Radon is a radioactive gas that is formed by the natural decay of uranium and thorium in the soil and rock beneath our homes. Radon can seep into our homes through cracks and gaps in the foundation or walls, and it can accumulate in the air we breathe. Exposure to high levels of radon gas can be a significant health risk, as it is the second leading cause of lung cancer after smoking. In this article, we will discuss the radon entry and vacuum effect in homes with radon and how it can impact radon levels.
What is the Vacuum Effect?
The vacuum effect occurs when there is a difference in air pressure between the inside and outside of a home. This pressure difference can cause air to move from one area of the home to another, and it can also cause radon gas to be pulled into the home from the soil and rock beneath it. The vacuum effect can be caused by a variety of factors, including:
Strong winds can create areas of low pressure on the leeward side of a home, which can cause air to be drawn into the home.
The stack effect is caused by the difference in temperature and pressure between the inside and outside of a home. This difference can cause air to be drawn into the home through lower-level openings, such as cracks in the foundation or walls.
Heating, ventilation, and air conditioning (HVAC) systems can create a vacuum effect by drawing air out of the home and creating areas of low pressure.
How Does the Vacuum Effect Impact Radon Levels?
The vacuum effect can impact radon levels in a home by drawing radon gas from the soil and rock beneath the home into the living space. This can occur through cracks and gaps in the foundation or walls, or through other openings in the home’s exterior.
The vacuum effect can also cause radon levels to be higher in certain areas of the home, such as the basement or crawl space. These areas are typically at a lower level than the rest of the home and are more likely to be affected by the vacuum effect.
How Can the Radon Vacuum Effect Be Mitigated?
The vacuum effect can be mitigated through a variety of methods, including:
Sealing Cracks and Gaps:
Sealing cracks and gaps in the foundation or walls can help to prevent the vacuum effect from drawing radon gas into the home.
Installing a Radon Mitigation System:
A radon mitigation system can be installed to reduce the levels of radon gas in the home. These systems typically include a fan and a vent pipe that is installed beneath the home’s foundation. The fan pulls the radon gas from beneath the home and expels it outside, where it is dispersed harmlessly into the air.
Improving ventilation in the home can help to reduce the vacuum effect by equalizing the air pressure inside and outside of the home. You can accomplish this through the use of exhaust fans, opening windows and doors, or installing a mechanical ventilation system.
Test Your Home for Radon Entry
The radon entry and vacuum effect can impact your radon levels. Keep your family safe, test your home for radon. You can order a Test Kit online or contact Radon Be Gone for professional Radon Mitigation services.
