Radon Inspection

A radon inspection assesses the levels of radon gas in a home, as radon is a naturally occurring, radioactive gas that can be harmful when present in high concentrations. Here’s what a radon inspection typically covers and the process:

1. Radon Testing Methods:

There are two standard methods for radon testing:

   a. Short-Term Testing: This involves placing small radon testing devices, such as charcoal canisters or alpha-track detectors, in the lowest livable area of the home for a specified period, usually 2 to 7 days. After testing, the devices are sent to a laboratory for analysis to determine radon levels.

   b. Long-Term Testing: Long-term testing uses specialized detectors, like electret ion chamber detectors or continuous radon monitors, that remain in the home for an extended period, typically 90 days to one year. These detectors provide a more accurate picture of radon levels over time.

2. Location of Testing:

Testing is typically conducted in the home’s lowest livable area, as radon accumulates in basements and crawl spaces. However, testing is also performed on higher floors if those areas are occupied.

3. Radon Levels:

Radon levels are measured in picocuries per liter (pCi/L). The U.S. Environmental Protection Agency (EPA) has set an action level of 4 pCi/L. If the radon test indicates levels at or above this threshold, mitigation measures are recommended to reduce radon levels.

Red Flags for Home Buyers Regarding Radon:

When considering a home purchase, there are several red flags to watch out for regarding radon:

1. No Previous Radon Testing: If there is no record of radon testing in the home, it’s a good idea to request a radon test as part of the home inspection process.

2. High Radon Levels: If a radon test reveals levels at or above 4 pCi/L, this is a red flag. It doesn’t necessarily mean you should avoid the purchase. Still, it does mean that radon mitigation should be considered, and the buyer should negotiate with the seller accordingly.

3. Improper Radon Mitigation: If the home already has a radon mitigation system in place, ensure it has been properly installed and is in good working condition. An improperly installed system may not effectively reduce radon levels.

4. Location and Geology: Homes in some geographic regions may be more prone to high radon levels due to local geology. Research the radon risk in the area where the home is located.

5. Disclosure: In some regions, sellers are legally required to disclose radon test results and any radon mitigation systems in place. Ensure you receive this information from the seller.

6. Consult Professionals: It’s advisable to consult with a qualified radon mitigation professional if you have concerns about radon in the home. They can assess the situation and recommend appropriate measures.

Radon testing is essential to home-buying, especially in areas with a known radon risk. Red flags include high radon levels, lack of testing, improper mitigation, and geological factors. Addressing radon issues can help ensure the safety and health of occupants in the home.
