Radon gas, which despite its molecular weight can be pushed upward from underground, and remain in walled or windowless basements.

Radon is a radioactive element that is considered an indoor pollutant. It is a colorless, odorless gas that can seep into buildings through the ground and accumulate to dangerous levels, especially in poorly ventilated spaces. Long-term exposure to radon can increase the risk of lung cancer.
Radon is a radioactive gas that is formed from the natural decay of uranium in soil, rock, and water. It is colorless, odorless, and tasteless, making it hard to detect without testing. Radon is the leading cause of lung cancer in non-smokers and can be a serious health risk when present in indoor spaces.
Asbestos and radon contribute to indoor air pollution. Asbestos fibers can be released into the air from building materials, while radon is a naturally occurring radioactive gas that can seep into homes from the ground. Both substances pose significant health risks when inhaled.
In itself it is not a disease. Indoor air pollution is 3x to 5x higher indoors than outdoors. Indoor air pollution is caused from conventional household cleaners, aerosol sprays, and fragrances.
Indoor air pollution can be worse than outdoor air pollution because indoor spaces can trap pollutants and chemicals, leading to higher concentrations of harmful substances. Factors such as poor ventilation, smoking, and household products can contribute to poor indoor air quality.

No, radon is not a thick brownish haze; it is a colorless, odorless, radioactive gas that is produced naturally from the decay of uranium in soil, rock, and water. It is typically found in indoor environments, particularly in basements and poorly ventilated areas. The brownish haze you might be thinking of is likely smog or particulate matter resulting from air pollution and chemical reactions in the atmosphere.
The indoor air pollutant you are referring to is carbon monoxide (CO). It is a colorless, odorless gas that can be produced by the incomplete combustion of fuels such as wood, coal, oil, or gas. Exposure to carbon monoxide can be dangerous, as it can lead to serious health issues, including poisoning, if inhaled in significant amounts. Proper ventilation and the use of carbon monoxide detectors are important for reducing the risk of exposure.
