Abstract

It is going to select one X-ray generating device for diagnosis in a radiography laboratory at K university in Gangwon-do to detect bacteria on the surface contamination of tables, IP cassettes, and lead gowns for medical radiation shielding and to inform students of the need for proper disinfection control and hand hygiene. Then disinfection was carried out with tissue, tissue cleaner and 70% alchol and immediately collected with sterile cotton swabs to assess the contamination distribution status and disinfection effects of the surface. The results of measuring the degree of contamination on the surface showed that the largest number of bacteria were detected in Apron, and the evaluation of the disinfection effects according to surface contamination showed a noticeable effect at 70% Alcohol in IP Cassette, and the disinfection effect was the same for Apron. Therefore, in order to prevent bacterial infections among students, basic hand washing and regular disinfection should be performed before the practice to prevent infection.

본 연구는 강원도 지역 K 대학교내 방사선촬영 실습실의 진단용 엑스선 발생장치 1대를 선택하여 table, IP cassette, 의료방사선 차폐용 납 가운의 표면 오염도의 세균을 검출하여 적절한 소독관리와 학생들의 손 위생의 필요성을 알리고자 한다. 그 후 휴지, tissue cleaner, 70% alchol로 소독을 실시하고 즉시 멸균면봉으로 채취하여 표면의 오염 분포상태 및 소독효과를 평가하였다. 표면의 오염 분포도를 측정한 결과는 Apron에서 가장 많은 균이 검출되었고 표면 오염도에 따른 소독효과 평가는 IP cassette에서는 70% Alcohol에서 두드러진 효과가 나타나고 Apron와 Table의 경우는 Tissue cleaner, 70% Alcohol에서는 소독효과가 동일함을 확인하였다. 따라서 학생들 사이에서 세균 감염을 방지하기 위하여 실습 전에 기본적인 손 씻기, 주기적인 소독을 하여 감염을 방지하여야 한다.
