“…If the ICP-MS/MS is equipped with an APEX-Q high-efficiency sample introduction system, the detection limit could be improved to 0.1 fg mL -1 for 239 Pu and 0.02 fg mL -1 for 240 Pu. The analytical results of reference materials show that the measured activity concentration of 239 Pu and 240 Pu and are 1.81±0.07 mBq g -1 and 1.17±0.10 mBq g -1 in the IAEA-385 and 0.37±0.01 mBq g -1 and 0.23±0.01 mBq g -1 in the IAEA-412, respectively (Table 2), which are in a good agreement with the certified values of 1.79±0.28 mBq g -1 and 1.15±0.14 mBq g -1 of IAEA-385 [37] and 0.36±0.016 mBq g -1 and 0.24±0.016 mBq g -1 of IAEA-412 [38], respectively. All these features prove that the developed method for determination of low level 239 Pu and 240 Pu in the environmental samples is reliable and accurate.…”

In order to measure trace plutonium and its isotopes ratio (Pu/Pu) in environmental samples with a high uranium, an analytical method was developed using radiochemical separation for separation of plutonium from matrix and interfering elements including most of uranium and ICP-MS for measurement of plutonium isotopes. A novel measurement method was established for extensively removing the isobaric interference from uranium (UH and UH) and tailing of U, but significantly improving the measurement sensitivity of plutonium isotopes by employing NH/He as collision/reaction cell gases and MS/MS system in the triple quadrupole ICP-MS instrument. The results show that removal efficiency of uranium interference was improved by more than 15 times, and the sensitivity of plutonium isotopes was increased by a factor of more than 3 compared to the conventional ICP-MS. The mechanism on the effective suppress of U interference forPu measurement using NH-He reaction gases was explored to be the formation of UNH and UNH in the reactions of UH and U with NH, while no reaction between NH and Pu. The detection limits of this method were estimated to be 0.55 fg mL for Pu, 0.09 fg mL for Pu. The analytical precision and accuracy of the method for Pu isotopes concentration andPu/Pu atomic ratio were evaluated by analysis of sediment reference materials (IAEA-385 and IAEA-412) with different levels of plutonium and uranium. The developed method were successfully applied to determine Pu andPu concentrations and Pu/Pu atomic ratios in soil samples collected in coastal areas of eastern China.

“…Although the 240 Pu/ 239 Pu atom ratios are not certified, the ratios obtained for the reference samples (Table 4) agree with other reported values using various analytical techniques such as ICP-MS, accelerator mass spectrometry, thermal ionisation mass spectrometry and high-resolution ␣-spectrometry [6,19,[27][28][29]32,[35][36][37][38][39][40][41][42][43][44][45][46]. The precisions (n = 10) of the measurements ranged from 1.7% to 8.6% depending on the total Pu concentrations in the samples.…”

Results of nondestructive gamma-ray analyses of cosmogenic radionuclides ( 7 Be, 22 Na, 26 Al, 46 Sc, 48 V, 54 Mn, 56 Co, 57 Co, 58 Co, and 60 Co) in 19 fragments of the Ko sice meteorite are presented and discussed. The activities varied mainly with position of fragments in the meteoroid body, and with fluxes of cosmic-ray particles in the space affecting radionuclides with different half-lives. Monte Carlo simulations of the production rates of 60 Co and 26 Al compared with experimental data indicate that the pre-atmospheric radius of the meteoroid was 50 AE 5 cm. In two Ko sice fragments, He, Ne, and Ar concentrations and isotopic compositions were also analyzed. The noble-gas cosmic-ray exposure age of the Ko sice meteorite is 5-7 Myr, consistent with the conspicuous peak (or doublet peak) in the exposure age histogram of H chondrites. One sample likely contains traces of implanted solar wind Ne, suggesting that Ko sice is a regolith breccia. The agreement between the simulated and observed 26 Al activities indicate that the meteoroid was mostly irradiated by a long-term average flux of galactic cosmic rays of 4.8 particles cm À2 s À1 , whereas the short-lived radionuclide activities are more consistent with a flux of 7.0 protons cm À2 s À1 as a result of the low solar modulation of the galactic cosmic rays during the last few years before the meteorite fall.
