診斷放射線安全管理 및 職務環境에 관한 硏究 = (A) Study on the Diagnostic Radiation Safety Management and Actual Job Environment

다국어 초록 (Multilingual Abstract)

This study surveys the diagnostic radiation safety management and actual job environment of radiological technologists employed in medical institutions. The one purpose of this study was to help prevent medical users from harmful health disorders caused by radiation, and design promising health education programs for the radiation safety management of radiological technologists. Moreover, in regard to the importance of radiological examination as a task of radiological technologists in their job owing to its diversified and specialized examination technologies, the other purpose of this study was to identify every job environment due to such radiological examination so that it could provide basic materials for better level of radiological technologists' job environment.
To meet these goals, this study surveyed radiological technologists working at medical institutions in Daejeon metropolitan city. In details, total 241 radiological technologists employed at 61 medical institutions in Daejeon (34 clinics, 21 hospitals, 3 general hospitals, 2 private university hospitals and 1 national university hospital) were asked to join a questionnaire survey from July 20 to Aug. 12, 2006. The results of survey can be summed up as follows: In view of the year of radiation equipment made for each medical institution, 44.4% of all radiation equipments were made during 1996 to 2000; 37.8% were made before 1995; and 55.9% of equipments made after 2001 were installed at private university hospitals. In regard to awareness about radiation equipment models and types according to general characteristics, it was found that there were more or less significant differences depending on sex, age, marital status, academic career and institution type on statistical level (p<0.05). In terms of whether to control dose of radiation equipment and the necessity to do it for each institution type, it was found that 'the percentage of always controlling dose' at private university hospital and other institutions amounted to 79.4% and 94.1% respectively, which indicated significant differences on statistical level (p<0.01). In terms of whether to perform dose correction for radiation equipment at each institution, 71.7% of 'yes' respondents came from general hospital. And in terms of dose correction period, private university hospital comprised the highest percentage of institutions under monthly dose correction (67.4%), while clinic and hospital comprised 31.3% and 27.3% respectively of all institutions under annual dose correction, which indicated significant differences on a statistical level (p<0.01). In terms of whether to put on legal radiation dosimeter before work, 'always put on' respondents amounted to 81%. In terms of awareness about radiometry using legal radiation dosimeter, 'yes', 'moderate' and 'no' respondents amounted to 47.4%, 34.0% and 18.3%, which showed significant differences only depending on academic career and institution type (p<0.05). 70% of institutions except clinic and hospital answered that they conducted education in radiation safety management (p<0.001), and 'maintenance education' comprised the most of safety management education types (64.3%), which indicates significant differences on statistical level (p<0.01). In terms of whether to conduct health examination, 'yes' respondents amounted to 91.3% (p<0.001). In terms of what is tested in health examination, it was found that blood + thoracic X ray + other exams amounted to 40.8%, which were followed by blood + thoracic X ray (30.3%) and blood test only (28.9%). It also indicates significant differences on statistical level (p<0.01). In terms of frequency of shielding for critical organs upon irradiation for infant patients according to institution type, it was found that general hospitals amounted to the most (50.9%) of 'always' respondents (p<0.01). In terms of whether to adjust diaphragm and apply appropriate conditions upon irradiation, national university hospitals amounted to the highest rate (94.7%) in 'always' response, which indicates significant differences on statistical level (p<0.001). In terms of rating aware management, it was found that 'yes' respondents were significantly more than 'no' respondents on statistical level (p<0.001). In terms of survey on job environment, it was found that the highest score amounted to 25 out of full 25 points, while the lowest score to 5 points (average score = 13.5 points). Out of general characteristics, the older age group led to the more significant differences (p<0.05), and each of institution types showed significant differences from national university hospital (p<0.001). It was noted that the awareness about radiation protection was a factor affecting the awareness about radiation exposure, and the factors affecting the awareness about radiation protection included safety education, awareness of exposure, job environment, radiation safety management and awareness of job environment. And the factors affecting the awareness of job environment included working career, institution type, awareness of protection, radiation safety management and job environment.
