Polonium is the heaviest element in the chalcogen family. Se hela listan på b2b.partcommunity.com Polonium-210 is a very strong emitter of alpha particles. A single gram of polonium-210 creates 140 Watts of heat energy and is being considered as a lightweight heat source for thermoelectric power for spacecraft. Polonium-210 has a half-life of 138.39 days. Polonium's most stable isotope, polonium-209, has a half-life of 102 years.

Polonium (84 Po) has 42 isotopes, all of which are radioactive, with between 186 and 227 nucleons. 210 Po with a half-life of 138.376 days has the longest half-life of naturally occurring polonium. 209 Po, with a half-life of 125.2 years, has the longest half-life of all isotopes of polonium. 209 Po and 208 Po (half-life 2.9 years) can be made through proton bombardment of bismuth in a cyclotron. Polonium-210 was used to kill Russian dissident and ex-FSB officer Alexander V. Litvinenko in 2006, and was suspected as a possible cause of Yasser Arafat's death, following exhumation and analysis of his corpse in 2012–2013. Po-210 is used in some industrial applications such as static eliminators, which are devices designed to eliminate static electricity in processes such as rolling paper, manufacturing sheet plastics, and spinning synthetic fibers.

Most of this polonium is derived from lead-210 deposited on tobacco leaves from the atmosphere; the lead-210 is a product of radon-222 gas, much of which appears to originate from the decay of radium-226 from fertilizers applied to the tobacco soils. Subscribe to our channel http://bit.ly/AJSubscribeThe final report from the Institute of Radiophysics in Lausanne, Switzerland, found abnormal levels of radi 2013-11-07 · Polonium is a metal found in uranium ore whose isotope polonium-210 is highly radioactive, emitting tiny positively charged alpha particles. So long as polonium is kept out of the human body, It is believed that an ex-KGB agent placed poloinium-210 in Litveninko's tea. It took about three weeks to kill Litvinenko, and during that time his immune system shut down, he lost his hair, and In nature, polonium-210 is the most common isotope of polonium.
