Radon
Continued from previous page
worse than not knowing.
I got my test back and my
reading is elevated what
now? Who do I call? How do
I know they are reliable?
First you should use a Certified
Radon Mitigator; they have had
the classroom and field training
experience and have passed a
very comprehensive exam.
In the U.S. there are two certifying agencies and in some
states the state certifies mitigators as well.

Pick your state from the drop
down menu and find a few local Mitigators, you may want
to check an adjoining state as
well, if you are close to a state
line.
In Canada:

List/cnrpp_crmt.html
Scroll down through the list to
your province and find local
mitigators.
Make a few calls to get references, ask for a copy of their
contract, are they insured?
Check out their websites. Who
are you most comfortable
with? Lowest price will quite
often result in lowest quality
workmanship and materials.
This is a very good checklist
for comparing contractors.

Most mitigators will recommend an Active Soil Depressurisation (ASD) system,
unless you have marginally
elevated radon and other air
quality issues in the home. In
that case they may recommend a Heat Recovery Ventilator (HRV) that is specially
designed for radon reduction.
These HRV systems designed
for radon reduction come with
an energy penalty and ongoing
maintenance costs.
By far the most economical
and commonly recommended
ASD system (about 90%) is
a Sub Slab Depressurization
(SSD) system. SSD systems
depressurize the soil under
your slab stopping the radon
from coming into your home
and put it outside where the
radon was trying to go anyway.
Acceptable design of SSD
radon mitigation methods in
Canada and the US are very
different, so be careful you are
getting U.S. or Canadian information off the internet if you
are researching what design is
acceptable for your building.

January is Radon
Action Month in
the U.S., test your
home for radon
and get it fixed
if your levels are
elevated. The life
you save may be
your own!
