Naples & Ft Myers Radon Test Info

Collier County which includes Marco Island and Naples require a permit to install a radon mitigation system to lower the elevated radon levels in a home.  Electrical and mechanical work must meet county codes.

Apparently some radon mitigation businesses try to avoid the mechanical and electrical inspections required by Naples, Marco Island and Collier County.  Reputable companies can and will get the appropriate permits when installing a radon mitigation system in your Collier County home.

Radon Testing in Naples

Florida requires Naples  persons certified for radon measurement “testing” to follow several protocols when placing radon tests.
Your Naples Radon “tester” should choose a position where the radon test 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:
  • Your radon test should not be within 12 inches (30 cm) of a outside wall of the building, but, in no case, closer than 3 feet (90cm) to windows or other potential openings in the exterior wall.
  • A short term radon 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.

Your  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.

Home should be in “Closed House Conditions”, 12 hours prior to and during a short term radon test.
Air Condition systems should be in the “Auto” position.  Radon Mitigation system should be on.


Radon Gas

Radon gas comes from the natural breakdown of uranium in the soil, rock and water and gets into the air you breathe.  Radon typically moves up thru the ground to the air above and into your home thru cracks and other holes in the foundation.  Radon can also enter your home from well water. Your home can then trap radon inside for you to breathe.

Radon is a cancer-causing radioactive gas.
You cannot see, smell, or taste radon. But it can be a problem in your home.  When you breathe air containing radon, you increase your risk of getting lung cancer.  The surgeon General has warned that radon is the second leading cause of lung cancer in the US.
If you smoke and your home has high radon levels, your risk of lung cancer increases dramatically.

Elevated Radon is a serious health concern but also just a home repair. 
This seems to be the best approach to elevated radon levels for homeowners and home buyers.  You would not move or not buy a home if it needed new cupboard doors, so have the radon levels "mitigated" if they are tested and found to be elevated.
Surgeon General of the United States Health Advisory
  • Indoor radon gas is a national health problem.
  • Radon causes thousands of deaths each year.
  • Millions of homes have elevated radon levels. 
  • Most homes should be tested for radon. 
  • When elevated levels are confirmed, the problem should be corrected.
You cannot predict radon levels based on state, local and neighborhood radon measurements.  You should not rely on radon test results in other homes in the neighborhood to estimate the radon level in your home.  Two homes side by side can have very different radon levels.
The only way to know your homes radon level is to test.

The EPA recommends knowing the radon level of any home you consider buying.
If the home has elevated radon levels, have the home mitigated.  You should know that it is much cheaper to test for radon than to fix elevated radon levels.
Public awareness has been growing about Radon and it's effects on human health, naturally Radon testing in Real Estate transactions is becoming much more common. One company is the "South" did about 300 radon tests in a year for Real Estate transactions four years ago, now they perform radon testing in about 2000 homes a year for buyers.

Nearly 1 out of 15 homes in the U.S. is estimated to have elevated radon levels (4pCi/l or above). 
Elevated Radon levels can be found in most any home, even High Rise condo's on the 20th floor.  You do not have to have a basement to have elevated radon.  Elevated radon levels can be found in all parts of the country.  In Florida about 1 out 7 homes tested have elevated radon levels, some counties in southwest Florida "1 out 4 homes tested have elevated radon levels" (FL DOH).  New homes and old home, well sealed homes and drafty homes, any home can have a radon problem.

There are dozens of places for information on radon, we have tried to list the most informative ones.  We also have a "news" section at the bottom of this page, which may be helpful.

Radon Risks & Health Effects (CLICK HERE)


There are dozens of radon test devicies, some are short term and others are long term. 

  • Short term radon tests remain in home/structure from 2 to 90 days. 
  • Long term radon tests remain in home more than 90 days.
  • For Real Estate Transactions the short term is the quickest way to test a home

"Active" Radon Tests and "Passive" Radon Tests

  • Active radon tests are Continuous radon monitors, which are electronic, usually with hour by hour reading of the homes radon levels.  CRM’s should be calibrated annually.
  • Passive radon tests  just give you one number , the radon level (average) for the test period, minimum of 48 hours (EPA).

