建筑场地土壤氡浓度检测影响因素分析

Analysis of the Influencing Factors of Soil Radon Concentration Detection in Building Sites

摘要: 在建筑场地土壤氡浓度检测过程中会遇到同一个测试人员对同一个地块测出的检测结果截然不同或者不同时期检测同一个采样点检测结果差别很大等诸类问题。据不少同行反映，土壤氡浓度最终的检测结果并不精确。本文从多角度分析影响土壤氡浓度检测结果的因素，从而得到客观、正确的评价。简单介绍准备工作、数据的处理、异常点上的处理，重点介绍七大影响因素。试图找出影响土壤氡浓度测定结果准确性的相关因素，以期为提高建筑场地土壤氡浓度检测准确性奠定研究基础。该文工作对从事土壤中氡气浓度检测人员对异常值的分析和以后对《民用建筑工程室内环境污染控制标准》GB 50325-2020修订具有参考意义。

Abstract: In the process of soil radon concentration detection on construction sites, there will encounter problems such as the same test results on the same plot or the different test results of the same sampling site are very different in different periods. According to many peers, the final detection results of soil radon concentration are not accurate. This paper analyzes the factors affecting the detection results of soil radon concentration from multiple angles, thus obtaining an objective and correct evaluation. Based on the corrected introduction of the preparation work, data processing, the processing of anomalies, focusing on the seven influencing factors, we try to identify the factors affecting the accuracy of soil radon concentration measurement results, in order to improve the accuracy of soil radon concentration detection in building sites. This work is of reference significance for the analysis of outliers by personnel engaged in radon gas concentration detection in soil and the later revision of GB 50325-2020 of the Indoor Environmental Pollution Control Standard for Civil Construction Engineering.
