This method has high sensitivity and a wide measurement range, and is widely adopted. Ionization chamber method: The radon gas concentration in the soil is measured using the principle of an ionization chamber. Electrodes are installed inside the ionization chamber. Radon gas ionizes after entering the ionization chamber, and the radon gas concentration is determined by measuring the ionization current. Gold-silicon surface barrier detector method: Radon gas is detected using a gold-silicon surface barrier detector. This method is characterized by high precision and high sensitivity.