List of Radon Devices:


The continuous radon monitor is popular for the Real Estate market because some also measures the temperature, humidity, and barometric pressure.  This helps detect any unusual readings of radon, temperature and humidity caused by closed house conditions not being met during the test period.  For short term tests the home must be in closed house conditions 12 hours prior to the test and during the test.  Brief entry and exit are allowed, but doors and windows must remain closed.   HVAC  (furnace & AC) must be in the Auto mode, operated normally.    Occupants can live in the home during the test period.

For homeowners that want to test their own home or markets that don’t justify the expensive CRM’s, the passive tests work very well for homeowners and professional testers/inspectors.

The EPA “Home Buyer’s and Seller’s Guide to Radon” is good reading for homeowner’s who are wanting to test their home and required reading for the professional radon tester.  ( COPY availible on link above)

Active Radon Test Devices

Common Radon monitor used in Naples FL

Femto-Tech monitors are use world wide by radon professionals. Femto-Tech monitor has tilt sensors and measures the temperature, barometric pressure and humidity also.  This reduces “cheating” in real estate deals and helps indicate if someone accidentally left a door or window open during the test.  At over $4000.oo each you don’t have to plug them, batteries are good from one annual calibration to the next.  Femto-Tech also has a lease program for professionals. http://www.femto-tech.com

The Femto-Tech, Inc. model CRM-510LP is a precision airborne alpha radiation detection instrument based on the same field proven pulsed ion chamber technology of previous models R210F and RS410F. Due to a unique patented electrometer and open grid probe design, the model CRM-510LP is highly suited for a wide range of radon measurement applications. Because of the low current requirements of the electrometer detector and on-board computer, the model CRM-510LP is truly a portable self-contained continuous radon monitor that can read and store test data for eight days of stand-alone operation.

“After performing over 20,000 tests in homes for elevated radon levels using a variety of tests. In our humble opinion the Femto-Tech is at the top of the food chain when it comes to the CRM’s.   Combine the Femto-Tech with the 3 page color report with graphs etc. from Air Chek, Inc. and you have a great, easy to read report delivered on line for a client.”

Radalink monitors are popular with home inspectors across the country. (The big green box) Radalink Monitors can detect unusual readings of radon, temperature and humidity caused by opening the windows. Tilt and power sensors, so if someone unplugs the power or moves it you know. It has hourly barometric pressure readings to help detect unusual radon levels due to extreme weather conditions.

Sun Nuclear / Honeywell
The inexpensive Sun Nuclear / Honeywell monitors are very popular with inspectors everywhere.  Most do not record climate conditions …. temperature, humidity, & barometric pressure.  This is a good monitor for the inspector who wants to upgrade from the passive test to a monitor for Real Estate inspections.

Passive Radon Tests

Homeowners or professionals testers with a small market generally use a passive radon test.  When professionals test schools, large multi-living complexes, assisted living facilities they use passive tests.  There are many test devices on the market, here are just a couple of examples.

  • Short term tests …. 48 hours to 90 days
  • Long term tests …...90 days to a year. 


Short Term Test:


One of the most simple to use with reliable results is from Air Chek, Inc. www.radon.com

Long term test:   


The Alpha Track from RSSI is very popular for homeowners and radon mitigation warranty tests.  Tests are in the home for more than 90 days, and you do not have to maintain closed house conditions.  (look at EPA's Homebuyers and Sellers Guide to Radon)


Long Term radon tests used in Naples homes
At least 90 days for good test

“RSSI's alpha-track monitor has other advantages. Unlike short-term monitors, the alpha-track is unaffected by heat, humidity or delays in return to the lab. RSSI's monitor is more accurate than other alpha-track monitors because of its larger chamber volume and detector size. The monitor's test material is retained by RSSI as a record that can be re-analyzed at any time.” …. RSSI

Here are some brief descriptions of some of the radon systems from RMS, for more detailed information go to the RMS web site; www.radonfix.com .
Mr. Gene Yacobacci from Radon Mitigation Services is one of the most experienced radon mitigators in Florida.  He has installed thousands of radon systems tru out Florida and other states.


In many areas a "Heat Recovery Ventilator" (HRV) or  an "Energy Recovery Ventilator" (ERV) is being used to lower radon levels.  Newer homes are sealed "tighter" and many new building products produce indoor air quality problems.  The ERV and the HRV help to improve the homes air quality and in many cases also reduce the radon levels.
The HRV & ERV is a type of mechanical equipment that has a heat exchanger combined with a ventilation system for providing controlled ventilation into a home or building.
Dozens of companies produce HRV's & ERV's, among them are Lennox, Fantex, RenewAire, and Stirling Technology, Inc..
For more information on Energy Recovery Ventilators and Heat Recovery Ventilators look at the links below.

