To measure the level of radon gas for safety reasons

The primary purpose of a radon test in a home is to measure the level of radon gas for safety reasons. Radon is a naturally occurring radioactive gas that can seep into homes from the ground and is known to pose significant health risks, particularly the risk of lung cancer with prolonged exposure. Therefore, understanding the concentration of radon in a living space is crucial for occupants' safety.

Conducting a radon test helps identify whether the radon levels exceed the recommended safety threshold established by health authorities. If elevated levels are detected, homeowners can take necessary actions, such as installing radon mitigation systems, to reduce exposure and improve indoor air quality. This testing is especially important in areas known to have high radon levels and is an integral part of ensuring a safe living environment.
