(1) A radioactive metallic element that is similar to tellurium and bismuth; occurs in uranium ores but can be produced by bombarding bismuth with neutrons in a nuclear reactor

(1) This generator is a small pellet of polonium and beryllium, separated by foil within the fissionable fuel core.
(2) Gentry had discovered that granites contain microscopic coloration halos produced by the radioactive decay of primordial polonium .
(3) Radon can enter the body through the lungs, where it undergoes alpha decay to form polonium , a radioactive solid that remains in the lungs and continues to emit cancer-causing radiation.
(4) In the process, she discovered two new elements that are millions and billions of times more radioactive than uranium: radium and polonium .
(5) The uranium eventually decays to radium and, eventually to polonium -210, a substance that, when inhaled, can endanger tissue health and damage the immune system.
