현행 방사선안전관리 제도가 대학에서 방사선 실습을 하는 경우에도 적용되어 방사선 실습 교육의 부실과 방사선학의 발전을 저해할 우려가 있다. 이에 대한 방사선(학)과 교수협의회는 전국 방사선학과 학과장을 대상으로 각 대학의 방사선 실습 교육에 대한 관리체계 및 방사선안전관리 제도의 현실을 파악하기 위해 설문조사를 실시하였다. 설문조사를 통해 현행 방사선(학)과의 방사선안전관리에 대해 「원자력안전법」을 적용받는 것은 과도한 제한이며, 효과성도 크지 않다는 것을 알 수 있었다. 또한 방사선학과 실습 교육은 보건의료인 양성을 목적으로 하고 있기에 보건복지부 및 질병관리청의 지휘를 받아야 하나 원자력안전관리위원회의 관리감독을 받는 문제가 있다. 본 논문에는 「원자력안전법」 시행령을 개정하여 수시출입자의 정의에서 실습 교육을 수강하는 학생을 제외하는 방안을 기본으로 제안하였다. 추가적으로 첫째, 「고등 교육법」 일부개정법률안에 따른 방안, 둘째, 「의료법」 제37조 개정을 통해 보건복지부의 감독을 받는 방안, 셋째, 「의료기사에 관한 법률」 제20조의2를 신설하여 보건복지부의 감독을 받는 3가지 방안을 제안하였다.

Currently, with the development of technologies, X-ray examinations for medical examinations at hospital is increasing. This study was conducted to help reduce radiation exposure by measuring the exposure dose received by pediatric patients and the spatial dose of the X-ray room. Dosimeters were installed in the eyeball, thyroid gland, breast, gonads and 4 directions at a distance of 30 cm, 40 cm, 50 cm from the phantom. The dose was measured ten times each, before, and after the application of the bismuth shield under the examination conditions of the head, chest, and abdomen of pediatric patients. Under the condition of head examination, when a shielding was applied, the dose reduction rate was 68.58% for the eyeball, 72.88% for the thyroid, 84.2% for the breast, and 72.36% for the gonad. The chest examination showed reductions of 19.56% eyeball, 56.98% thyroid, 1.21% breast, and 0.68% gonad. The abdominal examination showed reduction rates of 2.6% eyeball, 10.67% thyroid, 19.85% breast, and 82.02% gonad. Spatial dose decreased by 62.25% at 30 cm, 61.16% at 40 cm, and 68.68% at 50 cm. When the bismuth shield was applied, there was a decrease in dose across all examinations, as well as a reduction in spatial dose. Continued research on the use of bismuth shields will help radiological technologists achieve their goal of dose reduction.

The apron is one of the essential protectors to reduce the exposure dose of radiological technologists. This study is to provide a guideline for purchasing the aprons with excellent performance and to help reducing the exposure dose by measuring the shielding ration and uniformity of aprons according to lead equivalent and form types. The shielding ratio of aprons were measured by using radiation generator and dosimeter. Exposure conditions were 81 kVp, 25 mAs, source to image receptor distance (SID) 100 cm and field of view (FOV) $17^{{\prime}{\prime}}{\times}17^{{\prime}{\prime}}$. Exposure areas for front type and around type aprons were divided into 9 areas and for 2 pieces type aprons were divided into 3 areas of top and 4 areas of skirt. The uniformity of aprons were measured by using fluoroscopy and Image J. The 4 regions of interest (ROI) were set into acquired images and measured uniformity by measuring the standard deviation of pixel intensity in ROIs. In continuous shielding ration measurement of aprons according to exposure area, there was not statistical significance (P>0.05). In ANOVA test of aprons, there was statistical significance (P<0.01). In the results of sheilding ratio, although the aprons had equal lead equivalent, there were difference in shielding ratio from 83.59% to 98.15%. In the results of uniformity, the front type aprons with equal lead equivalent indicated the similar uniformity. However, the around type and 2 pieces type apron with equal lead equivalent indicated the different uniformity each other, from 1.8 to 22.2. If the performance evaluation in this study were conducted regularly before and after purchase the aprons, the exposure does to patients and radiological technologists could be reduced.

Accoring to the astonlshing progress of medical science, the medical roles of the radiologic technologist are increasing gradually and specializing highly. However, there are the wide disagreements the actual roles of the radiologic technologists at clinics and the relating rules of the medical law. Therefore, it is required that the medical law should be corresponded with the actual state. To solve these problems. this study has proceeded to make the survey of the present medical law and has tried to offer the most suitable theories to the actual state. This study includes the survey of relevant professional literatures. The major contents of this study are as follows. First, medical technician is written "技士" (in Chinese character) at the present medical technician law, and that word is written wrong. So, it should be replaced with "技師". Therefore, radiologic technologist should be written "放射線師". Second, the relations between the doctor and the radiologic tecnologist should be written the "request or other words" instead of "direction". Third, in spite of the rules of the present medical law, the medical act of radiologic technologist at clinics should be belonging to the boundary of medical practice. Forth, to present the appropriate medical service to the patients, legal status of radiologic technologist as a member of medical team should be established. Fifth, it is desired that Magnetic Resonance Imaging Technology as a business of radiologic technologist should be provided for in the medical law.

A radiation imaging system used in a surgery room is mainly using C-arm which is purposed to fluoroscope. C-arm is often use to watch an operation's accuracy and progress, but not only being bombed to this first beam but also affected to this scattered beam, so now we are look for the way to reduce bombed amount of doctor, nurses and radiological technologists. We measured the exposure dose in $0^{\circ}$ spot according to the distance to find out frequency distribution of scattered ray in an operation room and found the spot which has the same exposure dose from $30^{\circ}$ distance of all directions and wrote isodose curve. We analyzed the data and found out the sudden reduction of scattered ray according to the long direction also found out that scattered ray was not related to the directions. Operators must recognize the reduction of exposure dose. Because reducing scattered ray from all directions in an operation room is really difficult. So every operators must use shelters to reduce the exposure dose and notice the safety.

Bone densitometry is a disease in which bones are easily broken due to metabolic bone disease, and DXA is used as a clinical standard test. Although DXA is a good method with good accuracy and reproducibility, it is frequently subject to test errors in testing and result analysis and analysis. Therefore, it is important to recognize the error issues that radiologists should basically be aware of when performing bone density tests, prevent erroneous diagnoses and treatments resulting from the results, and reduce the unnecessary costs associated with them. aim. The inspection must be carried out if the quality control of the equipment is basically continuously performed well before the inspection. Before starting the examination, the patient's age, sex, race, weight, pregnancy status, and any foreign objects that can be removed should be checked, and the examination should be performed in the correct posture. In addition, it is important to analyze results consistently. Radiologists, who play the most important role in ensuring accurate examinations, need to be aware of the potential for errors in advance and develop the ability to deal with the potential for errors in each examination. For that reason, regular education is considered essential.
