Reexamination of nuclear magnetic dipole and electric quadrupole moments of polonium isotopes

Physical Review C, 2023
We revisited the electronic structure parameters used to interpret the hyperfine structure of neutral polonium. We used a computational scheme that treats relativistic and high-order electronic correlation effects within the coupled cluster with single ...

Determination of polonium-210 in environmental samples using diglycolamide-based cloud point extraction coupled to alpha spectrometry analysis.

Applied Radiation and Isotopes, 2020
This study presents a novel cloud point extraction (CPE) methodology for the separation and enrichment of polonium-210 prior to alpha-spectrometric quantification in water, urine and digested samples.

The aqueous chemistry of polonium (Po) in environmental and anthropogenic processes.

Journal of Hazardous Materials, 2019
The longest-lived naturally occurring isotope of polonium is polonium-210, one of the daughters of uranium-238 (138 days half-life). As a daughter radionuclide of radon-222, polonium-210 can become enriched in pore fluids in U-bearing rocks, leading to ...

Spatial variability in Polonium-210 and Lead-210 activity concentration in New Zealand shellfish and dose assessment.

Journal of Environmental Radioactivity, 2019
The activity concentrations of Polonium-210 (210Po) and Lead-210 (210Pb) were determined in shellfish (Perna canaliculus and Paphies subtriangulata) sampled bimonthly from March 2018 to February 2019 from 14 sites around New Zealand.

Rousing the dragon: Polonium production for neutron generators in the Manhattan Project

American Journal of Physics, 2019
During the Manhattan Project, the rare element polonium (Po) was synthesized by neutron bombardment of bismuth in nuclear reactors for use in neutron-generating triggers that were used to initiate the fission chain reactions in the Hiroshima and Nagasaki
