In this study, microbes were collected before and after disinfection using ANIOS(ANIOSURF Premium NPC) and compared the areas where the radiological technologist and the patient frequently contacted the chest X-ray. From September 1st to September 7th, 2020. in P Hospital in Deagu, 4 region were collected in a 10×10 size using a sterile cotton swab of the transport medium, and before and after disinfection results were obtained through the colorimetric method. As a result, n the X-ray tube handle Proteus mirabilis, Staphylococcus epidermidis, Bacillus spp., Candida spp., and in the Chin region Proteus mirabilis, Enterococcu faecium, Pseudomonas aeruginosa, NTM, and in the Chest region Proteus mirabilis, Enterococcu faecium, Pseudomonas aeruginosa, and in the Palm region NTM, Candida spp. were detected, and 103 CFU(Colony Forming Unit) or more were measured. After disinfection, only X-ray tube handle was detect Bacillus spp. and more than 102 CFU was measured. Microorganisms found prior to disinfection can cause opportunistic infections, Experimental results showed that Aniosulf(0.25%) is more economical and disinfectant than ethanol(70-90%) and isopropyl alcohol(70-90%). However, further research is needed on the detection of Bacillus spp. resultingly this research is useful basic data of infection control in Radiography room and prevention secondary infections.

To prevent the secondary hospital-acquired infection (cross-infection) from occurring in the general radiographic room in the department of radiology, the microbial measurement was conducted at the points making direct close contact with radiologists and patients. For the case of radiologists, the microbial measurement and incubation were focused on the x-ray tube handle of the radiation generating device, and, for the case of patients, the microbial measurement and incubation were focused on the chin supporting device, chest-contact point, and handle. Once disinfected with Aniosurf, the sterilized media were gathered and identified, and the microorganisms were confirmed. Based on the identification results, it was confirmed that the points making direct close contact with radiologists showed a value of 103 CFU for Proteus mirabilis, Staphylococcus epidermidis, Bacillus spp. and Candida spp., and that the points making direct close contact with patients showed a value of 103~5 CFU for Proteus mirabilis, Enterococcu faecium, Pseudomonas aeruginosa, NTM(Non-Tuberculosis Mycobacteria) and Candida spp.. It was also confirmed that the types and number of microorganisms gathered from the points making direct close contact with patients were greater. Fortunately, most of the involved microorganisms were observed to be on the skin surface and are known to become extinct when disinfected in accordance with the hospital-acquired infection control rules. However, since even minor exposure to such microorganisms may be lethal for patients with reduced immunity, caution must be taken. In particular, since the points making contact with patients showed a high level of microbial measurement, it was thought that it would be necessary for radiologists and personnel having frequent access to strictly disinfect the parts, such as instruments and handles, making frequent contact with patients. The purpose of this study was to announce the importance of safe microbial control in the radiographic inspection room in hospital, and this study is expected to be used as the baseline data for preventing hospital-acquired secondary infection and Nth infectious diseases.
