“…The second strategy relies on the complete removal of the 241 Am in the 241 Pu material and setting the "clock" to zero (time zero). The amount of produced 241 Am by beta decay of 241 Pu (half-life 14.325 (24) years, k = 2 [18]) can be calculated at a given time using the appropriate Bateman equation [10]. The concentration of 241 Pu in the purified solution is determined by reverse IDMS using a certified plutonium spike CRM.…”

The Joint Research Centre, in cooperation with the Commissariat à l’Energie Atomique et aux Energies Alternatives, produced a novel 243Am spike reference material for mass spectrometry. Americium solution with an isotopic composition of 88% 243Am and 12% 241Am was used as the source for the preparation of the spike material. The certified value of 5.696 (11) nmol g−1 for the amount content of 243Am and 0.136138 (54) for the n(241Am)/n(243Am) amount ratio were assigned. The assigned values from mass spectrometry were confirmed by alpha-particle spectrometry, alpha-particle counting at a defined solid angle, and high-resolution gamma-ray spectrometry. Furthermore, an external validation of the certified values was obtained from the results of an interlaboratory comparison exercise, using this americium reference solution as the test sample.

“…Prior to the isotope ratio measurements, two purification steps were carried out to remove the 241 Pu from the in-grown 241 Am in the blends by means of UTEVA-spec [23] and DGA extraction resins [24] (both of Triskem International, Bruz, France). The time of the Am elution (i.e.…”

“…AMS was also used recently to determine the ultra‐trace amounts of 241 Am in sediment and soil samples (Kazi et al, ). A single‐step DGA resin (normal: N,N,N′,N′‐tetra‐n‐octyldiglycolamide) extraction chromatography column was used to separate Pu and 241 Am from the sediment samples.…”

The manuscript reviews the various mass spectrometric techniques for analysis and chemical studies of Americium. These methods include thermal ionization mass spectrometry (TIMS), and inductively coupled plasma source mass spectrometry (ICPMS) for the determination of Am isotope ratios and concentration in nuclear fuel samples of interest in nuclear technology, and in complex biological and environmental samples. Ultra-sensitive mass spectrometric techniques of resonance-ionization mass spectrometry (RIMS), and accelerator-based mass spectrometry (AMS) are also discussed. The novel applications of electrospray ionization mass spectrometry (ESIMS) to understand the solution chemistry of Am and other actinides are presented. These studies are important in view of the world-wide efforts to develop novel complexing agents to separate lanthanides and minor actinides (Am, Np, and Cm) for partitioning and transmutation of minor actinides from the point of view of nuclear waste management. These mass spectrometry experiments are also of great interest to examine the covalent character of actinides with increasing atomic number. Studies on gas-phase chemistry of Am and its oxides with Knudsen effusion mass spectrometry (KEMS), Fourier-transform ion cyclotron resonance mass spectrometry (FTICR-MS), and laser-based experiments with reflectron time-of-flight mass spectrometer (R-ToF) are highlighted. These studies are important to understand the fundamental chemistry of 5f electrons in actinides. Requirement of certified isotopic reference materials of Am to improve the accuracy of experimental nuclear data (e.g., the half-life of Am) is emphasized. © 2016 Wiley Periodicals, Inc.

“…Also, the presence of high salt content would create a deposit that would lead to loss of the energy of some alpha particles leading to a low energy tailing of the characteristic alpha energy peaks in the spectrum. Another method for alpha source preparation is microcoprecipitation of actinides with rare-earth fluoride like NdF 3 , and filtration deposition on smooth surface membrane having 0.1-0.2 mm pore size [1,11,12]. However, the most common method used for alpha spectrometry is the electrodeposition of actinides onto a polished metal (stainless-steel, silver, copper, nickel or platinum) cathode planchette/disc [13].…”
