Radon is a colorless, odorless, tasteless radioactive gas that can seep into homes and pose a serious health risk. According to the Environmental Protection Agency (EPA), radon is the second leading cause of lung cancer in the United States, responsible for an estimated 21,000 deaths each year. Fortunately, there are steps that can be taken to reduce radon levels in a home and protect yourself and your family from this invisible danger.

氡含量檢測

The first step in reducing radon levels in your home is to test for the presence of radon. Radon testing kits are readily available at hardware stores or online, and can provide you with an accurate measurement of radon levels in your home. It is recommended to test for radon at least every two years, or if you have made any structural changes to your home that could impact radon levels.

密封裂縫和開口

Radon enters homes through cracks and openings in the foundation and walls. By sealing these entry points, you can prevent radon from seeping into your home. This can be done using caulking or sealant to fill in gaps around pipes, wires, and other openings. Additionally, sealing sump pumps and drains can help reduce radon levels.

Ventilate the Home

Proper ventilation is key in reducing radon levels in a home. Opening windows and doors regularly to allow for fresh air circulation can help dilute radon gas and prevent it from accumulating indoors. Installing a ventilation system, such as a radon mitigation system with a fan, can further help to reduce radon levels by drawing the gas out of the home and venting it outside.

Install a Radon Mitigation System

If radon levels in your home are above the recommended action level of 4 picocuries per liter (pCi/L), it is highly recommended to install a radon mitigation system. There are different types of radon mitigation systems available, but the most common method is called sub-slab depressurization. This system involves installing pipes and a fan beneath the foundation of the home to draw radon gas from the soil and vent it outside before it can enter the home.

Regular Maintenance and Monitoring

Once you have taken steps to reduce radon levels in your home, it is important to regularly monitor and maintain your radon mitigation system to ensure it is functioning properly. This may involve periodic testing for radon levels, checking for cracks and openings that need to be sealed, and replacing components of the mitigation system as needed.



採取這些措施降低家中氡濃度，可以保護您和您的家人免受這種危險氣體的健康風險。如果偵測到氡濃度過高，必須迅速果斷地採取行動，因為長期暴露於氡會造成嚴重後果。記住，在氡問題上，防患於未然總是勝過亡羊補牢。
