Polonium is studied in a few nuclear research laboratories where its high radioactivity as an alpha-emitter requires special handling This forms radioactive bismuth-210, which has a half-life of five days. Bismuth- 210 decays to polonium-210 through beta decay. Milligram amounts of polonium- Polonium is a radioactive element that exists in two metallic allotropes.

A famous example is the poisoning of Alexander Litvinenko, who took 3 weeks to die Unlike most common radiation sources, polonium-210 emits very little gamma radiation (the low intensity gamma ray at an energy of 803 keV is the most prominent), but large amounts of alpha particles which do not penetrate even a sheet of paper or the epidermis of human skin, and is therefore relatively invisible to common radiation detectors such as Geiger counters.

2019-12-18 · Polonium is a radioactive chemical element that has no stable isotopes. In its chemical properties, polonium is similar to selenium and tellurium. Due to high radioactivity and ability to perform radiolysis and break down the chemical bonds, experiments regarding polonium have been conducted only for trace amounts of polonium. As a British inquiry finds Russian President Vladimir Putin "probably" approved the assassination of spy-turned-dissident Alexander Litvinenko, take a look at polonium-210, the rare, radioactive Polonium, a radioactive, silvery-gray or black metallic element of the oxygen group (Group 16 [VIa] in the periodic table).
