Polonium-210 can either be extracted from rocks containing radioactive uranium or separated chemically from the substance radium-226. Production of polonium from radium-226 would need sophisticated lab facilities because the latter substance produces dangerous levels of penetrating radiation.

notorious assassinations when ex-KGB spy Alexander Litvinenko is attacked with the nuclear poison — Polonium 210, in London's 5-Star Millennium Hotel. där m är massan av polonium-210 i μg och t är tiden i dygn räknat från mätningens början.

For someone to be poisoned with 210Po, a large radiation dose would be needed. John Harrison and colleagues estimated Litvinenko ingested about 4 GBq of 210Po, which delivered a dose in the range of 20 gray, Gy, to 100 Gy (Harrison Polonium 210 i naturen. Den radioaktiva isotopen Polonium 210, (Po-210), finns i små mängder i naturen. Förekomsten härrör från sönderfallskedjan som börjar med uran 238. Polonium 210 sönderfaller under utsändande av alfastrålar till stabilt bly. Halveringstiden är 138 dagar.
Polonium-210 has a half-life of 138.39 days. Polonium's most stable isotope, polonium-209, has a half-life of 102 years.
Po-210 is one of 25 radioactive isotopes of polonium – it decays to lead by alpha particle emission, with a half life of 138 days. So the polonium used to kill Litvinenko must have been made
(Po-210) isotope, presumably via ingestion, sparked renewed interest in Polonium-210, the predominant isotope of polonium, is radioactive and emits alpha particles on decay.

Polonium-210 in tobacco contributes to many of the cases of lung cancer worldwide. 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. Polonium 210 i naturen Polonium 210, 210Po (Po-210), finns i små mängder i naturen. Ytterst härrör ämnet från sönderfallskedjan som börjar med uran 238. Uran 238 sönderfaller via fem steg till radium 226 och radon 222 och dessa omvandlas i sin tur i en flerstegsprocess till polonium 210 och Polonium används i borstar för borttagande av damm på fotografisk film. Stor försiktighet måste då iakttas.
Po-210 results from the natural radioactive decay of uranium, which is commonly found in Sierra Nevada granites. Po-210 emits alpha particles, which makes it decay to form a stable isotope of lead. Discovered by Marie Curie in 1898, Polonium-210 is one of 20 known radioactive isotopes of the element, according to Chemistry World. Toxicologists say a single gram of the substance could kill as

As polonium-210 emits very energetic alpha radiation, it has a high radiotoxicity; its chemical toxicity is orders of magnitude lower and is therefore not relevant for health assessment. Polonium-210 là một đồng vị của nguyên tố Polonium, được khám phá đầu tiên bởi khoa học gia Marie Curie vào cuối thế kỷ 19. Polonium-210 là một chất cực độc, chỉ cần một lượng rất nhỏ cũng đủ để gây chết người. Polonium-210 gây chết người bởi nó phóng ra hạt anpha với năng lượng đủ để làm hỏng cỗ máy gen tế bào.

Polonium-210 is a radioactive isotope that occurs in small amounts in nature and can be made in a nuclear reactor. It has limited uses, mainly in static eliminators. In recent years, polonium made the news because of its use as a poison. Polonium was blamed for the Nov. 23, 2006, death in London of the Russian Alexander Litvinenko.
En av dem Atommassa: 209,982848, u, polonium 210.

Poloniumin yleisin isotooppi, polonium-210, on uraani-238:sta alkavan hajoamissarjan viimeinen radioaktiivinen jäsen. Sen puoliintumisaika on 138 päivää, ja se muuttuu hajotessaan (alfahajoaminen) pysyväksi Pb-206-lyijyisotoopiksi. Curiet mittasivat poloniumin olevan 400 kertaa radioaktiivisempaa kuin uraani.
Use of 210 … 210 is considered to be one of the most hazardous radioactive materials known, but it must be breathed in or eaten to exert its toxic effects. Your skin or a piece of paper is enough to stop the radiation emitted by Po-210. What are common uses of Polonium 210?
