How Do I
Check For Radon?
| Conduct
radon testing in
the lowest
lived-in level
of your home.
Tests should be
placed in a room
that is
regularly used.
Avoid testing in
bathrooms or
kitchens because
moisture can
affect the
accuracy of
tests.
If
you are
considering
selling your
home, test for
radon as soon as
possible to
avoid the time
constraints of
the real estate
transaction
process.
Step
1. Take a
short-term test
(2 to 90 days
long). If your
result is 4
pCi/L or higher
take a follow-up
test
Step
2. Conduct a
follow-up test
with either a
long-term test
(90 days to one
year) or a
second
short-term test.
Step
3.
If you followed
up with a
long-term test:
consider fixing
your home if the
result is 4
pCi/L or higher.
If you followed
up with a second
short-term test:
consider fixing
if the average
of your first
and second tests
is 4 pCi/L or
higher. |

How
Dangerous is Radon?
- Next
to smoking, radon is
the second leading
cause of lung cancer
The
Surgeon General has
warned that radon is the
second leading cause of
lung cancer in the
United States, second
only to smoking. The
U.S. EPA has established
an "action
level" of 4
pCi/L (4 pico curies per
liter of air). If your
home has a radon level
of 4pCi / L or greater
EPA recommends that you
fix the home. The
average indoor radon
level is estimated to be
1.3 pCi / L , 0.4 pCi /
L is normally found in
the outside air.
Remember the ONLY way to
know if you have a
problem is to test. The
EPA recommends
that you hire a state
certified company that
is trained to test and
remove high levels of
radon. For more

How
Does Radon Enter the
Home?
- Radon entry
into buildings
Radon moving
through soil pore
spaces and rock
fractures near the
surface of the earth
usually escapes into
the atmosphere.
Where a house is
present, however,
soil air often flows
toward its
foundation for three
reasons: (1)
differences in air
pressure between the
soil and the house,
(2) the presence of
openings in the
house's foundation,
and (3) increases in
permeability around
the basement (if one
is present).
In constructing a
house with a
basement, a hole is
dug, footings are
set, and coarse
gravel is usually
laid down as a base
for the basement
slab. Then, once the
basement walls have
been built, the gap
between the basement
walls and the ground
outside is filled
with material that
often is more
permeable than the
original ground.
This filled gap is
called a disturbed
zone.
Radon moves into
the disturbed zone
and the gravel bed
underneath from the
surrounding soil.
The backfill
material in the
disturbed zone is
commonly rocks and
soil from the
foundation site,
which also generate
and release radon.
The amount of radon
in the disturbed
zone and gravel bed
depends on the
amount of uranium
present in the rock
at the site, the
type and
permeability of soil
surrounding the
disturbed zone and
underneath the
gravel bed, and the
soil's moisture
content.
The air pressure
in the ground around
most houses is often
greater than the air
pressure inside the
house. Thus, air
tends to move from
the disturbed zone
and gravel bed into
the house through
openings in the
house's foundation.
All house
foundations have
openings such as
cracks, utility
entries, seams
between foundation
materials, and
uncovered soil in
crawl spaces and
basements.
Most houses draw
less than one
percent of their
indoor air from the
soil; the remainder
comes from outdoor
air, which is
generally quite low
in radon. Houses
with low indoor air
pressures, poorly
sealed foundations,
and several entry
points for soil air,
however, may draw as
much as 20 percent
of their indoor air
from the soil. Even
if the soil air has
only moderate levels
of radon, levels
inside the house may
be very high.

What
is Radon?
- Radon
is a radioactive gas
that is found in
every state in the
U.S.
It silently enters
your home through
the soil. You
can not smell,
taste, see, or feel
radon.

What
Makes RadonAmerica
Qualified?
- RadonAmerica
is certified to
provide both
measurement and
removal of cancer
causing radon.
top
My
neighbor checked for
radon and his house is
ok, does that mean my
house is ok?
- No,
radon can be low in
the neighbors house
and high in yours.
top
When
is the best time to
check for radon?
- Anytime,
but many people
check radon before
purchasing a
house.
Then you can
negotiate with the
seller to remove the
high radon before
the home is
purchased.

How
is Radon Measured?
- There are
several accepted
methods to measure
radon.
RadonAmerica.com
uses highly
accurate, calibrated
electronic monitors
that are EPA
approved.
top
How
high can the Radon be
before I take action?
- EPA
recommends that if
your results are 4
pico curies or
higher that you take
action to reduce the
levels of Radon in
your home.
top
If the
Radon is high, what
should I do?
- EPA
recommends that you
call a qualified
Radon
contractor.
- A qualified
contractor has been
trained to
efficiently lower
the radon in your
home.
RadonAmerica
guarantees that when
we install the
recommended system
your radon level
will be below the
EPA recommended
maximum. (4 pico
curies)

How
much does it cost to
measure?
top
How
much does it cost to
lower Radon levels?
- Normally
between $800 and
$2500 depending on
the home design,
soil conditions, and
the age of the home.

long does it take to
