Fundamental data on the safety status is necessary to develop and operate the additional policies related to the radiation safety, however, few studies have been conducted to investigate the status quantitatively. In this study, out of the areas related to radiation safety, the status of the radiation worker, ambient radiation and the environmental radiation were examined in the quantitative aspect using diverse statistical methods. In the results of that, following information were obtained. First, out of the radiation workers engaged in 9 businesses as of end of 2014, the business having highest exposure dose is NDT showing significantly high than other businesses. Second, the average difference of the exposure doses in radiation workers in 9 businesses in 2014 compared to that in 2010 was not statistically significant at significance level of 5% (p=0.221). Third, the average of the environmental radiation in Gyeonggi-do was high than the Jeollabuk-do. The results of this study are anticipated to assist to utilize the basic data for the workers on radiational works, daily living radiation, and the safety control related to the environmental radiation, and to establish the policy of radiation protection in the future.

Radiation Following the 2011 Fukushima nuclear accident in Japan, public interest and anxiety about radiation safety increased, and vague anxiety about commonly exposed living radiation was generated. The Atomic Energy Safety Commission has been conducting a survey of processed products that advertise "negative ions" and "far-infrared" emissions under the Living Radiation Safety Management Act. In this study, in-depth analysis was performed from a statistical point of view using the measurement data presented in the Nuclear Safety Committee's actual survey analysis report as secondary data. As a result, there was a statistically significant difference (p<0.005) between latex and civil affairs products. There were also statistically significant differences (p<0.05) in the results of testing whether there were significant differences in the annual exposure dose between groups after categorizing 71 civil products, including radon beds, into bed, bedding, and living and other categories. The correlation analysis results also confirm that, as is commonly known, the annual doses received from processed products are associated with radon derived from U-238 and Th-232.

The study attempted to analyze items presented in Act on safety control of radioactive rays around living environment, which has been recently enacted. The test items have been divided into cosmic rays, cosmic rays, terrestrial radiation, and byproduct, etc., and the selected locations for measurement included an airplane at 8000m in the air, mountainous area at 1000m above sea level, 15m-underground building, construction site, and seashore at 0m altitude. The test showed that, based on cosmic rays, plane at 8000m in the air had 4.91mSv/y of effective dose per year. The mountainous area at 1000m above sea level, which was chosen to measure cosmic rays and terrestrial radiation, was measured 0.35mSv higher than the seashore at 0m in altitude due to the effect of cosmic rays and terrestrial radiation from the greater height above sea level. The construction site, chosen as a location to measure byproduct, showed the highest value among the items with 6.66mSv, which is as 10times high as that of a completed building. The seashore at 0m in altitude had 5.96mSv, and, 15m-underground building, based on terrestrial radiation, was the lowest with 4.91mSv. This suggests that, despite the assumption that terrestrial radiation will have greater effect deeper underground, it did not affect inside the building significantly. This study showed that the items presented in Act on safety control of radioactive rays around living environment were not close to effective dose limit for radiation workers proposed by ICRP. However, they were between 4 and 7 times higher than that for general public. This suggests that there should be continuous research on and attention to Safe Management of Daily Surrounding Radiation Act, which is still at its beginning stage.

This study was conducted to understand the motivation for major selection and degree of satisfaction with major for university students in the department of Radiology, and to analyze the effect university life adjustment in COVID-19. From Jung 20 to July 20, 2021, 308 students in grades 1~4 were enrolled at universities in Busan and Gyeongnam. Factors influencing university life adjustment were found to have a good adjustment when majoring was selected with personal motive rather than social motive. Among the sub-factors of major satisfaction, general satisfaction and satisfaction with surrounding relationships had a positive effect on university life adjustment. Therefore, in order to adapt to healthy university life, it is necessary to secure closeness between school, professor, and students, and it is desirable to provide students with opportunities to experience various education by recognizing the rapidly changing policy changes in education to increase major satisfaction. Based on the results of this study, it is expected that the results of this study will be used as basic data for successful university life of students in the department of radiology.

원자력발전소 안전성 확보의 가장 중요한 요소는, 원전 시설 내에 근무하는 종사자와 원전 주변 주민은 물론, 생활 환경을 방사선과 방사성 물질로부터 보호하고, 원전운영으로 인한 각종 영향이 법적 제한치 이내에서 최소화되도록 관리하는 것이다. 방사선 안전 관리가 제대로 이루어질 때 국민적 신뢰가 확보되고, 원전 사업 기반은 더욱 튼튼하게 뿌리를 내리게 될 것이다. 96년도에 수행한 주요 방사선 안전 관리 실적에 대해 방사선 관리, 방사성 폐기물(이하 방사물) 관리, 환경 방사능 관리, 방사능 재해 등의 분야로 나누어 점검해 본다.

Various radioactive materials exist around us. In recent years, as interest in health has increased along with the improvement of the quality of life, examinations using radiation are also increasing. This research defined aforementioned radiation as a living radiation and developed a measurement to measure general knowledge people have on it. Eighteen reliable items were developed; current status on general knowledge regarding the safety of living radiation was analyzed using the items. As a result, a group with radiation-related education got statistically higher score than a group without such education. Correlation analysis and regression analysis showed that higher attention on usual safety leads into the greater knowledge on safety of living radiation. Therefore, this research shed lights on the necessity of radiation safety-related education in current educational course in schools.

최근 원자력발전소주변 환경방사선에 대한 국민적 관심이 고조되고 있으나 환경중 방사능 축적에 대한 허용기준치가 정립되어 있지 않아 효과적인 대 국민 홍보에 한계가 있다. 따라서 원전 주변 주민의 생활습관을 파악하여 섭취량을 품종별로 분류하여, 조사, 분석함으로서 환경시료중 방사능 허용농도를 설정함으로서 원자력발전소 주변 환경방사능 농도를 설정된 허용농도와 비교하여 원전의 안전성에 대한 대 국민 이해 및 신뢰 회복에 이바지 하고자 한다. 또한 최대허용농도를 기준으로 삼던 기존의 방식이 퇴색하고 ALI［l］를 이용한 국내 실정에 맞는 식품 중 허용농도 설정의 필요성이 대두되고 있는 현 실정을 감안하여 ALI를 이용하여 식품 중 최대허용농도를 설정하고자 한다.

국내에서는 대한항공이 2006년 8월 17일에, 북극 항공로를 처음으로 운항하기 시작한지 벌써 3년이 넘어서고 있는 현실에서 국내 항공기의 승무원 및 승객 보호를 위한 우주방사선 안전 기준 연구가 시급한 것이 현실이다. 특히 우주방사선 관리의 필요성을 명시한 생활주변방사선 안전관리법안이 현재 국회 심의중이고, 이에 따른 우주방사선 관련 정책 개발 연구 과제를 한국천문연구원 태양우주환경연구그룹에서 진행 중이다. 이 과제의 현재까지의 진행 상황 및 안전조치 방안들에 대한 나름의 제안에 관해서 이번 발표에서 다루어 질 것이다.
