本文给出我国5个铀矿1988－1993年间共20657个井下氡浓度监测数据的统计结果。结果表明，平均氡浓度范围为2664－13246Bqm－3，氡浓度超过3000Bqm－3的占54％，平衡因子F值约为0．33。
This paper gives the statistics of 20657 underground radon concentration monitoring data of five uranium mines in China from 1988 to 1993. The results show that the average radon concentration range of 2664-13246Bqm-3, radon concentration of more than 3000Bqm-3 accounted for 54%, the balance factor F value of about 0.33.
