The result is that the nucleus changes into the nucleus of one or more other elements. These daughter nuclei have a lower mass and are more stable (lower in energy) than the parent nucleus. Nuclear decay is also called radioactive decay, and it occurs in a series of sequential webpage-http://www.kentchemistry.com/links/Nuclear/naturalTrans.htmThis short video walks you through how to write an alpha decay expression.

During a project work at Norra Reals gymnasum I analyzed the radon nuclides populated in the decay chains of radon using high-resolution gamma-ray spectroscopy, both with respect to 222Rn and the short-lived radon isotope 220Rn. av JC Lorentzen · 2020 · Citerat av 3 — These constructions were prone to dampness and attack from wood decay fungi, from 1998 on “220 schools, damage and defects in school buildings” (tr) [57].

the above is the sequential decay series. when radon-220 undergo alpha decay, polonium-216 is produced, polonium after alpha decay lead is produced and lead after beta decay bismuth is produced and bismuth produces thallium after alpha decay.

220 Rn has a half-life of 56 s and therefore has a much greater chance to decay before becoming airborne. The actinium series produces 219 Rn, also called actinon , after several transformations from the relatively rare original 235 U nuclide.
