本文概括地介绍了采用测量累积氡浓度的固体径迹图像分析方法。在一些住宅和地下空间内布放ＣＲ－３９固体径迹探测器，对氡浓度进行了测量，对所测结果进行了评价，并针对实际情况采取了降低氡浓度的防护措施。
This article provides an overview of solid-track image analysis methods that measure cumulative radon concentrations. In some residential and underground space, CR-39 solid track detector was placed to measure the radon concentration. The measured results were evaluated and protective measures to reduce the radon concentration were taken according to the actual situation.
