In medical institutions, there are radiation-related workers such as radiological technologists, physicians, dentists, and dental hygienists who handle diagnostic radiation generators. Also, there are work assistants, such as nurses and assistant nurses, who assist in radiation treatment or transfer patients to the radiation examination room. Radiation exposure management for radiation-related workers is carried out under the 「Medical Service Act」, but there is no legal basis for work assistants, etc. And the management of radiation exposure for diagnosis is regulated by the 「Medical Service Act」, and the management of radiation exposure by therapeutic radiation and nuclear medical examination is governed by the 「Nuclear Safety Act」. Thus, to improve the management of radiation exposure for diagnosis, the regulations on radiation exposure management for diagnosis under the 「Medical Service Act」 were compared and reviewed with those of the 「Nuclear Safety Act」. As a result, the main contents are as follows. First, it is necessary to legislate to include nurses, assistant nurses, and clinical practice students who are likely to be exposed to radiation besides radiationrelated workers as subjects of radiation exposure management for diagnosis. Second, when a radiation-related worker for diagnosis is confirmed to be pregnant, the exposure dose limit should be defined. Third, it is necessary to revise the regulations on the types of personal exposure dosimeters in the 「Rules on the Safety Management of Radiation Generators for Diagnostics」. Fourth, it seems that health examination items for radiation-related workers, radiation workers, and frequent visitors should be the same. Fifth, It is necessary to unify and regulate diagnostic radiation and all medical radiation, including therapeutic radiation and nuclear medicine, in one legal system.

The use of diagnostic radiation in medical institutions is rapidly increasing. Accordingly, the collective effective dose is on the rise every year. Therefore, it is necessary to reduce the radiation exposure of the person undergoing the radiation examination as low as reasonably achievable. And we must establish a legal system to perform the safe management of radiation for diagnosis efficiently. In this way, I went over the problems of the Act and Subordinate Statutes regarding radiation safety management for diagnosis. As a result, the main contents are as follows. First, in the 「Medical Service Act」, there is no basis for the Safety Inspection Institute of Radiation and Radiation Exposure Measuring Institutes. And there are no provisions concerning delegation of administrative disposition. Therefore, it is necessary to secure legal justification by providing the basis for the Safety Inspection Institute of Radiation along with Radiation Exposure Measuring Institutes and the basis for administrative dispositions against these institutions in the 「Medical Service Act」. Second, the 「Rules on the Installation and Operation of Special Medical Equipment 」 should be integrated with the 「Rules on the Safety Management of Radiation Generators for Diagnostics」 to unify administrative procedures such as reporting for radiation special medical equipment for diagnosis. Third, in the case of violating the diagnostic radiation safety management standards in the 「Rules on the Safety Management of Radiation Generators for Diagnostics」, it is necessary to supplement the insufficient sanctions such as administrative disposition. Fourth, regulating diagnostic radiation and therapeutic radiation used in medical institutions with the dual legal system of the 「Medical Act」 and the 「Nuclear Safety Act」 is not efficient in the safety management of diagnostic radiation. Therefore, it is necessary to uniformly regulate diagnostic radiation and all medical radiation, including therapeutic radiation and nuclear medicine, in the 「Medical Service Act」 system.

The examination using diagnostic x-ray equipment is one of the most useful diagnostic equipment for identifying information in the human body in diagnostic radiology. For this reason, the number of examinations has recently increased a lot. Increasing the number of examinations will accelerate the aging of the device. In addition, this makes them aware of the importance of quality control for the diagnostic x-ray device. Particularly, in a diagnostic x-ray device, quality control refers to an act of always maintaining a certain level of image quality by identifying and correcting all problems that may lead to reduction of the diagnosis area in advance. Therefore, this study summarizes and reports general information about quality control in examinations using diagnostic x-ray equipment.

The diagnostic multileaf collimator(MLC) was designed for patient dose reduction in diagnostic radiography We used monte carlo simulation code (MCNPX, LANL, USA) to evaluate efficiency of shielding material for making diagnostic MLC as preliminary study. The diagnostic radiography unit was designed using SRS-78 program according to tube voltage (80,100,120 kVp) and acquired energy spectrums. The shielding material was SKD11 alloy tool steel that is composed of 1.6% carbon(C), 0.4% silicon(Si), 0.6% manganese (Mn), 5% chromium (Cr), 1% molybdenum(Mo) and vanadium(V). The density of it was $7.89g/cm^3$.Using tally card 6, we calculated the shielding efficiency of MLC according to tube voltage. The results was that 98.3% (80 kVp), 95.7 %(100 kVp), 93.6% (120 kVp). We certified efficiency of diagnostic MLC fabricated from SKD11 alloy steel by monte calro simulation. Based on the results, we designed the diagnostic MLC and will develop the diagnostic MLC for reduction of patient dose in diagnostic radiography.

Through this study, the purpose of this study is to harmonize the quality assurance system of diagnostic radiation generator inspection bodies with current international standards, standardize the diversity of inspection bodies, provide consistent inspection services to medical institutions, and improve review efficiency of regulatory agencies. We compared and reviewed the quality assurance systems of all domestic diagnostic radiation generator and defense facility inspection bodies. For international harmonization, we reviewed international and domestic and international standards, including ISO/IEC 17020, and added and reflected the requirements of regulatory agencies. The quality assurance systems of all inspection bodies included all required items in compliance with ISO/IEC 17020, but some of the quality procedures showed differences. Standards were drawn up through expert meetings for items where differences were compared and analyzed, and rules for safety management of diagnostic radiation generators and amendments to these regulations were proposed. The results of this study are expected to improve the operational efficiency of inspection bodies and the work efficiency of regulatory agencies for inspection bodies, and international harmonization in accordance with international standards such as ISO/IEC 17020 should be continuously maintained.

1895년에 독일 뢴트겐에 의해 발견된 이후 X선은 1896년부터 의료목적으로 사용된 기록이 있으며, 한국에 도입되어 진단용X선발생장치로서 환자 진료에 사용하기 시작한 역사는 1911년경부터 조선총독부의원과 세브란스의원에 도입되어 사용하게 되었다. 최근 의학 및 의용공학의 발전으로 방사선을 이용한 진단 기술의 발전과 건강에 대한 국민의 의료욕구가 증가함에 따라 방사선을 이용한 질병의 진단과 치료 방법에서 새로운 기법이 개발되고 그 이용은 지속적으로 증가되고 있는 추세이다. 방사선의 이용은 진단 및 치료에 중대한 이득을 제공하고 있으나 그 이면에는 최적화 및 정당화 되지 않은 방사선의 피폭으로 장애 및 유해요인이 초래되는 것은 부인할 수 없다. 이와 관련하여 방사선을 이용하여 검사 및 치료를 시행함에 있어 피폭선량 최적화를 위한 기술적 노력은 방사선 관계자의 막중한 의무이다.
