Изотопи на радонот

Познати се 39 изотопи на радон (86Rn), од 193Rn до 231Rn, сите се радиоактивни. Најстабилен изотоп е 222Rn со време на полураспад од 3,8235 дена, кој се распаѓа на полониум-218. Шест изотопи на радонот, 217, 218, 219, 220, 221, 222Rn, се појавуваат во трагови во природата како распадни производи од, соодветно, 217At, 218At, 223Ra, 224Ra, 225Ra и 226Ra. 217Rn и 221Rn се произведуваат во ретки гранки во распадната низа на траги од 237Np, 222Rn (и исто така 218Rn во ретка гранка) е меѓучекор во распадната низа на 238U, 219Rn е меѓучекор во распадната низа на <sup>235</sup>U, и 220Rn се јавува во распадната низа на Th.
