Measuring radon levels in the home is vital. It is an odorless, colorless radioactive gas that is harmful in high doses over a long period of time. The EPA, WHO, and the American Cancer Society recommend testing it and of course, we do too. But what next? The key is to measure daily, as radon levels fluctuate constantly.
Airthings has compiled our top five easy tips for reducing the radon levels indoors. Long-term radon detectors are great as you can continue to monitor the levels and check that levels are reduced sufficiently.
Five easy DIY radon tips:
Experiment with ventilation by opening windows and vents to ensure air is flowing throughout the house.
Sealing access points
Draft excluders and rubber seals are an inexpensive way to seal around doors and other access points in a building. This can be beneficial if the aim is to reduce radon levels in basements. Click here for sealant recommendations.
Using caulking products will enable you to seal entry points in floors and walls of the home. Click here for further explanation of caulk products.
Clear natural underfloor ventilation
Homes with a suspended ground floor and space underneath often have underfloor vents. Oftentimes these can become blocked with foliage or dirt, clear the obstruction to improve the ventilation. Please note, some are intentionally blocked to prevent drafts, so speak to a professional if you are unsure.
Radon often enters buildings through the ground. Sealing large cracks and openings in any home is good for energy consumption and can also help with radon. As a gas, it can still get through smaller cracks, but as with anything, large entry points are unhelpful. There are numerous professionals that can help with this process too.
You’ll notice a key theme here; ventilate, ventilate, ventilate! As radon is an odorless, colorless gas in the air all around us, it’s impossible to avoid. Our 5 tips are to help get you started—it is important to continue measuring to be sure these actions are making an impact.
Radon is dangerous and should be taken seriously. These tips can help lower radon levels but should not replace professional help. If your radon levels are in the high range for more than a month, contact a professional. The EPA offers suggestions on choosing a radon mitigator and WHO provides information on radon action levels. Through sufficient ventilation or radon mitigation, you can help to ensure that dangerous levels do not collect inside.
