210Po sequential extraction applied to wetland soils at uranium mining sites

Geometries, interaction energies and bonding in [Po(H2O)n]4+ and [PoCln]4−n complexes

“…While most of polonium chemistry remains unknown, its extreme toxicity, being either chemical or radiological, is notorious. 1,2 Though its radioactivity may be used to detect it, it is still complicated to perform analyses to determine polonium traces in, for example, sea water, 3 tobacco, 4,5 plants, 6 soils 7 and other samples. Meanwhile, former usages of polonium as a heat source in the space machine industry, as an α-emission source, or as static eliminators have now become obsolete because of alternatives based on materials that are safer and easier to obtain.…”

Virus-to-prokaryote ratio in spring waters along a gradient of natural radioactivity

“…Pb and Bi-based polyatomic interferences unresolved in low and medium resolution modes were not considered in the present study due to low signal intensities measured for Pb (< 60,000 CPS) and Bi (< 1 000 CPS). Finally, 210 Po was measured, after spontaneous deposition onto a silver disc, by alpha spectrometry using dual alpha spectrometers EG&G Ortec 576A equipped with boron-implanted silicon detectors (Le et al, 2019).…”
