INTERPRETING YOUR TEST RESULT
The US EPA action level for indoor radon is 4.0 pCilL. The EPA recommendation for
results in this range (2.0 to 3.9 pClL) is to conduct further tests to determine the true
annual average, ideally with a long-term test kit. If the result remains between 2 and 4 therc
is little short-term risk, but you should consider fixing your home. Additionally, if you
make any structural changes or start to use a lower level of the building more frequently,
you should test again.
You may be able to obtain additional information about radon related subjects by calling
your state radon officer at 800-846-3986.

Your Test Result
This result has been rounded to one-tenth (0.1) of a
pCi/L (picocurie per liter). This test result reflects
the amount of radon measured in this sample
AF'TER it arrived at our laboratory. All analysis
calculations are automatically adjusted to reflect
the length of test, the amouni of iroisture in the
sample, temperature, time from the end of test, and
the amount of radiation measured. If your test kit
was used prior to the Use By date, ALL the testing
protocols and instructions were carefully followed,
and the data recorded properly on the test packet,
then it is reasonable to assume this is an accurate
assessment of the average level of the radon this
sample was exposed to during the test period.
Health Risks
The primary health risk from long{erm exposure to
radon is lung cancer. The risk of developing a lung
cancer from radon exposure depends both on how
much radon is present and how long you are
exposed to radon. The higher the radon level or the
longer the time of exposure, even if the levels are
relatively low, the greater the risk. EPA has set an
Action Level for radon at 4 pCrlL1, however radon
concentrations less than 4 pCill- still pose some
health risks. The Indoor Radon Abatement Act set
a goal for indoor radon concentrations to equal the
amount of radon found outdoors, which is
estimated to be - 0.4 pCi/L.
Conducting Follow-up
Measurements
USEPA protocol describes two general types of
radon measurements: short-term tests conducted
from 48 hours up to 90 days, and long-term tests
that last from 91 to 365 days. Your first test
(initial/screening) should be a short-term
'worst-case' screening to see if there is a potential
for high exposure to radon. Screening tests should
be conducted under closed-building conditions, in
the lowest lived-in area in the house, because the
highest concentrations of radon will usually be
found in a room closest to the underlying soil.
Tests made under these conditions are less likely to
miss a house with a potential for high
concentrations. On the other hand, ifthe results of
worst-case screening tests are very low, there is a
high probability that the average annual
concentrations in the house are also low.
(Continued on Back)
Most states have a radon office to assist citizens with general questions about radon and radon reduction techniques.
Many states maintain a list of licensed or certified radon testing and mitigation professionals. You can visit
www.state-radon.info to find the list of state radon contacts, as well as links to additional radon resources in your area.
Conducting Follow-up Measurements
The higher your initial (screening) tests, the sooner you should
conduct follow-up measurements. The EPA states that you
should retest the same location that was tested initially.
For additional or follow-up testing, make sure at least one test is
conducted in the lowest lived-in level of the home. Also choose
regularly used rooms, such as family rooms, dens, playrooms, or
bedrooms. A bedroom on the lower level may be a good choice,
because people generally spend the most time in their bedrooms
(approximately one-third of the year). If there are children, it may
be appropriate to test their rooms or other areas where they spend
a lot of time, especially at the lower levels. All short-term
follow-up tests must be conducted under closed-building
conditions. If closed-building conditions cannot be maintained, a
long-term measurement conducted under normal living conditions
could be used to help estimate average annual exposures.
Tests should not be conducted in a kitchen or a bathroom
because high humidity, exhaust fans, and other factors can
adversely affect the test results. Tests should not be conducted in
storage areas or laundry rooms, because relatively little time is
spent there. Although radon in water may be a contributor to the
concentration of airborne radon, radon in air should be confirmed
before a test for radon in water is performed.
It is recommended that before spending any time or money on
radon mitigation, one should conduct multiple (two or more) tests
to be certain there is a need. A few more tests will most certainly
cost considerably less than any mitigation work.
If follow-up measurements have confirmed that the average
annual level of radon is equal to or greater than 4 pCi/L, the
USEPA recommends that the building or home be mitigated for
radon. Consider also that a future buyer is likely to demand that
the building pass a radon test before purchasing.
Variations in Radon Levels - What can affect your test results
and why it may be important to conduct confirmation tests.
When tests are performed in different seasons or under different
weather conditions, the initial screening and follow-up tests may
vary considerably. Radon levels can vary significantly between
seasons, so different results are often expected. Even during
normal weather, indoor radon levels may rise and fall by a factor
of two on a daily cycle; for example, from 5 pCi/L to 10 pCi/L in
24 hours. During rapidly changing or stormy weather, the levels
may change more dramatically.
Ifyou are comparing tests, or are averaging a series oftests, bear
in mind that any radon test returns only the average of the levels
present during a specific period of time at the precise location of
the test. Conditions during a different test period or at a different
location in the building are expected to be different.
Test results can also vary if the radon test instructions were not
carefully followed. A laboratory measuring radon in samples
taken outside the lab must rely on the person conducting the
test. For example, the wrong starting or ending date of a test will
significantly affect the calculated result. The location of each
radon test can also influence the result. For example, a test placed
in the blowing air stream of a fan is likely to collect more radon
than it would under normal conditions. Also, three tests conducted
in one home, but in three different rooms, would be expected to
have at least slightly different test results.
Test results from a properly used activated charcoal test will more
closely reflect the average radon concentrations over the last three
to four days ofthe test period. This happens because the radon
collected by the activated charcoal has a radioactive half-life of
only four days. This means, for example, over one-half of the
radon collected during the first three days of a seven day test
'died'before the test ended.

PERFORMING RADON TESTS FOR A RBAL ESTATE TRANSACTION
EPA guidelines recommend that at least two short-term tests should be conducted, either together or sequentially, in the lowest level of the building usable by the
buyers. If the average of all the tests is 4 pCi/L or more, the recommendation is to have the building mitigated by a certified professional. If the average is below
4 pCr/L, then no further action is necessary at this time, although testing in the future is recommended. It is highly recommended that any property transaction
tests be conducted by a certified radon professional. To locate a listed or certified radon tester, contact your state radon office (Wy_:y-Slglggglqigfo) or go to
www.nmn.info to download a list of professionals certified by the National Radon Proficiency Program (NRPP).
