【Abstract】 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.更多还原
