Radon testing has become common in Real Estate transactions in
the Naples and Fort Myers area. When we began performing radon tests in 1999, if a company performed 6 tests a month
you were "busy". Since then the numbers have grown, we have performed over 23,000 radon tests. Many homes
/ condos have been purchased as investments and the wise investor has ordered a radon test. Many condos whether 2 story
structure or 27 story high rises have elevated radon levels. In fact the last few high rises build in the Naples - Bonita
Springs area had fresh air systems installed during construction partly to reduce radon levels. Single family homes
don't seem to have elevated radon levels near as much as condos do.

Your Naples, Bonita Springs, Marco Island or Ft Myers radon test
must be performed by someone certified by the Florida DOH if you are paying them.
Most radon tests for Real Estate transaction in Collier and Lee
Counties are performed using a continuous radon monitor (CRM) with the report giving you hour by hour readings of the radon
level, barometric pressure, temperature and humidity. This type of report helps determine if the home remained in "closed
house conditions" during the test as required by the FL DOH and EPA.
During the recession a few years ago many home inspectors became FL DOH certified to place and pickup radon tests
in the need to supplement lost income. Some of these inspectors use a passive radon test similar to what we use to test
schools and assisted - living facilities. A passive radon test only provides the client with one number, the average
radon level during the test which is normally 48 hours. A passive test can be carried outdoors during the test or doors
and windows can be left open skewing the test results and no one would know. This is a good test (AIR CHEK - radon.com - best), inexpensive but can be "tampered with" and you wouldn't know.
Common long term radon tests
tests can be long term (90 days to 12 months) or short term (usually 2 to 4days). Short term radon tests require
"closed house" conditions, doors and windows kept closed, brief entrance and exits allowed. Long term radon
tests allow you to have doors and windows open as you normally live. Since radon levels fluctuate up and down,
the longer the test the more conclusive the results. Homes typically have a lower air pressure than outdoors (negative
pressure) causing radon gas, mold spores, pollen etc to be "sucked" into the home. Having doors and
windows open lowers the radon level inside the home / air pressure equals the outdoors preventing the "sucking in".
Radon tests must be performed (placed & PICKED up) by a person certified to do so by the Florida Department
of Health and the report must come from aFLDOH certified Radon Measurement Business.

"The only way to know is to Test"
"Elevated radon levels have even been found on upper floors of High Rises in Collier & Lee"
Radon is a radioactive gas that has been found in homes all over the United States. It comes from the natural breakdown
of uranium in soil, rock and water and gets into the air you breathe. Radon typically moves up through the ground to the air
above and into your home through cracks and other holes in the foundation.
Any home can have a radon problem. This means new and old homes, well-sealed and drafty homes, and homes with or
without basements. In fact, you and your family are most likely to get your greatest radiation exposure at home. That is where
you spend most of your time.
How do I know if there is radon
in my home? You cannot see, feel, smell, or taste radon. Testing your home is the only way to know if you and your family
are at risk from radon. The EPA and the Surgeon General recommend testing for radon in all homes. The EPA also recommends
testing in schools. You cannot predict radon levels based on state, local, and neighborhood radon measurements. Do not
rely on radon test results taken in other homes in the neighborhood to estimate the radon level in your home. Homes which
are next to each other can have different radon levels. Testing is the only way to find out what your home's radon level
is. What can I do to protect myself and my family from radon?
The first step is to test your home for radon, and have it fixed if it is at or above EPA's Action Level of 4 picocuries
per liter. How can radon affect people's health? Almost all risk from radon comes from breathing air with radon
and its decay products. Radon decay products cause lung cancer. The health risk of ingesting radon, in water for example,
is dwarfed by the risk of inhaling radon and its decay products. They occur in indoor air or with tobacco smoke. Alpha radiation
directly causes damage to sensitive lung tissue. Most of the radiation dose is not actually from radon itself, though, which
is mostly exhaled. It comes from radon's chain of short-lived solid decay products that are inhaled and lodge in the airways
of the lungs. What does radon do once it gets into the body?
of the radon gas that you inhale is also exhaled. However, some of radon's decay products attach to dusts and aerosols in
the air and are then readily deposited in the lungs. Some of these are cleared by the lung's natural defense system, and swallowed
or coughed out. Those particles that are retained long enough release radiation damaging surrounding lung tissues. A small
amount of radon decay products in the lung are absorbed into the blood.
U.S. Surgeon General Health Advisory
radon gas is the second-leading cause of lung cancer in the United States and breathing it over prolonged periods can present
a significant health risk to families all over the country. It's important to know that this threat is completely preventable.

bring our own table and place the monitor in the best location. We do not put our equipment on the homeowner's furniture.
2 tests at once, we use a passive charcoal test as a quality control test with every monitor.
The charcoal test is the same type we use in schools and assisted living facilities, where we have hundreds of rooms
We always leave a copy of the EPA's Homebuyers &
Sellers Guide to Radon with every radon test as required.
We use the Femto-Tech monitor, it is a $4,500 monitor (we do not use the inexpensive monitors such as sun nuclear monitor, used
by many home inspectors)
This unit records climate measurements.
is very important, it alerts you if someone accidently left a door or window open during the test.
Climate measurements tell us about the conditions while the test is being performed
and discourages tampering with closed home conditions.
Adminstrative Code: 64E-5.1203 General Provisions (1)
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."
Collier and Lee County requires radon testers to have an occupational license for the county the test is in. The Counties had 5
people listed with an occupational license for radon testing last year.
County occupational license office says:
"You cannot get an
occupational license for radon testing unless you are certified by the FL DOH to test."
The person placing and / or picking up a radon testmust be FLDOH certified and have an occupational license for radon testing (occupational license for
home inspections does not qualify).
