The “ventilation chamber” technique is unreplaceable when the radon exhalation rate is surveyed continuously. The air pressure difference between the chamber and the environment that leads the increase of radon exhalation rate can be reduced by increasing the diameter of the air input tube. A sufficient condition for a standard measurement is the air change rate has to be far larger than the effective decay constant in the measurement. When the sufficient condition is false, the measured value of the radon exhalation rate from the custom mode...
