Polonium is a rare element with 33 radioisotopes. The most common one, 210Po, has 84 protons and 126 neutrons. When 210Po decays, it emits an alpha particle. 210Po decay is tricky to detect because alpha particles carry very little radiation. They can be stopped by only a sheet of paper or a few inches of air. That is one reason that authorities failed to discovered toxic amounts of 210Po in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of 210Po change into after it emits an alpha particle?
