State Rep. Jon Cross Introduces the Program
Our team at Air Duct Cleaning & Radon Co. is officially certified by the State of Ohio for radon testing, a requirement that's becoming increasingly important in the mortgage process. Real estate professionals recommend radon testing and mitigation to both sellers and buyers due to the significant health risks associated with radon exposure, including a higher risk of lung cancer, particularly in children.
The testing procedure we follow is straightforward. A monitoring device is positioned in the basement or close to the mechanical area in slab homes. For accurate results, it's critical that this device remains undisturbed for a period of 48 hours. Following this period, the data is analyzed to determine the radon levels. If radon concentrations exceed 4.0 picocuries, which is currently the threshold for mitigation, necessary steps are taken to address it.
After the 48-hour testing period, we retrieve the device, though its readings can also be accessed online. The results of the test are then promptly shared with the homeowner, providing clear insights into the radon levels in the property.
Once the testing has been returned and shows that the radon level is high enough (Over 4 picocuries), there are two types of possible mitigation – Passive and Active.
Passive Mitigation
In an existing home, a pipe inserted into the slab or through the basement floor – unless a sump pump has been installed, in which case the pipe can be inserted into the sump which and will then be fitted with a sealed cover. The pipe is then run either straight out a wall into the outdoors where it is then fitted with an upright connected pipe to vent into the atmosphere.
Passive systems depend on the “stack effect,” air pressure differentials create buoyancy to move air and radon gas through the pipe from the basement to the exhaust vent. This is occurs because there is difference between indoor and outdoor air density resulting from temperature and moisture variations.
Proper installations involve retesting or a monitoring system – which will show whether the passive system is reducing the radon level below the danger level. If it isn’t, the system can be converted an active mitigation by adding an exhaust fan
The process is the same as with passive mitigation but includes an exhaust fan to increase the flow of radon and air. An electrical outlet is required to power the radon fan.
Typically, if the initial radon level is significantly high, the recommendation for mitigation will be that an active system be installed. This will resolve the issue and is less costly because there will be only the single installation instead of having to add the fan later.
Mitigating Radon in New builds
This requires:
Some people think that Radon testing and mitigation is a scam, just a way to scare people into paying for work that they really don’t need. That’s absolutely not true. Radon is real, it’s actually on the Periodic Table of Elements (Number 86,) in the atomics section, it is the heaviest known gas and it can be deadly.
Radon zones have been determined and Ohio has one of the most seriously affected states. Central Ohio in particular is in the “high danger” zone. There is virtually no doubt that any structure tested within that area will require mitigation.
Radon is a radioactive gas that seeps into homes through basements or slabs and which has some very serious health consequences. Breathing in radon increases your risk of lung cancer. It is the second leading cause of lung cancer in the United States. (Smoking is number one, and second-hand smoke is number 3.)
Once it was proven to be a deadly substance, it took time for the real estate market to actually accept its danger. Now, however, more and more lenders for residential properties are requiring testing – and mitigation – because of the liability they could face by not requiring the testing.
