True or False: Radon levels are uniform in every house.

Radon levels are not uniform in every house due to a variety of factors that influence radon concentration in different environments. Each building has different construction materials, foundations, soil types underneath, and ventilation systems, all of which can significantly affect the levels of radon present. For example, homes built on porous soils or those with cracks in the foundation may allow more radon to seep into the living spaces compared to homes with solid foundations and effective seals.

Additionally, geographic location plays a crucial role, as certain regions have higher natural uranium deposits, leading to increased radon levels. Variations in weather conditions and the use of heating and cooling systems can also affect how radon accumulates in a home over time. Therefore, it is accurate to state that radon levels can vary widely from one house to another, making the assertion that they are uniform in every home incorrect.
