Heavy noble gas
Rn is the chemical symbol for radon, a radioactive noble gas that occurs naturally from the decay of uranium in soil and rock.
Radon is colorless and odorless, making it undetectable without testing.
It can accumulate in buildings, particularly basements, and prolonged exposure increases lung cancer risk: The home inspector tested for Rn levels.
