- Polonium is a rare element with 33 radioisotopes. The most common one, P210o, has 84 protons and 126 neutrons. When P210o decays, it emits an alpha particle, which is a helium nucleus 2 protons and 2 neutrons. P210o decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. For example, they can be stopped by a single sheet of paper or a few inches of air. That is one reason why authorities failed to discover toxic amounts of P210o in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006.
