Radon Test Results 2013

Homebuyers in Naples, Marco Island, Bonita Springs, Estero and Ft Myers are always asking has there been any tests in a certain complex or on a certain street.
We will be posting the radon test results for most of the (our) tests in Bonita Springs, Naples, Estero, Ft Myers etc.  Since there will be thousands of test results posted, please be patient.

Elevated radon levels are common in Bonita Springs, Naples, Bonita Springs, Estero and Ft Myers Condos and often found in single family homes.  If the home you plan to buy has an elevated radon level, you should request the seller have a FL DOH certified radon mitigation business  lower the levels below 4.0 pCi/l.

Bonita Springs homebuyers should understand that radon is a cancer causing radioactive gas.  Naples homebuyers should hire a FL DOH certified measurement person that uses a continuous radon monitor rather than just a passive test.  The charge for each is about the same but with a monitor, you receive an hour by hour printout of the radon levels and have less chance that the test is compromised  without you knowing it.

Radon Test results listed for zip codes and/or street and city in Collier and Lee Counties including cities of Naples, Bonita Springs, Estero, Ft Myers, Marco Island, and some in Cape Coral.

After performing thousands of radon tests in Naples, Bonita Springs, Estero and Ft Myers, we believe about one out of four condo's have elevated radon.  REALLY common on 1st floor units.  Consumers should remember elevated radon levels should be treated as just another home repair.

 First Naples condo radon test levels went from 0.0 pCi/l to 8.1pCi/l  and back to zero and back up. Did someone leave a door or window open and compromise the first test?


It is important that everyone involved with a radon test understand that the home must be in “closed house conditions” 12 hours before and during the short term radon test (minimum of 48 hours).

First radon test performed by XXX radon measurement business in Naples Condo was unusual, second test performed by us was typical or normal. 

Good morning
I am able to speak of radon and its occurrence generally, but any specific home or building will have unique characteristics that can only be determined by testing over different times to account for variations in building pressures, ventilation rates, occupant behavior and the weather. I can assess the test performed by Doug Wall and have the ability to talk specifics there, but you would need to contact (other measurement business) about the first test as I have no knowledge other than your brief description here.

Indoor radon concentrations are a combination of the source strength, preferred pathways, ventilation rates, and air pressures. In most of the US, buildings have a negative pressure in the lower portions which draws soil gas into the structure. This situation often creates fluctuations, sometimes significantly, during a 24 hour period where the radon is at its highest in the wee hours of the morning, falling through the afternoon and then begins rising again as the sun angle declines. This diurnal pattern will also have season trends as the main driving force is the outdoor temperature because the house is essentially acting like a chimney. Rain and wind can compound the pressures or in some cases, cause the radon to rise or suddenly drop for several hours at a time.

In Florida and other Southeastern cities, we see radon emanating out of the concrete-based structures, which can indeed build up to beyond EPA's radon Action Level (4 pCi/L). These situations are typically influenced less by the weather as the main mechanism is the ventilation rate, often measured in terms of air exchanges per hour. What I normally see in a concrete condominium is a steady radon concentration that does not show the cycling that I described above, as the fluctuations are typically caused by the occupants entering or leaving the unit, which is OK as long as the doors are closed behind them. If a concrete condo is ventilated to air the place out, the radon will fall to nearly nothing and when closed up again there is a very slow, steady rise in the radon that can often take 2-3 days to finally plateau. When the units are not ventilated and closed, I expect to see a very steady radon concentration during the test.

When I look at the test that Doug Wall performed for you, I see a very steady radon concentration and a very steady indoor temperature. This does not seem to indicate tampering with the environment and may be a valid test. I cannot know for sure however, since I am in Western NC and cannot know more than what the machine and the measurement technician tells me. At this point, everything looks fine on test #2.

Now the tricky part. The radon program in Florida is administered by the Department of Health. They make the rules that Mr Wall and I are required to follow. It is the policy of the FL DOH that during a real estate transaction, the first radon test is the one used to determine the need for mitigation, not the second (or third) one. The reason is so someone with a vested interest in the results may be tempted to alter the environment on there is knowledge of elevated radon during the first test.  The DOH position is based upon the US EPA's Home Buyer's and Seller's Guide to Radon, which also says to test once and if all of the protocols were followed, fix then the readings are 4 pCi/L or higher. I offer this as a historical perspective, not in an accusational way because I have no idea which party you are in this transaction.

Elaborating on this thought just a bit further, there are cases where the initial test is indeed invalid and should be thrown completely out. Examples of this include, but are not necessarily limited to: machine malfunction, protocol violations (either due to the professional's placement error or occupants violating closed-building protocols), devices being out of calibration range, and extreme or unusually severe weather. The weather statement is tricky however, and what is normal is Wyoming, isn't normal in New York nor in South Florida. An afternoon thunderstorm can happen in any of the three location examples of course, but a 2 inch rain in Wyoming might be deemed far more extreme than any of the states along the Gulf of Mexico. Tropical storm remnants that produce 8 inches of rain and 40 mph winds isn't that normal though and could probably be a cause to throw a test out. The harder part is exactly knowing where the lines fall. I have clients that are asked to invalidate tests because it sprinkled, but that is definitely not severe or extreme, even in Phoenix. So the larger question in my mind is whether the first test shows machine malfunction, protocol problems, or extreme weather? I don't know the answer, but these are the questions that arise in my mind.

I may suggest that you look at the weather history for your area which is available at The Weather Underground website to see if there was something truly extreme going on during the first test. A call to (other measurement business) may also be helpful to understand whether the pattern they see on the first test is a typical test from South Florida.
