The various types of radiation-generator devices have been used in animal hospitals, and the safety for radiation workers is becoming important in Korea. This study investigated and analyzed the radiation safety management for diagnostic radiation-generator devices and radiation workers of animal hospital. The number of radiation-generator devices and radiation workers of animal hospital increased from 2,138 to 2,972 and from 2,644 and 5,733 for six years. The number of general X-ray, CT, C-arm, portable and dental X-ray in 2019 were 2,204, 58, 67, 770, and 14. The number of veterinarian, veterinary nurse, veterinary assistant, and others in 2019 were 4,236, 1,080, 404, and 13. The average exposure dose of radiation workers in 2018 were 0.21mSv in surface dose, 0.18mSv in depth doses. This study is expected to be the basic data for the safety management of radiation-generating devices and radiation workers in animal hospital.

The International Electrotechnical Commission (IEC) has regulated the definition and requirements of the exposure index (EI). In this study, we calculated the EI of several image receptors in digital radiography system of two different manufacturers according to the method as per IEC, and evaluated the relationship with incident air kerma. To calculate the EI, w e obtained the characteristics curve of each image receptor by increasing the incident air kerma at RQA 3, 5, 7 and 9, respectively. As a result, there was no significant difference in the EI values between different image receptors of the same manufacturer, but EI values of different manufacturer was different despite the same air kerma was incident. Therefore, understanding the characteristics of the digital radiography systems is important in order to use EI as a tool for measuring and managing the radiation dose.

There are currently many research papers on the knowledge, perceptions and actions of radiation-related staff, but hardly any papers on radiation major students in college who are to be staff members of radiation related jobs in the future. It is of course important to understand the perceptions of staff working on the lines and change their knowledge and perceptions, but in the long term it seems more efficient to understand those who are in the stage of being educated to be staff members-their knowledge and perception of radiation so that ultimately they can attain the right kind of understanding. Therefore the aim of this study is to grasp the pre-radiation staff's basic concept of radiation and space dose, their understanding of radiation safety based on this, and whether there is a change in their perception before and after the space dose measurement experiment; in the end this is to see if the space dose measurement experiment is effective in changing perception on radiation safety. This study took as its subject 64 students majoring radiation in college, I.e. pre-radiation staff members, and gauged their basic conceptualization of radiation, understanding of space dose, and understanding of radiation safety; in the X-ray room within the department the students were asked to measure space dose for themselves, so as to see whether there was a change in their understanding of radiation safety before and after the experiment, according to their understanding of the basic concept of radiation and of space dose. As a result of the space dose measurement experiment, students' increased basic knowledge of concept of radiation and understanding of the dangers of space dose were noteworthy, and accordingly their understanding of radiation safety became stricter and more conservative. In spite of this, their work ethic stayed in the lead of their understanding of radiation safety; this implies the need of a more departmentalized safety education program. Therefore instead of safety education that simply uses visual-audial material in a kind of lecture, I suggest here that there be a more experiential safety education program that enables learners to try out space dose measurement experiments for themselves, a work ethic education that aims for a conventional point of view towards radiation safety as well as a stern attitude.

Medical institutions wishing to install and operate diagnostic radiation generators must complete appointment training within one year of appointment based on the 「Medical Act」 and the 「Rules on Safety Management of Diagnostic Radiation Generator Devices」 which will come into effect on January 1, 2024. Additionally, You must receive supplementary education every three years from the date you received it. The strengthening of safety management for diagnostic radiation generators used in medical institutions means that although the radiation exposure that may occur when using diagnostic radiation generators is low, the risk of carcinogenesis may be higher than previously evaluated. In addition, safety management of diagnostic radiation generators can be said to be an essential requirement because it has been reported that the incidence of leukemia and other diseases is increasing in diagnostic radiation tests. However, the safety management training targets and programs for radiation exposure management operated by other organizations other than diagnostic radiation generators are significantly different. In addition, since the public institutions that are responsible for radiation safety management are divided, there is a risk of duplicative, excessive, and under-administrative application to medical institutions and educational institutions that install and operate diagnostic radiation generators. Therefore, we would like to determine their consistency by comparing domestic and foreign related cases and the provisions of the 「Medical Act」 and the 「Nuclear Safety Act」.

This study was conducted to examine the effect of organizational safety culture on radiologists' awareness of patient safety and safety behavior. The study was conducted based on the results of the survey, and the survey was divided into three factors: general characteristics, efforts for patient safety, and patient safety culture. As a result of the study, age, work experience, and work satisfaction were influencing factors in general characteristics, and gender, academic background, and work type were not included as factors affecting differences in patient safety awareness. In efforts for patient safety, hospital support and education, patient safety activities, and how to respond to errors were all influencing factors, especially how to respond to errors were more relevant than other items. The patient safety culture was analyzed on two items: teamwork and open communication, and both items were highly related to radiologists' awareness of patient safety.
