Radon [is a] highly radioactive inert gas occurring in nature as radon-222, a decay daughter in the radioactive disintegration of uranium 238. It is an alpha particle emitter, having a half-life of 3.8 days and is a considerable hazard to those engaged in uranium mining, as its decay daughters are, too, radioactive. 7, record 1, English, - radon

Le radon [...] fut découvert en 1900 par Dorn qui l'appela «émanation du radium». En 1908-1910, Ramsay et Whytlaw-Gray isolèrent cet élément et découvrirent qu'il constituait le plus lourd des gaz connus. Il est inerte chimiquement et occupe la dernière place du groupe O de la classification périodique. 3, record 1, French, - radon
