WHAT IS RADON
Radon is a radioactive gas produced naturally by the
decay of uranium and radium. Radon is odorless, colorless, and
undetectable by the human senses. In the soil, as these elements
decay, radon gas is produced. Radon easily moves in homes
through cracks and other openings. Once into the home, radon has
less air to mix with, and may build up to dangerous levels.
Radon decay
products or the radioactive particles can be inhaled. Once
inhaled, the particles stick to your lungs and release radioactive
energy. The radioactive energy can cause damage to the lung
tissue. Extended exposure to high levels of radon can increase the
risk of lung cancer.
Radon is measured in picocuries of radiation per
liter of air (pCi/L). The EPA has set the radon standard (action
level) to 4 pCi/L. When radon levels are above 4 pCi/L, action
should be taken to reduce the level.

TESTING FOR RADON
The only was to
determine if your home has a high radon level is to test for it.
There are two different types of test kits available to test for radon.
The short-term test kit is
left in the home for a period of a minimum of 2 days (depending on the
recommendations from the manufacture). The results of this test
provide the homeowner with an idea of the potential for a problem in
the home. The ideal time for testing is during the fall and winter heating season, when
the home is closed up.
The long term test
kit is left in in the home for a period of up to one year (depending
on the recommendations from the manufacture). The results of
this test provides the homeowner with the annual average exposure of
radon. It is strongly suggested that the long term test never be
used unless a short term test kit has been done first.

TO GET RADON TEST KITS
The ideal time to test for radon is during the winter months, when the
windows and doors are closed. You can
purchase a radon test kit by contacting the Regional Radon Information
Center (RIC). Call the toll-free number
1 (888) 569-7236 or
1 (888) LOW-RADON and you will be routed to the
appropriate RIC. Or

WHAT DO THE RESULTS MEAN?
The US EPA standard is 4.0 pCi/L.
Results are less than
4.0 iCi/L - no further action is necessary.
Results greater than
4.0 pCi/L and less than 8.0 pCi/L - it is recommended to conduct a
long term test to determine the annual average exposure. If the
results from the long term test is above 4.0 pCi/L, efforts should be
made to reduce the radon level.
Results greater than
8.0 pCi/L - it is suggested to take a second short term test to
verify that the first short term test is accurate. If the
result of the second test are similar to the first test, action
should take place to reduce your exposure to radon in your home.

MOLD
Molds are small organisms that are found almost
everywhere, inside and outside your home. Many molds are
beneficial to the environment because of their ability to breakdown dead
material. However, in large amounts, certain types of mold
can present a concern for some individuals. Allergic symptoms,
similar to the symptoms caused by plant pollen, can develop in sensitive people.

options, landlord/tenant issues and hiring a contractor click on the
