 note = {For the 2019 PROCORAD (Association for the PROmotion of Quality COntrol in RADiotoxicological Analysis) intercomparison campaign for urine actinides analysis, we compared SF-ICP-MS and ICP-MS/MS combined with chromatographic separation using TEVA+UTEVA+DGA resins and alpha spectrometry combined with chromatographic separation using TEVA resin for the measurement of 239Pu. The Pu yields were in the range of 68–93 % (n=20). Both the methods of SF-ICP-MS (2.44±0.05 mBq/sample for 19 ACTA, n=4 and 7.63±0.13 mBq/sample for 19 ACTB, n=4) and ICP-MS/MS (2.45±0.21 mBq/sample for 19 ACTA, n=1 and 7.89±0.54 mBq/sample for 19 ACTB, n=1) presented precise and accurate results that agreed well with the assigned values (2.52±0.26 mBq/sample for 19 ACTA and 7.56±0.39 mBq/sample for 19 ACTB). The method of alpha spectrometry, showing larger uncertainties, also presented comparable results (3.49±1.29 mBq/sample for 19 ACTA, n=1 and 8.05±1.76 mBq/sample for 19 ACTB, n=1). Due to the high sensitivity of SF-ICP-MS and ICP-MS/MS, rapid determination of 239Pu (ca. 10 h) can be achieved in small volume urine sample (20 mL) generally. In contrast, the method of alpha spectrometry generally consumes more sample (e.g. 500 mL) and is more time-consuming. Therefore, it would be more feasible to measure long-lived 239Pu and 240Pu by the methods of SF-ICP-MS and ICP-MS/MS, and short-lived 238Pu by the method of alpha spectrometry for emergency response.},
