What is Radon?
RADON is a cancer-causing radioactive gas. You cannot see, smell, or taste it, but it may be a
problem in your home. Radon is estimated to have caused thousands of deaths each year. You
can fix a Radon problem. Testing is the only way to know if you and your family are at risk. Radon
enters the home through solid cracks in floors, construction joints, cracks in walls, gaps around
suspended floors and service pipes, cavities in walls, and even the water supply. Radon affects
all types of homes, old, new, single story, all floors of a hi-rise building, and homes without
How does Radon enter my home?
Radon is a radioactive gas that has been found in homes all over the US. It comes from the
natural breakdown of uranium in soil, rock, and water, & 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. Radon can also enter your home through well water. Your home
can trap the Radon inside.
Any home can have a radon problem. This means new & old homes, well-sealed & drafty
homes, and homes with or without basements.
The only way to know your homes radon levels is to test for it.
How does Blue Line Environmental Services test for Radon in my
1. BLES uses Radalink monitors. They are calibrated and checked every 6 months to
exceptionally high standards. The monitor records information every hour ( not video or audio)
this includes humidity, temperature, current Radon levels as well as if the unit is tampered with.
What is the procedure used for testing my home for Radon?
1. First, call to schedule your appointment with BLES. After scheduling, notify the occupants the
importance of the Radon testing and importance of following the instructions that will be
2. The home should be maintained at closed-house conditions 12 hours prior to the test. This
means that the windows and doors shall be closed. Normal entry and exit is okay. The AC may
run normally. If you have a window mounted AC, the setting should be set to “Recirculate”. If a
radon reduction system is present, insure the unit is ON.
3. When Chuck arrives, he will do a walk-through evaluation of your home. He will be looking for
the best location to place the Radon monitor as well as verifying “Closed House Conditions”
have been met.
4. The monitor will be placed on a small table (provided by BLES) and activated. The monitor
and table should not be touched. Do not relocate the monitor as it has tamper detecting features
and will nullify the test.
5. The monitor must operate for a minimum of 48 hrs. We will work with your schedule to
arrange for the unit(s) retrieval. When retrieved, the information from the monitor will be
immediately downloaded to the computer and sent to the Lab in Atlanta for evaluation.
5. The report typically will be returned to you within 24 hrs.
7. The report will show the homes average level of radon as well as the current levels of radon
every hour the test has been run. As always, if you have any questions, please call BLES.

When receiving your report, the average level of radon will be highlighted. The EPA’s
recommended action level for mitigation is 4.0 picl and above.

Can I fix a Radon problem?
YES! A radon mitigation system installed by a licensed mitigation
company can lower Radon levels to an acceptable level. Systems are
relatively inexpensive (approx. 1500-2500) installed. More information
can be found and be presented by the mitigation company. Below is the
Florida Dept of Health list of Licensed Mitigation Companies.
We know that radon levels can only be determined by testing for it.
