Polonium is an element. Its isotope with mass 210 ( 210 Po) was discovered by Marie Curie and her husband Pierre Curie (shown at right) in 1898 and was later named after Marie's native land of Poland. By weight, polonium is around 5 million times more toxic than hydrogen cyanide. The main hazard is its intense radioactivity as an alpha emitter.
