| 摘 要： | 活性炭具有较强的吸氡能力，利用该特性可实现局部空间降氡的目的。本文研究了活性炭局部降氡实际应用中最大降氡效率与活性炭吸附系数、活性炭质量、空间体积、环境温度及湿度等的关系，建立了计算活性炭局部降氡效率的理论模型，并通过菲律宾产4×8目和12×20目两种粒径的活性炭对理论模型进行了实验验证。结果表明，理论值和实测值的一致性较好，相对偏差均在±4.7%以内。

| Abstract: | Active carbon can decrease radon in local room because of its good capability with absorbing radon.The relations of the biggest decreasing radon efficiency with absorb coefficient,mass,volume of room,temperature,and humidity were studied.A theoretical model of decreasing radon efficiency by active carbon was established and verified with two sizes(4×8 mesh and 12×20 mesh) Philippine active carbon by the experiments.The result shows that the relative difference between theoretical value and measuring value is in ±4.7%. |
