What is radon primarily known for?

Radon is primarily recognized as a colorless and odorless gas that can pose significant health risks, particularly as a leading cause of lung cancer among nonsmokers. It is produced naturally from the decay of uranium found in soil and rocks. Because it is undetectable by human senses, many people may unknowingly be exposed to high levels of radon in their homes.

Radon's reputation for being hazardous is largely due to its gas form allowing it to seep into buildings, where it can accumulate to dangerous levels, especially in lower areas like basements. Testing for radon levels is crucial for homeowners, particularly in regions where radon is prevalent. This focus on health risks and the properties of radon differentiates it from pollutants or construction materials, hence its association with serious health concerns rather than other applications.
