In this study, we reviewed the Reference Materials (RMs) of Pu and prepared extensive Pu isotope ratio datasets in order to quickly and reliably select the suitable RM for validating the determination of plutonium (Pu) isotopes. After data treatment and a series of statistical analyses, we obtained the statistical values Pu isotopic ratios for RMs. We anticipate that, after further independent work at different laboratories, the statistical values of the Pu isotopic ratios are very important to validate analysis methods and calibrate the mass bias for environmental Pu analysis.
