Abstract Objective To test the capability of soil 90Sr analysis, and to improve the measuring level and data accuracy for each laboratory.Methods Organize an intercomparison experiment of soil 90Sr analysis among the nationwide radiation environment monitoring laboratories.Results Twenty laboratories participated in the intercomparison, the results of 80% laboratories are acceptable, while 20% are unacceptable.Conclusion The overall result was fine. Problems found in the intercomparison need future research.
