In order to assess the impact of the Fukushima derived Pu isotopes on seawater, a new analytical method to rapidly determine Pu isotopes in seawater by SF-ICP-MS including Fe(OH)2 primary co-precipitation, CaF2/LaF3 secondary co-precipitation and TEVA+UTEVA+DGA extraction chromatographic separation was established. High concentration efficiency (~100%) and high U decontamination factor (~107) were achieved. The plutonium chemical recoveries were 74–88% with the mean of 83 ± 5%. The precisions for both 240Pu/239Pu atom ratios and 239+240Pu activity concentrations were less than 5% when 15 L of seawater samples with the typical 239+240Pu activity of the Northwest Pacific were measured. It just needs 12 hours to determine plutonium using this new method. The limit of detection (LOD) for 239Pu and 240Pu were both 0.08 fg/mL, corresponding to 0.01 mBq/m3 for 239Pu and 0.05 mBq/m3 for 240Pu when a 15 L volume of seawater was measured. This method was applied to determine the seawater samples collected 446–1316 km off the FDNPP accident site in the Northwest Pacific in July of 2013. The obtained 239+240Pu activity concentrations of 1.21–2.19 mBq/m3 and the 240Pu/239Pu atom ratios of 0.198–0.322 suggested that there was no significant Pu contamination from the accident to the Northwest Pacific.

“…Comparison could be made with already known samples, even if such a sample was not readily to hand because the pattern was so characteristic. 200 The technique involved the use of ICP-MS employing ID to determine the isotopic ratio of 230 Th/ 234 U. The isotopic abundance of Pb has also been used to provide information on the sample's history and/or origin.…”

“…Milling of the sample was shown not to lead to fractionation. The concentration of 230 Th in the samples was measured directly without the need for prior chemical separation. 197 The techniques SIMS, SEM and X-ray analysis were used for the analysis of uranium particles.…”

“…Because of the much higher concentration of U in different sample matrices compared with Np and Pu, a chemical separation of 237 Np and 239 Pu from U is required. This also removes most of the other interfering molecular ions and sample matrix from the samples [19][20][21]. Polyatomic interferences of 237 Np and 239 Pu on ICP-MS for environmental and human samples can result from 197 Au 40 Ar + , 199 Hg 38 Ar + , 199 Hg 40 Ar + , 200 Hg 37 Cl + , 201 Hg 36 Ar + , 201 Hg 38 Ar + , 202 Hg 37 Cl + , 204 Hg 33 S + , 204 Hg 35 Cl + , 203 Tl 34 S + , 203 Tl 36 Ar + , 205 Tl 32 S + , 205 Tl 34 S + , 204 Pb 33 S + , 204 Pb 35 Cl + , 206 Pb 31 P + , 206 Pb 33 S + , 207 Pb 32 S + , or 208 Pb 31 P + . In the event of radiological emergency, Centers for Disease Control and Prevention (CDC) is responsible for providing rapid and accurate information on the radionuclide identification and quantification, in order to direct appropriate medical treatment to people that were internally contaminated by radionuclides.…”

Measuring 237 Np and 239 Pu in urine at low levels is important for both biomonitoring and radiological emergency response. Here we report a newly developed and validated analytical method used to determine 237 Np and 239 Pu in urine by selective retention of Np and Pu from 2mL of urine directly onto TEVA® resin followed by SF-ICP-MS (coupled to a membrane desolvating introduction system) detection. The method provides solid phase extraction of Np/Pu with observed recovery ratios ranging from 89% to 113% and rapid results with limits of detection well below recommended detection guidelines for children and pregnant women (NCRP 161 reference).
