摘　　要：通过使用在线监测仪在氡室中对氡子体气溶胶能谱进行测量,获取了滤纸吸附氡子体气溶胶能谱,研究了氡子体α能谱重叠的原因,找到了描述给定测量时间滤纸吸附氡子体气溶胶能谱的方法。采用离散化法处理滤纸上氡子体的累积过程,建立累积模型。该模型可以准确描述累积过程,得到给定取样时间下滤纸吸附氡子体气溶胶的累积能谱,为更准确地模拟氡子体的α粒子能谱提出了可行性方案。This article presents a technique for measuring the energy spectrum of radon progeny aerosols that are absorbed on filter paper inside a radon chamber using an online monitoring device.The study aims to investigate the factors contributing to the overlap of alpha energy spectra observed in radon progeny and proposes a method to describe the energy spectrum of radon progeny aerosols adsorbed on filter paper within a specific measurement duration.The article employs a discretization method to analyze the cumulative process of radon progeny on the filter paper and develops a cumulative model.This model accurately characterizes the cumulative process and provides the cumulative energy spectrum of radon progeny aerosols absorbed on filter paper for a given sampling time.The proposed approach offers a viable solution for more precise simulation of the alpha particle energy spectrum emitted by radon progeny.
