First identified in 1898, and also marking the discovery of the element polonium, 210 Po is generated in the decay chain of uranium-238 and radium-226 Polonium-210 is an alpha particle emitting radioactive element with a half-life of 138 days. It appears at the end of the decay-chain of Uranium-238 where the long lived Lead-210 (22.3 a) decays to Bismuth-210, and finally Polonium-210. 210Po is introduced into the biosphere through various routes of terrestrial and marine radioecological pathways. The level of 210Po activity in drinking water. Few studies have reported on polonium-210, a decay breakdown product of radon-222 and lead-210, in human lungs and there has been no study in patients with suspected lung cancer. The main aim of this Polonium in vivo study was to evaluate polonium-210 radioactivity in bronchopulmonary systems of smoker, ex-smoker and never smoker patients with suspected lung cancer

Miligram 210 Po vyzáří za sekundu stejné množství alfa částic jako 5 gramů 226 Ra. Několik curie (1 curie je 3,7×10 10 Bq) 210 Po vydává modré světlo, což je způsobeno excitací okolního vzduchu. 1 gram tohoto izotopu uvolňuje 140 W energie decay, and the times shown are half-lives. An asterisk indicates that the isotope is also a significant gamma emitter. Uranium-238 also decays by spontaneous fission.

Polonium -210 is the only component of cigarette smoke that has produced cancer by itself in laboratory animals by inhalation - tumors appeared already at a polonium level five times lower than those of a normal heavy smoker. Lung cancer rates among men kept climbing from a rarity in 1930 (4/100,000 per year) to the No. 1 cancer killer in 1980 (72/100,000) in spite of an almost 20 percent.

polonium-210 chemical isotope Britannic

Polonium-210 is widespread in the biosphere, including in human tissues, because of its position in the uranium-238 decay chain. Natural uranium-238 in the Earth's crust decays through a series of solid radioactive intermediates including radium-226 to the radioactive noble gas radon-222 , some of which, during its 3.8-day half-life, diffuses into the atmosphere Mass numbers of typical isotopes of Polonium are 208-210. Atomic Mass of Polonium. Atomic mass of Polonium is 209 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element Summary - Polonium vs Plutonium. Although the names polonium and plutonium sound similar, they are different chemical elements that exist in two different groups and periods. The key difference between polonium and plutonium is that polonium is a post-transition metal, whereas plutonium is an actinide. Reference: 1. Polonium 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 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 What does polonium mean? A radioactive metallic element, occurring naturally in small quantities as a product of radium disintegration and produc..
