摘　　要：氡是一种天然存在的放射性气体,分别来自锕系衰变、钍系衰变和铀系衰变,而锕系、钍系和铀系元素在地壳中广泛存在。随着聚丙烯产品应用越来越广泛,其原料也从传统的石油扩展到煤到天然气。当氡气混合到天然气中,对聚丙烯工艺中应用的电离辐射仪表不可避免的产生干扰,本文结合实际工作中的情况对此问题进行了初步的探讨与分析。Radon is a naturally occurring radioactive gas, respectively from the actinide decay, thorium decay and uranium decays, and actinides, thorium and uranium element in the earth＇s crust is widespread. As polypropylene product application more and more widely, its raw materials from the traditional oil also extend from coal to gas. When mixed into natural gas, radon gas ionizing radiation instrument on the application of the polypropylene process inevitably produce interference. This paper combining with actual work in the case of the second question carries on the preliminary discussion and analysis.
