A sensitive method to determine 210Po and 210Pb in environmental samples by alpha spectrometry using CuS micro-precipitation [PDF]
Scientific Reports, 2023 A new sensitive method to determine polonium-210 (210Po) and lead-210 (210Pb) in a diversity of environmental samples was developed. For fresh and marine waters, Po was pre-concentrated using a titanium (III) hydroxide (Ti(OH)3) co-precipitation.

Preparation of Standard Plane Source of 210Po
Journal of Isotopes, 2021 A method of spontaneous deposition of 210Po on a silver disc was used to prepare the standard plane source in a 210Pb solution. The prepared source was measured by an alpha spectrometer.

Multi-Physics Model Development for Polonium Transport Behavior in a Lead-Cooled Fast Reactor
Frontiers in Energy Research, 2021 210Po, a highly toxic element with strong volatility, is one of the main source terms of a Gen-IV lead-cooled fast reactor (LFR). Therefore, the radioactive safety caused by 210Po has become an important topic in LFR-related research.

210Po/210Pb Disequilibria in the Eastern Tropical North Pacific
Frontiers in Marine Science, 2021 The 210Po/210Pb disequilibrium was attempted to reveal the small-scale particle dynamics in the eastern tropical North Pacific. Seawater samples in the full water column were collected from three sites in the Tehuantepec bowl near the East Pacific Ridge ...
