建筑装饰材料放射性污染浓度在线监测方法研究
|
摘要
目前测量建筑装饰材料放射性污染浓度方法容易受到外界干扰,造成数据精确度不足,鲁棒性较差。以菲克定律为核心,分析建筑装饰材料放射性污染物释放原理;根据放射性污染物释放的不同状态,计算动态和静态释放速率;结合菲克第二定律与释放速率,计算表面层释放放射性污染物浓度和结合层释放放射性污染物浓度;完成放射性浓度在线监测方法。在使用不同建筑装饰材料监测情况下,放射性污染浓度在线监测方法监测数据没有受到影响,该方法鲁棒性优于传统监测方法,适合应用在建筑装饰材料放射性污染浓度监测中。
At present,the method of measuring the radioactive pollution concentration of building decoration materials is easily interfered and the data is not accurate enough. The method of online monitoring radioactive pollution concentration of building decoration materials is put forward. With Fick's law as the core,the design method assumes the conditions; dynamic and static release rates were calculated according to different release states of radioactive pollutants. Combined with Fick's second law and release rate,the concentration of radioactive pollutants released by surface layer and the concentration of radioactive pollutants released by binding layer were calculated. Complete the method of online radioactive concentration monitoring. The experimental results show that the data measured by the online monitoring method of radioactive pollution concentration are not affected under different radioactive materials,and the robustness of the method is better than that of the traditional monitoring method,which is suitable for the monitoring of radioactive pollution concentration of building decoration materials.
