You closed on a Naples home last month, and somewhere in the stack of paperwork was a line about radon that you signed without stopping. Now you are wondering whether it mattered. You cannot smell radon, you cannot see it, and the map you found online puts most of Florida in the low-risk color, which felt reassuring until you read that the map describes counties, not houses. The honest position is simple. A map cannot tell you what is in the air under your slab. Only a measurement can, and the company that would sell you the fix is not the company you want deciding whether you need one.

What radon is and what a Naples radon test measures
Radon is a naturally occurring radioactive gas. It forms as uranium in soil and rock breaks down, and it seeps up through the ground and into a building through cracks in the slab, gaps around plumbing, and the seams where the foundation meets the walls. Outdoors it disperses and is harmless. Indoors it can accumulate, and because it is colorless and odorless, the only way to know the level in a specific home is to measure it.
A radon test measures how much of the gas is present in the air you breathe, reported in picocuries per liter, written pCi/L. A licensed measurement technician places a device in the lowest lived-in level of the home, leaves it for a set period, and either reads it on site or sends it to a laboratory. What comes back is a number for your house, on your soil, under your slab, not an average for your zip code.
The number is the product. Everything AirMD is paid to do ends when that measurement is in your hands.
Why the map cannot answer for your house
The EPA radon zone map predicts risk by county, based on geology and past readings across a wide area. Two homes on the same street can test very differently depending on soil, construction, and how the house is sealed and ventilated. A low-risk county is a starting assumption. Your own device produces the result.
Measurement versus mitigation, and why they should be two companies
The short answer is this: measuring radon and fixing radon are two different jobs, and AirMD does only the first one. AirMD measures the level in your home. It does not install radon mitigation systems, and it does not remediate. That boundary is the whole point of hiring it.
Consider what a mitigation contractor is paid to do. It installs a system, usually a vent pipe and a fan that draws the gas from beneath the slab and releases it above the roof. That is real, useful work when a home needs it. But when the same contractor also runs the test that decides whether a system is needed, the incentive runs one direction. The test becomes a sales lead for the installation. A measurement-only firm has no system to sell, so it is paid the same fee whether your result is high or low. That is not a marketing promise. It is the reason the measurement is worth trusting.
Measure before you mitigate, and never let the same company do both.
The EPA treats these as separate steps for the same reason: test, confirm an elevated result, then mitigate if the confirmed level warrants it. Keeping the measurement independent is how you make sure the number driving a several-thousand-dollar decision was not produced by the party that profits from that decision.
| The conflicted model | The independent model |
|---|---|
| One firm tests and installs the system | An independent firm measures; a separate firm mitigates |
| Revenue depends on the test finding a problem | The fee is the same whether the level is high or low |
| The test is a lead for the installation | The measurement is the deliverable |
| The installer confirms its own work afterward | Post-mitigation testing is done by someone who did not do the work |
How radon is measured, and how to read the result
There are two kinds of measurement, and the right one depends on your timeline.
- Short-term testing. A device sits in the home for a few days, commonly two to seven, with the windows and doors kept in normal closed conditions. It is the fast option, useful for a real estate transaction on a deadline.
- Long-term testing. A device stays in place for more than ninety days. Because radon levels swing with weather, season, and how the house is run, a long-term reading gives a truer picture of the average you actually live with.
- Placement. The device goes in the lowest level of the home that people regularly use, away from drafts, exterior doors, and high humidity, so the sample reflects the air you breathe rather than a fluke corner.
- Confirmation. A single elevated short-term result is usually confirmed with a second test before anyone spends money on a system.
The Action Level
The EPA sets an action level of 4.0 pCi/L. At or above that number, the EPA recommends fixing the home. It also suggests that homeowners consider fixing between 2 and 4 pCi/L, because no level of radon is entirely without risk. A measurement report gives you your number against that benchmark, in writing, so the decision is yours and it is informed.

If a mitigation system is on your mind, a measurement comes before it, not after. You cannot size or justify a radon system without a confirmed level, and the confirmed level should come from a party that does not sell the system. This is the ordinary order of the work: measure, confirm if the first reading is elevated, and only then bring in a mitigation contractor if the numbers call for one.
AirMD handles the measurement and stops there. If your home tests below the action level, you have documentation and you have saved yourself a system you did not need. If it tests high, you have an independent, defensible number to hand a mitigation company, and a baseline to test against once their system runs. Either way, the number that starts the process was not written by the company hoping to sell you the fix.
Radon and a Naples home sale
Radon shows up in Florida real estate because state law requires a radon notice in real estate sale and lease contracts. The notice tells buyers and tenants that radon exists and can accumulate; it does not tell them the level in the specific home. That gap is exactly what a measurement fills.

For a buyer, a short-term test during the inspection period turns a signed disclosure into an actual number for the house. For a seller, a clean measurement is a dated record that answers the question before a buyer has to ask it. If the reading is elevated, both sides know it early, while there is still time to price mitigation into the deal instead of discovering it after closing. You can see the specific service and coverage on AirMD’s radon testing in Naples page, and the broader radon testing service page explains the measurement method in more depth.
A clean result is worth the test too. It documents your air on a specific date and tells you the paperwork you signed does not point at a problem in your home. When the firm that measured has nothing to sell you afterward, a low number is as trustworthy as a high one.
Frequently asked questions
Is radon a problem in Naples, FL?
It can be, and a county-level map cannot tell you whether it is a problem in your specific home. Radon levels depend on the soil under the house, the construction, and how the home is sealed and ventilated, so two homes on the same street can read very differently. Florida is not uniformly high or uniformly low, which is why the only reliable answer for a given address is a measurement rather than an assumption drawn from a map.
Does AirMD install radon mitigation systems?
No. AirMD measures radon levels and provides the report. It does not install mitigation systems and does not remediate. That separation is deliberate: the company measuring your air has no financial stake in whether you need a system, so its number is not shaped by the sale of one. If a confirmed measurement shows an elevated level, you take that independent result to a mitigation contractor.
What radon level is considered unsafe?
The EPA sets an action level of 4.0 pCi/L, meaning it recommends fixing a home that measures at or above that figure, and it suggests considering action between 2 and 4 pCi/L because no amount of radon is completely risk free. A measurement report places your home’s number against that benchmark so you can make an informed decision.
If you are weighing radon testing in Naples, start with the measurement and keep it independent. You can request a test through the Naples radon testing page, and you will get a number you can act on, whichever way it reads.
