초록

The radiology department practice environment is conducted in a sealed imaging room for radiation safety, and radiation exposure is monitored using Thermoluminescence Dosimeter (TLD). However, closed environments pose a high risk of fine dust (PM) and volatile organic compounds (VOCs), both classified as Group 1 carcinogens. Unfortunately, environ- mental management of these hazards is often neglected. This study aimed to measure the concentration of fine dust and VOCs in closed practice rooms and propose improvements for students' health in the radiology department. Using a fine dust measuring device (Coarse Coamise S3), PM10, PM2.5, and VOC concentrations were recorded in a sealed practice room. The measuring device was placed 100cm above the floor, and six students performed chest and abdominal imaging at 30-second intervals for 20 minutes. The experimental group consisted of a radiology practice room, while the control group included a lecture room, outdoor space, and a radiology room in a hospital. Measurements were taken over four days, and PM and VOC concentrations were compared between environments. Results showed that PM2.5 concentrations averaged 5.33±1.494 ㎍/㎥ in the classroom, 7.99±3.029 ㎍/㎥ outdoors, 2.86±1.876 ㎍/㎥ in the hospital radiology room, and 3.67±1.825 ㎍/㎥ in the lab. VOC levels in the hospital radiology room were higher at 0.2191±0.139 ppm compared to other locations. Although PM and VOC levels in the lab were below WHO outdoor standards, better environmental management within sealed rooms during practice is needed to protect student health.
