본 연구에서는 대전광역시 실내 라돈의 농도 분포를 조사하고 라돈 저감 공법을 적용하여 저감 효율을 평가하였다. 전국주택라돈조사 결과를 기초로 선별된 24개 주택을 대상으로 실내 라돈 측정을 실시한결과, A자치구의 평균치가 261 Bq/m3 로서 기준치를 크게 상회하는 수준임을 알 수 있었고, 동일한 주택에서도 실내 라돈 농도는 측정 지점과 시간에 따라 영향을 받고 있음을 확인하였다. 라돈 저감을 위해 토양배기법을 적용한 8개 주택의 경우, 실내 라돈 수치는 기준치에 비해 크게 낮아졌으며 평균 저감 효율 역시55% 정도로 나타나 양호한 라돈 저감 효과를 알 수 있었다. 또한 차폐법을 실시한 2개의 주택에서는 평균저감 효율이 90% 정도로서 실내 라돈 저감 효과가 매우 우수하였다. 라돈 저감 시 동일한 저감공법을 적용하여도 건물의 구조, 환기의 빈도, 계절 등 여러 요인에 따라 저감 효율이 달라질 수 있으므로 향후 다양한인자를 반영하여 저감공법의 효과를 정밀하게 평가할 필요가 있다. 이를 기초로 하여 라돈 노출에 의한 인체 위해 저감을 위한 대전광역시 실내 라돈 관리 대책 마련이 필요하다.
Abstract
In this study, the concentration distribution of indoor radon in Daejeon Metropolitan City was investigated and the reduction efficiency was evaluated by applying the radon reduction methods. Based on the results of the National Institute of Environmental Research, indoor radon measurements were conducted on 24 selected houses, and the average value of District A was 261 Bq/m3, far exceeding the standard, and even in the same house, indoor radon concentration was affected by measurement point and time. In the case of eight houses that applied the soil venting method to reduce radon, the indoorradon level was significantly lowerthan the standard value, and the average reduction efficiency was also around 55%, indicating a good reduction effect. In addition, the average reduction efficiency was around 90% in the two houses that carried out the shielding method, showing the very excellent effect of the indoorradon reduction. Even if the same reduction method is applied when reducing radon, the reduction efficiency may vary depending on various factors such as the structure of the building, the frequency of ventilation, and the season, so it is necessary to accurately evaluate the effectiveness of the reduction method in the future. Based on this, it is necessary to establish indoor radon management measures in Daejeon Metropolitan City to reduce human harm caused by radon exposure.
