E-PERM radon monitors are based on the principle of electret ion chambers and are usually calibrated in a standard radon chamber located at sea level. Corrections are needed if the monitors are used at elevations other than sea level. These were experimentally determined for three models of commercially available electret ion chambers (E-PERM) as functions of elevation above sea level. These corrections are minor and should be applied for obtaining more accurate results.
E-PERM氡监测仪基于驻极体电离室原理，通常在海平面的标准氡室内进行校准。如果监测仪在海平面以外的海拔高度使用，则需要进行校正。已针对三种市售驻极体电离室（E-PERM）模型通过实验确定了这些校正值，它们是海平面以上海拔高度的函数。这些校正值较小，为获得更准确的结果应予以应用。
