EMANON

Archaic term once used to denote all radon isotopes collectively, when the term radon was restricted to the isotope radon-222, the naturally occurring intermediate of the uranium-238 radioactive series; so called because original names for radon-219, radon-220, and radon-222 were, respectively, "actinium emanation," "thorium emanation," and "radium emanation." Origin: L. Emano, to flow out + -on
