摘要:
The open-loop method of measuring soil radon exhalation rate is widely used to explore the influence of environmental factors on soil radon exhalation rate because it can continuously monitor and quickly respond to changes in soil radon exhalation rate. However, in the open-loop measurement, the ventilation chamber is connected to the outside environment, and under the action of the pump, the ventilation chamber will have a certain suction effect on the covered soil surface. When the soil is relatively dry, there may be some tiny cracks on the soil surface. Under the influence of suction, the ...
