“…While the substrates that were examined in this study are commonly used for alpha spectrometry sample preparation, we did not fmd a lot of research in the literature comparing the yields and alpha particle resolutions of these substrates for suitability for alpha spectrometry. Ferrero Calabuig et al [17] examined the electrodeposition of uranium on molybdenum, nickel, stainless steel (SS), and titanium substrates using a method similar to the Hallstadius method [8]. In general, at lower thicknesses of uranium (between 0.65-21.3 11g/cm 2 ), they observed slightly improved resolution in the order Ti < SS < Mo<Ni.…”

Ultra-high resolution alpha spectrometry by microcalorimetry has demonstrated a dramatic improvement in alpha energy resolution over silicon based detectors. To characterize the optimal resolution obtained by the microcalorimeter alpha spectrometers, high quality deposits that are virtually massless are required; electrodeposition is the preferred method for the preparation of high quality deposits. In order to better understand the factors that contribute to lower alpha energy resolution and deposit yield, we have conducted a study to determine the effect of some of the parameters that are used for preparing electrodeposits. We have compared four different electrodeposition methods and four different substrate materials to determine the effect on the deposit yield and alpha energy resolution of plutonium as measured by full width at half maximum (FWHM) using silicon based detectors. Furthermore, we wanted to understand the effect of sample contaminants from environmental samples on electrodeposits. Therefore, the effect on deposit yield and alpha energy resolution with several common soil constituents

“…Conventional secondary ion mass spectrometry (SIMS) systems equipped with ion beam depeth profiling also can achieve namometer depth resolution for the alphaemitting radionuclides electrodeposited layer, together with a high level of detection and quantification [126]. In addition to XPS and SIMS, Rutherford backscattering spectroscopy (RBS) and glow discharge optical emission spectroscopy (GDOES) have been widely used to carry out the depthptofiling characterization [125,[127][128][129].…”

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.
