Radon, an insidious Class A carcinogen gets into homes, schools and buildings which can become trapped resulting in radioactive exposure many are unaware of. If radon levels are elevated, the occupants are at risk of increased exposure.
The way to fix a building with elevated radon levels is by installing a sub-slab depressurization radon mitigation system to remove the radon. How do you know the levels are safe once the system is installed? Re-test the property 24-48 hours after the system is active and running.
Unfortunately, may homeowners never re-test post mitigation. The only way to know if a system is working properly is to re-test the property after initial installation and every 2+/- years following installation. If levels are still elevated post mitigation, additional suction points may need to be added or possibly a larger fan. You won’t know unless you re-test! Some homes may require more than one system and this can be dependent on if there is one foundation slab, split foundations, large extensions or size of the home.
For a safe internal home or building environment, testing for radon every 2+/- years and re-testing when appropriate is imperative to keep radon concentrations below EPA action level of 4.0pCi/L and preferably, below the EPA’s concern range of 2.0-4.0pCi/L.
Testing for radioactive radon gas is not an expensive process and will depend on the the type of test that is performed. If you have a low budget yet want to make sure your family is safe, there are many states that offer free test kits from the Department of Public Health.
Continuous Radon Monitors also known as CRM, is an active method of testing and on average, costs approximately $175-$225 per test depending on where in the country you live. These costs are for the Northeast of the United States. CRM’s are analyzed by the provider and results are provided within hours of completion.
Passive testing using canisters, vials or pouches can run approximately $70-$110 and are analyzed by a lab due to the contents of the medium. The results are provided after the lab has completed their analyses which can take several days.
The small fee it costs to test for radon is in return huge for of peace of mind and the health of your family. If your home tests elevated for radon gas, fix your home and save a life.
Are you a seller planning to market your home for sale with hopes for top dollar and a smooth transaction? Have you done everything to make your home appear in it’s best light? Paint, some light renovation or maybe major renovation, spruced up the landscaping, even purchased all new appliances and are ready to hit the market. What’s missing?
A buyer coming into a home has questions and many of these questions can be answered by having a seller’s pre-sale home inspection. This includes testing for radon either by the home inspector, a certified radon tester or do it yourself with an EPA approved radon testing device.
If radon levels are elevated, either a radon mitigation system can be installed, re-tested with results provided to any potential buyer or the results can be shared with the buyer to make their own decision going forward. As a seller, you are being proactive to share the health of the house, not just the physical condition.
