Hydrogen bonding with polonium
Physical Chemistry Chemical Physics, 2022Beyond atomic electronegativity: polonium can form hydrogen bonds even if its electronegativity is less than that of hydrogen. The X–H⋯Po H-bonds are dominated by dispersion and can have H-bond energy comparable to that of conventional H-bonds.

Publisher Summary The heaviest elements in every group of the Periodic Table have a special interest because of the marked change in the properties, which occurs in passing down a group, thus, in the heaviest member, the maximum group valency is achieved with difficulty, if at all.

Journal of Radiological Protection, 2007
The death of Alexander Litvinenko on 23 November 2006 has brought into focus scientific judgements concerning the radiotoxicity of polonium-210 ((210)Po). This paper does not consider the specific radiological circumstances surrounding the tragic death of Mr Litvinenko; rather, it provides an evaluation of published human and animal data and models ...

Journal of Occupational and Environmental Medicine, 1965
The part played by polonium-210 in contributing to the biologically effective radiation dose received by humans in a variety of environments is described. The selection of data presented has been dictated to a large extent by the availability of post-mortem and other specimens and cannot be considered comprehensive.

The Physical Properties of Polonium. III. The Half-Life of Polonium
The Journal of Chemical Physics, 1949The half-life of polonium has been measured by a calorimetric method. The reproducibility and precision of the data is much greater than has been previously reported. The value is found to be 138.3±0.1 percent days.
