摘要
A method of calibrating an apparatus for measuring Radon and/or its progeny in an air sample, includes providing an apparatus for measuring Radon in an air sample that includes a preset offset voltage corresponding to a threshold conductivity value and a preselected reading value for indicating a concentration of Radon and/or its progeny, exposing the apparatus to a calibration area for measuring conductivity of the air therein, comparing the measured conductivity value of the air with the preset offset value for conductivity, and setting a lower threshold conductivity value and corresponding threshold reading value same as the preselected reading value, if the measured conductivity of the air is determined to be lower than the preset offset value for conductivity.
