Understanding How Radon Enters Your Home

Radon gas is present in soil and rock, and can seep into homes through cracks and openings in your foundation. Radon is a concern for homeowners because prolonged exposure to high levels of radon can cause lung cancer. In fact, it is the second leading cause of lung cancer in the US. 

When the soil is disturbed, for example, during construction, the radon gas can be released into the air. Radon then enters your home through cracks and openings in the foundation. Radon can also enter your home through well water.

Even with the most solid foundation, small cracks and openings can occur over time. Radon can also enter your home through sump pumps, crawl spaces, and floor drains.

Radon enters your home through a process known as air pressure differentials. Your home has a lower air pressure than the soil surrounding it. This creates a natural pressure gradient that allows radon to enter your home through cracks, openings, and other areas of the foundation.

Heating and air conditioning systems can also be a source of radon. It can enter your home through the outdoor air intake, and then circulate throughout your home. In addition, a poorly ventilated furnace or a blocked chimney can contribute to higher levels of radon.

Testing is the first step in preventing exposure to high levels of radon. If high levels are detected, Standard Water is here to help with a top quality radon mitigation system. Contact us today!
