气溶胶对氡室氡浓度影响的探讨

Influence of Aerosol Upon Radon Concentration of Radon Chamber

通过实验测试往氡室中充入气溶胶对氡室氡浓度的影响,及测试在不同氡浓度及气溶胶浓度的条件下气溶胶对氡子体的吸附。实验结果显示:气溶胶对氡室氡浓度的稳定性没有影响,不同气溶胶浓度则会改变氡子体的结合状态,从而影响氡子体的扩散系数,所以会影响总量测量仪的测量结果。

On the basis of theoretical analysis,the influence on the radon concentration of radon chamber by the experiment of filling the radon chamber with aerosol,and the absorption of radon daughter on aerosol under the condition of different radon concentration and aerosol concentration was described.The results of experiment showed that：Aerosol did not affect the stability of the radon concentration of the radon chamber,but different aerosol concentration will change the combination state of radon daughter,thus it will affect the diffusion coefficient of radon daughter,so it will affect the results of the measure of the gross measuring instrument.
