Polonium-210 ( Po, Po-210, historically radium F) is an isotope of polonium. It undergoes alpha decay to stable Pb with a half-life of 138.376 days (about 4+1⁄2 months), the longest half-life of all naturally occurring polonium isotopes. First identified in 1898, and also marking the discovery of the element polonium, Po is generated in the decay chain of uranium-238 and radium-226. Po is a prominent contaminant in the environment, mostly affecting seafood and tobacco. Its extreme tox…

Polonium – Wikipedia Polonium Polonium är ett radioaktivt metalliskt sällsynt grundämne. Polonium är kraftigt alfastrålande och används därför som strålkälla. De flesta poloniumisotoper är kortlivade stadier i sönderfallskedjor för tyngre ämnen.

Polonium – Wikipedia Polonium Polonium ( lat. polonium) on alkuaine, jonka kemiallinen merkki on Po ja järjestysluku 84 sekä CAS-numero 7440-08-6. Se on radioaktiivinen puolimetalli, joka nimettiin löytäjänsä Marie Curien syntymämaan Puolan mukaan. Curie löysi poloniumin vuonna 1898 tutkiessaan Joachimsthalin uraniniitin radioaktiivisuutta.

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 …

From Wikipedia, the free encyclopedia Polonium dioxide (also known as polonium (IV) oxide) is a chemical compound with the formula Po O 2. It is one of three oxides of polonium, the other two being polonium monoxide (PoO) and polonium trioxide (PoO 3 ). It is a pale yellow crystalline solid at room temperature.
