radon
UK: ˈreɪdɒn | US: ˈreɪdɑːn
n. a radioactive, colorless, odorless, tasteless noble gas, chemical element (symbol Rn, atomic number 86).
The word "radon" combines "rad-" from "radiation" (referring to its radioactive properties) and the suffix "-on" (used for noble gases, e.g., neon, argon). It was named in 1900 by German chemist Friedrich Ernst Dorn, who discovered it as a decay product of radium. The suffix "-on" reflects its classification among inert gases, while "rad-" highlights its origin in radioactive decay.
Radon is a naturally occurring gas that can accumulate in poorly ventilated buildings.
Prolonged exposure to radon increases the risk of lung cancer.
Scientists measure radon levels to assess environmental radiation hazards.
The basement had high concentrations of radon, requiring mitigation.
Radon detectors are essential tools for home safety inspections.
