as the soil radon exhalation have an important impact on the indoor radon concentration, the research of soil radon exhalation is caused by a new hotspot.
土壤氡析出率的影响因素很多,其中大气压力是较为重要的影响因素之一。
the only input factors of the simplified model were soil radium content, dry bulk density, water content and soil texture type and the output was soil radon exhalation rate.
