Изотопи на радонот

Познати се 39 изотопи на радон (<sub>86</sub>Rn), од <sup>193</sup>Rn до <sup>231</sup>Rn, сите се радиоактивни. Најстабилен изотоп е <sup>222</sup>Rn со време на полураспад од 3,8235 дена, кој се распаѓа на полониум-218. Шест изотопи на радонот, <sup>217, 218, 219, 220, 221, 222</sup>Rn, се појавуваат во трагови во природата како распадни производи од, соодветно, <sup>217</sup>At, <sup>218</sup>At, <sup>223</sup>Ra, <sup>224</sup>Ra, <sup>225</sup>Ra и <sup>226</sup>Ra. <sup>217</sup>Rn и <sup>221</sup>Rn се произведуваат во ретки гранки во распадната низа на траги од <sup>237</sup>Np, <sup>222</sup>Rn (и исто така <sup>218</sup>Rn во ретка гранка) е меѓучекор во распадната низа на 238</sup>U,<sup>219</sup>Rn е меѓучекор во распадната низа на <sup>235</sup>U, и <sup>220</sup>Rn се јавува во распадната низа на <sup>232</sup>Th.
