A Matter of Elemental Facts: Polonium - continuum
Today, polonium is usually produced in milligram quantities by the neutron irradiation of bismuth. Due to its intense radioactivity, which results in the radiolysis of chemical bonds and radioactive self-heating, its chemistry has mostly been investigated on the trace scale only. Meer weergeven Polonium is a chemical element with the symbol Po and atomic number 84. A rare and highly radioactive metal with no stable isotopes, polonium is a chalcogen and is chemically similar to selenium and tellurium, though its … Meer weergeven Tentatively called "radium F", polonium was discovered by Marie and Pierre Curie in July 1898, and was named after Marie Curie's native land of Poland (Latin: Polonia). … Meer weergeven Polonium-based sources of alpha particles were produced in the former Soviet Union. Such sources were applied for measuring the thickness of industrial coatings via attenuation … Meer weergeven • Polonium halo • Poisoning of Alexander Litvinenko Meer weergeven Po is an alpha emitter that has a half-life of 138.4 days; it decays directly to its stable daughter isotope, Pb. A milligram (5 curies) of Po emits about as many alpha particles per second as 5 grams of Ra, which means it is 5,000 times more radioactive than radium. … Meer weergeven Polonium is a very rare element in nature because of the short half-lives of all its isotopes. Seven isotopes occur in traces as decay products: Po, Po, and Po occur in the Meer weergeven Overview Polonium can be hazardous and has no biological role.
