Florida Radon Program  (rules, answers, certified businesses and individuals) for Bonita Springs Homeowners and Homebuyers


Florida radon testing rules: 

Florida Department of Health regulates radon measurement and radon mitigation in Naples, Marco Island, Bonita Springs, Estero, and all of Florida.Florida requires Naples or Bonita Springs persons certified for radon measurement “testing” to adhere to several protocols when placing radon tests.
Your Naples or Bonita Springs certified Radon Measurement person should choose a position where the detector will not be disturbed during the measurement period and where there is adequate room for the device. 
Florida requirements for placement of a radon test within a home include:

  1. The radon measurement (testing device) should not be within 12 inches (30 cm) of the exterior wall of the building, but, in no case, closer than 3 feet (90cm) to windows or other potential openings in the exterior wall.
  1. The radon measurement (testing device) should be at least 20 inches (50cm) from the floor, 4 inches (10cm) from other objects, and 12 inches (30cm)from the ceiling.The best radon measurements should not be made near drafts caused by heating, ventilating, and air conditioning vents, doors, fans and windows.
Your Bonita Springs or Naples certified radon measurement person should know that locations near excessive heat, such as fireplaces, in direct sunlight, and areas of high humidity should be avoided.
Air conditioning systems that recycle interior air may be operating in the Naples area.  Normal operation of permanently installed air-to-air heat exchanges may also continue during closed-house conditions.
If the home has a permanent radon mitigation systems already installed, it should be functioning during the measurement period. Turn it on, if off, 24 hours before testing.
Home should be in “Closed House Conditions”, 12 hours prior to and during a short term radon test.


Elevated Radon levels in Condo's are about 1 out of 2 (50%)

In our experience, it is not unusual for condos in Bonita Bay, Pelican Landing, The Brooks or anywhere else in Bonita Springs to have elevated radon levels.  We have had thousands of clients concerned about the radon levels in the Bonita Springs home they are buying but have never tested the home they have lived in for years “up north”.  Radon levels can be lowered by a FL DOH certified Radon Mitigation Business.

Bonita Springs Home Buyers should take "THE NATIONAL RADON TEST".

What to expect whenordering a radon test:

Professionals in Bonita Springs will perform a  “short term” radon test using a CRM (continuous radon monitor); which will give you hour by hour reading of your radon levels.  Professionals who use a Femto-Tech radon monitors will generally run a second passive test from “Air Chek” as a quality control test. Radon and Mold Professionals started doing this years ago, after we had a problem with our Radalink monitors.  Any mechanical device can have a “problem” so with a second test (quality control) we do our best to provide you with the best test we can. We have not used Radalink equipment for more than a decade now.  We switched to Femto Tech monitors and have been very happy with the results.We have performed over 13,000 radon tests in SW Florida including Bonita Springs.

For a “long term” radon test in Bonita Springs, we recommend an “Alpha Track”.  Experience has shown us that for radon tests between 90 days and one year, the Alpha Track is the way to go. Long term radon tests do not require your Bonita Springs home to maintain “closed house” conditions like the “short term” radon test does.

Radon testing guidance was originally produced by the US EPA in the mid-late 1980s. Their guidance was to conduct a screening test first using a short-term testing device and prior to deciding whether to mitigate, recommended a follow-up test. The follow-up recommendation included short-term and long-term options, depending on the amount of radon found during the screening measurement, meaning that a decision on the need for mitigation could take several months.

