“…Together with their later work on isobaric interferences (Sookdeo et al . ), the authors demonstrated about five times better sensitivity than gamma and beta spectroscopy of 210 Pb and much shorter measurement times.…”

“…Hence, Sookdeo et al (2015) investigated the effect of different target compositions on the strength and stability of 208 PbF À 3 currents and 210 Pb counts. Together with their later work on isobaric interferences (Sookdeo et al 2016), the authors demonstrated about five times better sensitivity than gamma and beta spectroscopy of 210 Pb and much shorter measurement times.…”

This GGR biennial critical review covers developments and innovations in key analytical methods published since January 2014, relevant to the chemical, isotopic and crystallographic characterisation of geological and environmental materials. In nine selected analytical fields, publications considered to be of wide significance are summarised, background information is provided and their importance evaluated. In addition to instrumental technologies, this review also presents a summary of new developments in the preparation and characterisation of rock, microanalytical and isotopic reference materials, including a précis of recent changes and revisions to ISO guidelines for reference material characterisation and reporting. Selected reports are provided of isotope ratio analyses by both solution-nebulisation MC-ICP-MS and laser ablation-ICP-MS, as well as of radioactive isotope geochronology by LA-ICP-MS. Most of the analytical techniques elaborated continue to provide new applications for geochemical analysis, however it is noted that instrumental neutron activation analysis has become less popular in recent years, mostly due to the reduced availability of nuclear reactors to act as a neutron source. Many of the newer applications reported here provide analysis at increasingly finer resolution. Examples include atom probe tomography, a very sensitive method providing atomic scale information, nanoscale SIMS, for isotopic imaging of geological and biological samples, and micro-XRF, which has a spatial resolution many orders of magnitude smaller than conventional XRF

“…The possibility of employing AMS, using lead fluoride targets, to measure 210 Pb was first discussed about 20 years ago [15,16]. Most recently, the André E. Lalonde AMS Laboratory (AEL-AMS) has performed similar studies [17,18]. These have corroborated the observation that the extraction of (PbF 3 )ions from PbF 2 targets is a good choice, offering a good ionization efficiency [19,20].…”

Naturally occurring radionuclide 210 Pb (T 1/2 =22.2 y) is an important source of background in rare event searches, such as neutrinoless double-β decay and dark matter direct detection experiments. When a sample mass of hundreds of grams is available, γ-counting measurements can be performed. However, there are other cases where only grams of sample can be used. For these cases, better sensitivities are required.
