Isotopen van radon
Es Chemisches ElementRadon (Rn), mit a Atommasse ab ca. 222 Sie, besitzt keine stabile Isotope und wird somit klassifiziert als radioaktivElement. die 35 Radioisotope sind instabil und haben eine relativ kurze Halbwertszeit (meistens weniger als eins). zweite). Spuren der Radioisotope finden sich in der Natur 218rn, 219rn, 220rn (ebenfalls thoron erwähnt) und 222rn vor dem.
Das kurzlebige Isotop von Radon ist 196Rn, mit einer Halbwertszeit von etwa 4,7 Millisekunden. Die langlebigste ist 222Rn, mit einer Halbwertszeit von 3.823 Tage.