When the real estate community began to understand the need to include radon testing as part of home transactions, there was a realization that the EPA guidance wasn't real estate friendly because the majority of the transactions needed quicker turnaround to meet closing deadlines, etc. The EPA responded to the real estate community's request for a time-sensitive and released Protocols for Radon and Radon Decay Product Measurements in Homes in 1993, which included sections that were specific to real estate transactions. An abbreviated version of the real estate section has been published as a stand-alone guidance booklet, known as Home Buyer's Seller's Guide to Radon, which was last updated in January 2009. The EPA guidance essentially says to test once, either with an appropriate electronic Continuous Radon Monitor, or by deploying a duplicate pair of passive devices (i.e., charcoal-based devices). The recommendation on when to fix is based on the outcome of this testing strategy by saying that results of 4 pCi/L or more should result in the installation of a radon mitigation system. Therefore, there isn't really any guidance that incorporates second tests and how to handle the second result when reading through the real estate sections of the documents. The EPA continues to support a homeowner protocol of testing multiple times when there are not time constraints and in that guidance it would recommend averaging two results when two rounds of short-term testing has been performed and to install a radon mitigation system if the average was 4 pCi/L or more. ------------------------
The Florida Department of Health (DOH) operates a radon program, which includes a certification section. The DOH does provide guidance to radon professionals as well as to Florida residents regarding radon testing and mitigation, including all type of radon testing including real estate, general homeowner concerns, and well as mandatory testing required in many school, day care, foster home, licensing situations. I have had many conversations with Ms Gail Melvin, who runs the certification section of the FL Radon Program about their radon policies and on more than one occasion, Ms Melvin has indicated that their guidance for real estate transaction is that as long as the first radon test has been done properly, there is not need to perform a second test. Situations that could be considered improper include things like testing by a non-certified technician, device malfunction, protocol violation, extreme or unusual weather. However, in these scenarios a test would need to be deemed invalid in order to necessitate a second test. If the first test was valid and there are no reasons why the test should be thrown out, the decision whether to mitigate should be based on the first test alone.
I have searched the FL Radon Program website for written guidance that substantiates Ms Melvin's verbal guidance, and I have not found anything at this time. I did find the following paragraph on their FAQ page that seems to contradict the guidance that I have been given:
If your first test results were from a short term test (passive test), it is suggested that you perform another radon test in the same area. If you are in a time crunch (ie: for a real estate transaction) then perform a short-term test in the same place again. Then average the results of the 2 tests. If the average is below 4 pCi/L, then retest your home every 2 years. If the average is above 4 pCi/L, consult with a certified mitigator regarding your next step. If  you have the time available, it is suggested that you perform a long-term test as your second test. This test lasts over 91 days and provides an excellent measurement of the radon concentration in your home because it takes into account weather fluctuations and radon concentration fluctuations that occur in your home. If this result is over 4 pCi/L, consult with a certified mitigator regarding your next step. If the first testing of your home was with a long-term test and the result is greater than 4 pCi/L, it is suggested that you perform another short term test in the same area. If the results of both tests or the average of both tests are greater than 4 pCi/L, consult with a certified mitigator regarding your next step. If the result is less than 4 pCi/L, continue testing your home every 2 years.


What do I do if my test results are greater than 4 pCi/L?

Radon Guidance for Real Estate Transactions

Fri, 8 Jun 2012 15:32:26 -0400


I apologize for not getting back with you sooner, but I have been out of

the office.

The department has not adopted an official position on this issue, however, the Radon and Indoor Air program recognizes and supports the


1) As a state program charged with protecting public health with respect to radon exposure, we recognize the US EPA Homebuyers and Seller's testing protocols as the best method for determining radon risk under the artificial time constraints of a real estate transaction.

In that case of a real estate transaction and only a real estate

transaction, a radon mitigation decision can be made based on a test

that meets the real estate transaction testing protocols. Make one test and fix if elevated.

2) During radon testing for any purpose other than a real estate transaction, two tests should be made prior to performing radon mitigation.

3) When evaluating radon risks and exposures, a test can not be discounted, disqualified or ignored unless a failure to meet protocols or quality standards is identified.

4) The radon program recognizes that any short term radon test result, no matter what protocol is used, reflects long term averages with limited certainty. A long term test better reflects longer term average

radon levels and occupant lung cancer risk. When both the buyer and seller are amenable to solutions outside the constraints of the normal real estate transaction, we have offered the option of performing a long term test prior to mitigation when measured radon levels are within the current EPA guidance for long term follow-up testing for non-real estate testing and with mitigation funds placed in escrow.

WallRadon Testing, Inc. dba Radon & Mold Professionals is a Florida Department of Health Certified Radon Measurement Business (RB1938). We are NOT affiliated with any radon mitigation business. We are an independent radon testing business. We just test. We are NOT responsible for poor radon mitigation installation or lack of required permits.

Naples, Marco Island and Bonita Springs Homeowners, Buyers and Sellers should choose their Radon Mitigation Business with caution.  Protect yourself, insist on

CURRENT  "certificate of insurance" and copies of required permits.

  • Radon Mitigation System installationREQUIRESa permit in Collier County, Marco Island and Naples.
  • Buyers should have a copy of permit for radon mitigation system.


Certified businesses are required to report their activities.  A mitigation contractor must provide:

1) mitigation system labels, (name of company installing system)
2) a visual or audible device to automatically indicate system failure,
3) soil gas exhaust vents above the eave of the roof for active soil depressurization systems, and
4) written instructions on the operation and maintenance of the system.

The department recommends you review these requirements with the mitigation contractor before entering into a contract. If you have any questions about the radon businesses listed below or your radon mitigation system, you may contact the Bureau of Epidemiology, Radon Program by calling (800)-543-8279 or writing to 4052 Bald Cypress Way, Bin #A08, Tallahassee, FL 32399-1710.

We have performed thousands of radon tests in Bonita Springs and surrounding areas since 1999.
A couple of weeks ago we performed radon testing (inspection) in a Bonita Springs 3 story commercial building that until recently was a Real Estate office for well know national company.  Clients of this Real Estate Company rarely ordered radon tests when buying a Bonita Springs home or condo.  The office building was less than ten years old and the radon levels were elevated.  Elevated radon levels are the second leading cause of lung cancer according to the EPA. 
Hundreds if not thousands of homes in Bonita Springs have elevated radon levels, when buying you should have a radon test performed. 
It is a health concern but is best treated as a home repair and can be easily mitigated.