Many States have regulations for Radon Businesses / Professionals.  You are advised as a consumer to know your state's requirements, if any.
An example is Florida & Nebraska below, and a news item from Pennsylvania.

Florida Adminstrative Code: 64E-5.1203 General Provisions  (1)

"Begining January 1, 1989, no person may test for or mitigate the presence of radon in Florida for a fee or other renumeration unless such person has been certified."


"It is a violation of Chapter 404, Florida Statutes and Chapter 64E-5, Florida Administrative Code to provide radon services without being currently radon certified by the Florida Department of Health. Specialists and technicians must provide radon services only through affiliation with a Florida certified radon business. Businesses and individuals will be fined for non compliance."  FL DOH

Consumers should be alert,  it's common sense to ask to"see" a contractor's license or required certification.
Wednesday, September 14, 2005: Radon services performed without certification, state says A 50-year-old Susquehanna Twp. man has been charged with conducting radon testing without proper certification from the Pennsylvania Department of Environmental Protection. Criminal charges were filed against Richard Denman of the 400 block of North 32nd Street, owner and operator of a home inspection business called North Systems.

What are the causes of lung cancer?

Dr. Richard T. Bosshardt | Special to the Sentinel
Posted December 3, 2006

Question: If I don't smoke, what are my chances of getting lung cancer? After reading about Dana Reeve, the wife of Superman actor Christopher Reeve, I learned of several others who got lung cancer but never smoked. Is this rare?

Answer: It depends on your definition of rare. Every year, around 170,000 people in this country develop lung cancer. Although 90 percent have a smoking history, the remainder are nonsmokers -- about 17,000 people per year. Not common, but not rare either.

Of that 10 percent, studies show nonsmokers who live with smokers have a 25 percent higher chance of developing lung cancer compared to other nonsmokers. Breathing secondhand smoke over time results in 3,000 lung-cancer deaths each year.

After secondhand smoke, the second-highest risk factor in developing lung cancer for nonsmokers is exposure to radon gas.

Radon gas is a tasteless, colorless, odorless gas that results from the decay of radioactive uranium, which is found naturally in rocks, soil and water. Radon gas occurs naturally in the air and ground and can enter homes through cracks in the foundation, pipes and other openings.

The U.S. Environmental Protection Agency estimates that as many as 1 in 15 American homes may contain dangerous levels of radon gas. You can test for the gas yourself by purchasing a kit available in most hardware stores, or you can have it done for you by contacting the local EPA office for information. You also may go to www.doh.state.fl.us/Environ ment/community/radon.

If your home has high levels, certain measures can reduce them by up to 99 percent. The most common one is installing effective ventilation systems to remove the gas to the outside. An estimated 15,000 to 22,000 lung-cancer deaths a year are the result of radon gas. Smokers exposed to radon have a much higher lung-cancer risk than nonsmokers.

Asbestos exposure is another risk factor in nonsmokers. Although it is no longer routinely used in construction and insulation, plenty of asbestos remains out there, especially in older buildings. Nonsmokers exposed to asbestos increase their lung-cancer risk fivefold. Smoking plus asbestos exposure increases the risk to a much greater degree than either smoking or asbestos exposure alone. In addition to the typical lung cancers, asbestos exposure puts one at risk for an unusual cancer of the lining of the lung, called a mesothelioma. Even a few months of asbestos exposure can greatly increase this cancer risk.

Air pollution from automobiles, industry and power plants also can increase risk. Some regard long exposure to highly polluted air as equivalent to secondhand-cigarette-smoke exposure. Air pollution causes an estimated 2,000 lung cancer deaths per year.

People with certain chronic lung diseases, such as emphysema, also are at greater risk of lung cancer.

Beyond exposure to environmental risk factors, some people have a unique and innate predisposition to develop lung cancer. It is probably inherited genetically. If you have family members with lung cancer, this may mean you might be at greater risk. Individual susceptibility to cancer-causing agents can vary widely. This is probably why some people who smoke one or more packs of cigarettes a day for years don't get cancer, while others do.
