A new method of calculating the concentration distribution of radio - nuclides was proposed , in which the effect of gravity settlement , rain washing and the decay of the radioactive species re considered 利用倾斜烟团模式，考虑实际过程中核素粒子的重力沉降、雨洗作用以及放射性衰变等因素的影响，提出一种迅速估算放射性核素扩散浓度的方法。
The paper discusses basic principle , working method and data processing of radon surveying . considering radioactive decay of radon surveying data and many disturbing factors in the actual work , we require analysis , emendation and processing actual data 本文在论述了测氡的基本原理、工作方法及数据处理的基础上，针对测氡数据放射性衰变的特点和在实际工作中受干扰因素较多等原因，要求对实测数据进行分析、校正与处理。
Abstract : from radioactive equilibrium of natural radioactive decay series and content of several radioactive constituents , the formula for estimating activity of uranium ore and solid waste is derived and a case study on treatment engineering of decommissioning linchang uranium mine is presented 文摘:根据天然放射性衰变系列的平衡关系，推出了通过若干个而非全部放射性组分的监测数据来计算铀矿石和固体废弃物中放射性活度的公式，给出了临沧铀矿退役治理工程的估算实例。
