Abstract Objective To explore relevant factors about the soil radon measurement and provide gist of formulating correct measure method by studying the way of the soil radon measurement.Methods Deflation-ionization room standard is adopted.Results The concentration of soil radon becomes higher with the sample's volume added, it also augmented with the measure depth increased in certain degree;The concentration of soil radon changes little when sample's depth is above 60cm;The time of deflation has no obvious influence on the concentration of soil radon, but microwave show serious effect on it;The results will be lowered when the desiccant is humidified, raining has the same affection on it;Plant has some impact on it.Conclusion The measured results will be affected by microwave, oscillate and plant.Sample's volume and depth, soil's humidity can influence it too.The result's veracity can be guaranteed by choosing appropriate sample and measure condition.
