This study discussed the validity and necessity of compulsory recording of radiographic examination performed by radiological technologist on patients in medical institutions related to radiation exposure. Also, this study provided reasonable evidence of radiographic examination related medical records can contribute to the improvement of public health. Based on overseas cases of implementing a radiographic examination record system, the essential items to be included in medical record are the exposure date, exposure time, exposure method, exposure conditions that is tube voltage, tube current. Name and license number of the radiological technologist who performed the examination should be include in medical record. It is expected that the medical record of the total amount of radiation exposure per year would be in giving the maximum benefit with the minimum exposure to the medical radiation examination of the patient. In addition, interventional radiography medical record should also include exposure time, type and dose of the contrast medium.

Radiolysis is the process of decreasing in Radio-Chemical Purity (RCP) of [$^{18}F$]FDG by direct effect and indirect effect of self Radio-activity. The objective of our study was to figure out the ideal conditions which minimize damages of quality of [$^{18}F$]FDG using radical scavenger and controlling temperature of storage.

Most of research on environmental radioactivity is conducted in areas near nuclear power plants, so basic data about the distribution of environmental radioactivity in soil in other areas are insufficient. Therefore, in this study, divide into four categories by the land development characteristics of Incheon and the purpose of development, and confirm the stability of the Incheon through soil sample collection and gamma-ray analysis based on ⁴⁰K, ¹³⁷Cs and ²²⁶Ra (²¹⁴Pb, ²¹⁴Bi). The spectrum obtained by measuring for 80,000 seconds by using the HPGe detector was analyzed by Genie 2000 program. Soil radioactivity concentrations in urban parks of Incheon area are generally within a safe range compared to the results of the Nuclear safety and security commission. However, as ¹³⁷Cs was detected in one park, which will require continuous monitoring.

As the number of single-person households increases, the consumption of bottled water is increasing. In addition, as the public's interest in radioactivity increases, interest in the field of living radioactivity is also increasing. Since drinking water is an essential element in our daily life, it must be safe from radioactivity. In this study, gamma radiation of drinking spring water was measured and internal exposure dose evaluation was performed to determine its harmfulness. K-40 and uranium-based radioactivity analysis was performed through a high-purity germanium detector, and as a result, drinking water was detected somewhat higher than that of mixing water. Since there is no regulation on the natural radioactivity concentration in Korea, it was compared with the U.S. Environmental Protection Agency Drinking Water Regulations and World Health Organization standard. As a result, there were some items that exceeded standards. Internal exposure was evaluated according to the effective dose formula of ICRP 119. As the result was derived that a maximum of 1.17 mSv per year could be received. This result means that the dose limit for the general public may be exceeded, and it was judged that it is necessary to set an appropriate standard value and present a recommendation value through continuous monitoring in the future.

본 연구는 현 방사선(학)과의 교과목을 중심으로 임상에서의 중요도를 평가하기 위하여 전문가 집단과 임상의 방사선사들에게 설문을 실시하였다. 자료 분석 방법은 전문가 집단에는 개방형 설문지를, 방사선사들에게는 질문형설문지를 배포하여 자료를 수집 분석하였다. 교과목 중요도 분석을 위한 교과목 분류는 9개의 영역으로 분류하였고, 변수 측정을 위한 설문구성은 부서, 진료기관 등을 독립변인으로 설정하고 9개 영역의 교과목을 종속변인으로 설정하였다. 그 결과 임상의 방사선사들은 일반촬영, CT, MRI등이 포함된 영상진단기술학 및 실기 과목을 임상에서 가장 필요한 과목으로 인식하는 것으로 분석되었으며, 전문가집단의 경우 전공기초과학 과목에 높은 비중을 두고 있는 것으로 분석되었다. 본 연구를 토대로 할 때 급변하는 의료 환경에 적응하기 위한 방사선사를 양성하기 위해서는 이론과 실기가 융화된 교육과정의 개정이 필요할 것으로 판단된다.
