What’s measured during radon testing?

When radon testing, it’s measured in Picocuries per Liter; pCi/L’s. A Picocuries is simply the measurement of the rate of decay of radon, and Picocuries per Liter is measuring that radioactivity every 27 seconds in a volume of one liter. Which is about 0.037 decays per second in every liter of air, by the way. So 1 pCi/L is equal to about 2.22 disintegrations per minute!

Where should my radon levels be after radon testing?

According to the EPA, the national average for outdoor Radon levels is 0.4 pCi/L & the average indoor radon level is 1.3 pCi/L. It’s difficult to lower your radon levels below 2 pCi/L, but that’s where you should be aiming.

What radon levels are problematic after radon testing?

The EPA set 4pCi/L as the action level for the United States in 1988 and has remained the standard. The EPA labels all levels of radon from 4 pCi/L & above as “Fix Your Home” when advising what to do. But homes with readings between 2pCi/L & 4pCi/L should also consider mitigation. As of 2009, the World Health Organization (WHO) set its threshold to mitigate at 2.7pCi/L.

What are the health risks from radon?

If there is one thing that we can all agree on, it’s the importance of protecting our health. And yet, the health risks from radon go overlooked in many homes across America- despite it being the second leading cause of lung cancer; after cigarettes! According to both the National Cancer Institute (NCI)¹ & the EPA², Radon causes lung cancer in smokers and non-smokers alike. Scientists estimate that 15,000 to 22,000 lung cancer deaths in the United States each year are related to radon.

It’s also important to note that smokers who are exposed to high levels of radon are more likely to get lung cancer compared to non-smokers. As with most environmental health issues, the primary concern with radon gas is chronic exposure or exposure over a long period of time. The best thing a homeowner can do is to have a professional radon tester check their home every five years, or every two years if you have a mitigation system installed.

When should I be testing my home's radon levels?

For starters, both the EPA and the PA DEP recommend that you perform radon testing every five years, or every two years if you have a mitigation system installed to ensure that the system is continuing to operate correctly.

They also highly recommend getting radon testing services after any major home renovation, especially if it involves structural changes or foundation repairs, or even things like finishing your basement, replacing your HVAC system, window or siding replacements, and more. All of these processes can change the way that air moves in and out of your home, and could increase radon gas coming in from the soil.

Make sure to hire a licensed radon tester when buying or selling a home

Since radon enters your home from the soil beneath it, a problem can arise no matter what style, age, location, or building materials of your home. The average radon levels in each state can be drastically different due to things like terrain, uranium content in the soil, and how porous surface rock formations are. So whether the home is newly built, or is just new to you, the EPA & DEP recommends that homes in Pennsylvania are tested for radon by a licensed radon tester before being bought or sold.

Pennsylvania law also requires that all radon testing be performed by a certified third-party tester, and if you’ve tested the home’s radon levels they be disclosed to the potential buyer.
