Abstract

|
This study was conducted by simulating the same environmental conditions as the actual biopsy to observe the change in formaldehyde(HCHO) concentration in the indoor air during ultrasound guided biopsy. Changes in HCHO concentration in the room were measured by successively performing five steps: sealing the ultrasound room, ventilation, opening formalin containers, sealing formalin containers, and re-ventilating. Trends of measured HCHO concentration changes were visualized using graphs. As a result of analyzing the consistency of the concentration change values measured three times using the intra-class correlation coefficient, it was found to be 0.989, which was statistically significant(p<0.05). Based on the results of this study, we hope that medical workers working in the HCHO exposure environment of the field of radiology part will improve their awareness of the necessity of exposure management at work, and actively discuss the establishment of an environment for exposure control and preparation of countermeasures.
