radon gas
Invisible home pollutant
Radon gas is a radioactive element that occurs naturally as uranium decays in soil and rock.
Colorless and odorless, it can seep into buildings through foundations and accumulate to dangerous levels, making it a leading cause of lung cancer among nonsmokers.
Home testing kits detect its presence.
The phrase is slightly redundant—radon is always a gas at normal temperatures.
