Abstract
이번 연구에서는 송변전 지리정보 시스템(Transmission and substation Geographic Information System: TGIS)을 이용하여 일반인들이 판단한 고압 송전탑 및 송전선, 변전소와 거주지 간 거리 인식이 실측 거리와 일치하는지 확인해 보았다. 총 725명의 응답자 중 136명이 고압 송전탑 및 송전선, 변전소가 눈에 보이는 거리에 있다고 응답하였고, 이 중 114명이 TGIS로 분석할 수 있는 유효한 주소를 제공하였다. 114명 중 42명(36.8 %)은 실측 거리보다 인식 거리가 짧았으며, 15명(13.2 %)은 인식 거리보다 실측 거리가 짧았다. 일반인들의 고압 송전탑 및 송전선, 변전소와 거주지 간 거리 예측의 타당도가 높지 않은 점을 바탕으로 했을 때, 이를 극저주파 전자기장 노출량의 대용물로 사용하는 것은 부적절할 것으로 보인다. The purpose of this study was to evaluate the perceived distance from home to high-voltage power lines using a transmission and substation geographic information system(TGIS). Of the 725, 136 respondents reported that high voltage power transmission tower, power lines or substation was within visual field range from home. Among them, 114 respondents reported valid address, which could be used in the analysis of TGIS. Forty two respondents(36.8 %) estimated that the power lines were closer and 15 respondents(13.2 %) estimated that they were farther than they actually were. Our current findings suggest that the reported distance from home to high-voltage power transmission towers, power lines, and substations cannot be used as a proxy for exposure to electromagnetic fields due to the low validity.
