Where are higher levels of radon typically found in a home?

Higher levels of radon are typically found at soil contact levels such as basements due to the gas's natural origin. Radon is a radioactive gas that is produced by the decay of uranium found in soil and rock. Since radon is generated underground, it can seep into homes through cracks in floors and walls, construction joints, and gaps around service pipes.

Basements, being closer to the ground and often having direct contact with the soil, are particularly susceptible to higher concentrations of radon. The building structure can trap radon gas, allowing it to accumulate to levels that pose health risks if not properly mitigated.

In contrast, areas like attics and main living areas are generally farther from the soil contact point, making them less likely to have elevated radon levels. While half-bathrooms could potentially have radon, they typically do not experience the same concentration as lower levels of the home that are directly in contact with the soil.
