Testing quality and practices

 
 

Quality, accuracy, and precision are important in professional radon measurement. Ohio has codified the EPA protocols for short-term and long-term radon testing in the Ohio Revised Code and Ohio Administrative Code. All radon professionals must be licensed after required training and an accredited exam. Radon testers in Ohio must be trained, tested, and licensed, and must take continuing education classes, exam, and renew their license every two years.

Radon Done utilized Sun Nuclear 1028 continuous radon monitors. Radon Done provides Ohio-licensed, independent, professional radon tests. Radon monitors must be calibrated annually by a third-party lab to ensure accuracy and precision, as required by Ohio law.

We have registered each of our continuous radon monitors and serial numbers with ODH, including a QA plan for each machine, and a radiological safety plan for our workers. Each active monitoring device iscalibrated and certified once per year by the manufacturer, and cross-checked against a recently calibrated device (within 45 days) every six months. Every tenth test we perform must be a duplicate (two devices side-by-side), with results reported to ODH.

As licensed radon testers, we maintain detailed records for all radon tests, including the address, radon level measured in every test, and the required equipment calibration, cross-checking, and duplicates to ensure accuracy and precision. Every test result from a licensed radon tester is recorded by Ohio Department of Health (ODH).

What are radon levels in Franklin county, Ohio?

Central Ohio has high radon potential according to the EPA. Average radon levels recorded and submitted to the Ohio Department of Health range from 2 to 4 Pci/L (picoCuries per liter), shown in light blue in the graphic below, to ZIP Codes with averages over 10 Pci/L, shown in red in below.

Although there is no safe level of radon exposure, the EPA Action Level for indoor radon is 4.0 Pci/L. The first step to understanding the radon level inside your own home is to test–this is something you can include with your home inspections when buying a home, or anytime for your current home. Even if you already have a radon mitigation system, the EPA recommends that you test your home every two years–many changes to your home can change the amount of radon trapped inside the living area, including new windows, siding, or roof.

What is radon gas?


Radon is an odorless, colorless, tasteless, radioactive gas. Radon comes from the decay of radioactive uranium that can be found in small amounts in rocks and soil throughout nature. In areas with disturbed earth, and loose fill, like when a home is built, radon escapes from the soil.

Radon gas exposure is the number one cause of cancer for non-smokers, even greater than second-hand smoke. Most people are exposed to radon gas inside their own homes, and this is their greatest exposure to natural ionizing radiation.

Radon gas in Ohio

Central Ohio has relatively high natural concentrations of uranium from glacial deposits and shale, which during radioactive decay, produces radium and radon.

The EPA’s current radon action level is four picocuries of radon per liter of air (4 pCi/L). Most counties in central Ohio have high potential for radon, with predicted average indoor greater than the EPA action level. According to one study cited by Ohio Department of Natural Resources Department of Geological Survey, 38% of Ohio’s 88 counties had average indoor radon levels above 4.0 pCi/L, but Licking County’s average was above 8.0 pCi/L. Seven Ohio counties—Carroll, Fairfield, Franklin, Harrison, Knox, Pickaway, and Ross—had average indoor Radon concentrations between 6 and 8 pCi/L.
