Abstract Objective To summarize the long-term experience of radioanalysis and solve the current practical problems encountered in the rare earth radioanalysis.Methods Make comparison study by comparing different measurement methods and sample passing analysis between the laboratories.ResultsThe correct selection of standard reference matter is the guarantee of the accuracy of the analysis;γspectrum analysis is the guarantee of rare earth radioanalysis.But as of the non radio-balance samples, other analysis methods should be used simultaneously to get more information from the samples.Conclusion As of some complicated, unknown samples, it is very necessary to make comparison study regularly so as to improve the level of analysis and measurement, and make full use of the national open laboratories.
