Radiation and radioisotopes have a high value in terms of utilization that can be used in convergence with various fields. However, due to the specificity of radiation, the use of radiation and radioisotopes is more difficult than in other industrial fields and also involves complex regulations. There are no clear industrial technology standards in these fields. Therefore, the growth of the radiation industry, especially including small companies, is being delayed. Since industrial technology standards play an important role in providing an institutional basis for the continuous development and settlement of domestic technology, the development of technical standards for the radiation and radioisotope industries can lead to systematic growth of the domestic radiation industry. To this end, the technology classification of the radiation industry was promoted and classified into 7 major categories, and detailed classification was divided according to the characteristics of each technology. In addition, a demand and perception survey on the need for industrial technology standards was conducted on RI licensed institutions and companies, and as a result, 61.4% responded that it was necessary, and in particular, they recognized the need for radiation safety(63.3%). In this paper, the technical classification for the radiation field is presented as the first step in the development of industrial technical standards for the radiation industry. In addition, the plan of the current status information and preparation of standard procedures of each category will be discussed.

Background: This study aims to analyze radiation safety management and regulatory perceptions, focusing on companies that must report radiation sources. The intent is to reduce the gap between regulation measures and addressing real concerns while improving practical safety management measures and regulations for all stakeholders. Materials and Methods: Radiation safety officers at a total of 244 reporting companies using radiation generators (79.8%) and sealed radioisotopes (15.1%) were surveyed using a questionnaire. Results and Discussion: The perception that regulation is stronger than the actual risk of the radiation source used was 3.47 points (out of 5 points), indicating a score above average. The most important factors and considerations were education and training (48%) as a human factor, safety devices of the radiation source (71.3%) as a hazardous material factor, the use of radiation (50.8%) as an organizational environment, and the radiation effect of nearby facilities (67.2%) as a physical environment. Radiation safety management educational experience (F= 5.030, p< 0.01), the group with high subjective knowledge (t= 6.017, p< 0.001), and the group with high objective knowledge (t= 1.989, p< 0.05) was found to be better at radiation safety management. Conclusion: It is necessary to standardize the educational experience regarding radiation safety management because each staff member has individual differences in educational experience. It is necessary to provide more information on how to solve radiation accidents via educational content. Applying radiation safety regulations based on the factors that significantly affect radiation safety management shown in this survey will help improve safety.

본 연구는 방사선의 위험 인식이 방사선 관리와 편익에 미치는 구조적 관계를 실증적으로 분석하고자 수행되었다. 충북소재 1개 4년제 대학의 방사선 관련 대학생들을 대상으로 2013년 4월 1일부터 5월 31일까지 자기기입식 설문조사를 통하여 직접 자료를 수집하였다. 분석결과 방사선 위험 인식이 높을수록 방선선 관리에 대한 인식이 높은 것으로 나타났으며, 이는 편익에 유의한 영향을 미치는 것으로 나타났다. 비록 방사선 위험 인식이 방사선 편익에 직접적인 영향을 미치지는 못하였으나 방사선 관리라는 매개변수를 통해 방사선의 편익에 대한 긍정적 인식이 높아짐을 시사한다. 따라서 방사선의 원활한 활용과 편익을 높이기 위해서는 적절한 방사선 관리의 필요성을 강조하는 교육이 실행되어야 할 것이다.

In this study, we analyzed the relationship between four elements: long-wave radiation, the direction of the building, BVR (Building View Ratio), and cloud amount. We examined how long-wave radiations surrounding a building influences the perception of heat in the summer. The results are as follows. (1) Long-wave radiation and BVR are highly correlated regardless of geographical direction. (2) Especially, during dawn in a clear day, areas with high BVR observed high levels of long-wave radiation. (3) This correlation suggests that higher BVR in urban areas will result in a greater number of tropical nights.

While high-dose ionizing radiation results in long term cellular cytotoxicity, chronic low-dose (<0.2 Gy) of X- or ${\gamma}$-ray irradiation can be beneficial to living organisms by inducing radiation hormesis, stimulating immune function, and adaptive responses. During chronic low-dose-rate radiation (LDR) exposure, whole body of mice is exposed to radiation, however, it remains unclear if LDR causes changes in gene expression of the whole brain. Therefore, we aim to investigate expressed genes (EGs) and signaling pathways specifically regulated by LDR-irradiation ($^{137}Cs$, a cumulative dose of 1.7 Gy for total 100 days) in the whole brain. Using microarray analysis of whole brain RNA extracts harvested from ICR and AKR/J mice after LDR-irradiation, we discovered that two mice strains displayed distinct gene regulation patterns upon LDR-irradiation. In ICR mice, genes involved in ion transport, transition metal ion transport, and developmental cell growth were turned on while, in AKR/J mice, genes involved in sensory perception, cognition, olfactory transduction, G-protein coupled receptor pathways, inflammatory response, proteolysis, and base excision repair were found to be affected by LDR. We validated LDR-sensitive EGs by qPCR and confirmed specific upregulation of S100a7a, Olfr624, and Gm4868 genes in AKR/J mice whole brain. Therefore, our data provide the first report of genetic changes regulated by LDR in the mouse whole brain, which may affect several aspects of brain function.

by providing objective information regarding medical radiation for elementary, middle, and high school students in Korea, who are expected to have a high ripple effect in education, and by analyzing behavioral changes in the selection of medical radiation, this study aimed to deduce the basis for educational intervention. The tools used in the study were a questionnaire, including questions about perception, knowledge, attitude, and behavior toward medical radiation; video and Power-point materials for the lesson; simulated radiation diagnosis selection form; and radiation treatment selection form to find out about behavior. A post-test demonstrated that the objective knowledge about medical radiation of all the students turned out to be significantly higher (p<0.000) after the lesson compared to before the lesson. However, there were no statistically significant behavioral changes. Rather, for high school students, the behavior of selecting medical radiography and treatment was significantly lower (p<0.000) after the lesson. For the more impressionable children in the lower grades, the lesson must not only provide an opportunity to understand and pay attention to diverse viewpoints, but also encourage them to make ethical decisions based on value. Since it can be predicted that attitude or behavioral changes through education or publicity can be expected from adults older than high school students, issues regarding dangers like radiation exposure must be treated as an issue of value judgment predicated on multifaceted considerations.
