“…While quantification would be challenging, using this approach it may be adequate for rapid screening applications where the presence of a particular isotope may target that sample for further more rigorous analysis. For ˛-spectrometry we used the ICP-MS to implant trace levels of 241 Am and compared the ˛-energy spectrum with those produced by the standard methods of ˛-sample preparation of electro-deposition and direct solution stippling [19][20][21]. The ICP-MS implanted 241 Am ˛-spectrum displayed considerable improvement in energy resolution compared to samples with similar levels of activity produced using the two conventional methods highlighted.…”

a b s t r a c tWe report the development and testing of a collector arrangement for quadrupole inductively coupled plasma mass spectrometry (ICP-MS) that for the first time has been used to isolate small quantities of highly enriched (>99.99%) single isotopes, with deposition rates >10 ng h −1 . The collector assembly replaces the standard instrument detector allowing for implantation with simultaneous monitoring of the incident ion current. Even under zero bias implant conditions, low energy (<10 eV) ion collection efficiency was observed to be very high 99%. 151 Eu ion currents of 0.1-0.5 nA were collected on a simple, planar foil without resorting to any type of cup configuration. Recovery of the enriched isotope from such foils is much simpler than from a more complex cup configuration. High rejection of adjacent mass isotopes was demonstrated by selectively implanting 167 Er, then using laser ablation ICP-MS imaging to confirm the absence of any co-implanted 166 Er or 168 Er. The important analytical possibilities of this new approach to isotope ratio measurement, tracer purification, and radiation measurements are discussed.

“…High temperature may have both positive and negative influence on the electrodeposition yield owing to changes of pH and ion mobility of an electrolyte solution [88]. To reduce the effect of the solution temperature, the electrodeposition cell is sometimes immersed into a temperature-controlled water bath during the electrodeposition process [102].…”

“…Many researches have been reported to find a suitable alpha source by the adjustment of a surface mass density in the range of 15-250 μg/cm 2 with mirror polished stainless steel discs of 2.0 or 2.2 cm diameter of active area [111,112]. Jobbágy et al reported that the surface mass density should be kept below 26 μg/cm 2 with 2.0 cm diameter of active area for uranium in order to obtain both high energy resolution and good counting statistics [113]. However, in order to apply to various radionuclides, much more research needs to be carried out.…”

In various methods to determine alpha-emitting radionuclides in matrices, alpha-particle spectrometry with alpha-emitting sources prepared by the electrodeposition has been widely used. Although there are several good review papers on alphaparticle spectrometry and preparation of electrodeposited alpha-emitting sources, the mechanism of analysis procedure and characterizations of alpha-emitting sources have not been reported well. These untouched subjects by other review papers are very significant to improve the analysis procedure. This review focuses on the mechanism of the electrodeposition of alpha-emitting radionuclides on the stainless steel disc, factors for the preparation of electrodeposited alpha-emitting layers, and various characterization methods.

“…However, many trial tests had to be performed to find the ideal conditions, which involves many free parameters such as source diameter, thickness, electrolyte (composition, pH, temperature), anode (material, rotation and geometry), purity of materials, current homogeneity, substrate surface roughness, calcination of source, etc. The different parameters tested at IRMM and CIEMAT have been described in detail by Jobbágy et al [4].…”

Nuclear decay data measurements were performed in the frame of a EURAMET project. Two specific goals were addressed: (1) High-precision measurements of 238 U alphaparticle emission probabilities and (2) experimental characterization of the shape of beta spectra using cryogenic detectors. In the paper, specific lessons learned from the metrological work are highlighted. This includes effects of source preparation on the quality of alpha and beta spectrometry, the influence of exchange effects on beta spectra and the use of a magnet system to eliminate coincidence effects by conversion electrons in alpha-particle spectra.
