 6.65 ± 1.63（满分 9 分）和 4.82 ± 2.06（满分 15 分）。性别、年龄和工作场所对放射技师的知识和态度没有显着影响，而职业经验呈负相关，教育水平与参与者的知识有显着的直接相关（p值<0.05）。工作人员的表现还是不错的。几乎所有X射线影像中心都具备良好的辐射防护条件。确保了X射线成像设备的年度质量控制。加兹温市医疗放射技师尤其是经验丰富的放射技师的辐射防护意识有待提高。
