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. The important one is polonium-210, which happens to be the one discovered by Curie. Uranium atoms slowly decay into other atoms, eventually ending up as lead but with polonium as one stop on the way. Name Origin From Poland, country of Pierre and Marie Curie.

Polonium 210 uses

It is used to insulate instruments in Russian lunar landing craft, remove static electricity, inspect oil wells, and measure the thickness of industrial coatings. It was used in early nuclear weapons, but its short half-life meant the polonium products didn’t have much shelf life. It was used as part of the detonator in the atomic bomb that was dropped on the Japanese city of Nagasaki during World War II. While plans were drawn up to use polonium 210 as a power source, and one federal document said it was used, nuclear experts say that the government decided instead to rely on plutonium 238; no American satellites ever flew with polonium 210.” Polonium-beryllium alloys are used as trigger or neutron in initiators of nuclear weapons. Polonium is used for discovering oil wells.

Polonium 210 uses

Extraction Polonium occurs so rarely and has so few uses that it is extracted from natural ores only for the purpose of research. Uses Polonium releases a great deal of energy during its radioactive breakdown. This has led to Polonium is a very rare natural element. It is found in uranium ores but it is uneconomical to extract it. It is obtained by bombarding bismuth-209 with neutrons to give bismuth-210, which then decays to form polonium.

Polonium-210 is a very strong emitter of alpha particles.
