(documentation Radon EnglishLanguage "Colorless radioactive gaseous element, belongs to the noble gases. Of the twenty known isotopes, the most stable is Rn-222 with a half-life of 3.8 days. Formed by the radioactive decay of {Radium}-226. Radon itself decays into {polonium}. Used in radiotherapy. As a noble gas, it is effectively inert, though radon fluoride has been synthesized. First isolated in 1908 by Ramsey and Gray.") | Mid-level-ontology.kif 30446-30451 | |
