Radon – Part 2

Understanding Radon in Your Home: Testing, Levels, and Remediation

By Anne-Marie Greenberg, Realtor

Radon is a colorless, odorless, and tasteless radioactive gas that can seep into your home from the ground. It’s a health concern that every homeowner should be aware of. In this blog post, we’ll explore what radon is, how to test for it, the levels requiring remediation, and the different types of tests available.

When purchasing a home I will advise my Buyer clients on the importance of Radon detection, the methods and the remediation options that are best.

What is Radon?

Radon is a naturally occurring gas that results from the decay of uranium in soil and rocks. When radon is released from the ground, it can enter your home through cracks in the foundation, gaps around utility penetrations, and other openings. Radon is considered a serious health risk, as it can lead to lung cancer when its radioactive particles are inhaled.

Testing for Radon:

Testing your home for radon is a straightforward process and an essential step in maintaining a healthy living environment. There are two main types of radon tests:

1. Short-Term Tests: These tests typically last from two to seven days. They provide a quick snapshot of radon levels in your home and are useful for initial assessments or real estate transactions. Tests can be purchased at any hardware store or online. Make sure to follow all instructions prior to setting up a self-test (including keeping all windows and doors closed in the area being tested)

2. Long-Term Tests: These tests can run for more than 90 days, providing a more accurate picture of the average radon levels over time. Long-term testing is recommended for a more comprehensive understanding of your home’s radon exposure. A radon specialists should be contacted to set up and monitor the test.

You can either purchase a DIY radon test kit or hire a professional to conduct the test. Ensure that the kit or service you choose is certified and follows recognized testing protocols.

Levels Needing Remediation:

The Environmental Protection Agency (EPA) has set a recommended action level of 4 picocuries per liter (pCi/L) for radon in homes. If your short-term test results reveal levels at or above this threshold, it’s essential to take action. Long-term tests can provide a more accurate picture of your home’s radon levels and whether remediation is required.

Remediation for Radon:

Remediation, or radon mitigation, is the process of reducing elevated radon levels in your home to an acceptable range. There are several methods used for radon remediation:

1. Sub-Slab Depressurization: This is the most common and effective method. It involves creating a suction point below the concrete slab of your home, which removes radon gas and vents it safely above the roofline. This work should be done by a radon mediation specialist. There are interior systems and exterior systems. Make sure to understand the differences and select what is best for your home accordingly.

2. Ventilation:  Improved home ventilation can help dilute radon levels, especially when the house is tightly sealed.

3. Crawl Space Encapsulation: If your home has a crawl space, encapsulation can prevent radon from entering your living space by sealing it off and adding a vapor barrier.

4. Sump Pump Covers: If your home has a sump pump, sealing the sump pit and adding a vent pipe can prevent radon entry.

It’s important to hire a qualified radon mitigation professional to assess your specific situation and determine the most appropriate remediation method for your home.

Conclusion:
Radon is a potential health risk that every homeowner should take seriously. Testing for radon is a simple and necessary step to ensure the safety of your living environment. If elevated radon levels are detected, remediation methods can effectively reduce your exposure and protect your family from the associated health risks. Don’t wait; test your home for radon and take action if necessary to secure a healthier and safer living space.
