摘要：
We propose a novel method for quickly measuring the radon exhalation rate in open loop. We first obtain the temporal variation of radon concentration in the internal cell of the RAD7 by analyzing the work principle of RAD7. We then obtain the temporal variation of radon concentration in the ventilation-type accumulation chamber when the effects of leakage and back diffusion are neglected. This method uses the measured value before the radon concentration in the ventilation-type accumulation chamber reaches a steady state. The diameter of the air input tube to the ventilation-type accumulation ...
