Testing is the only way
to know if you and your family are at risk from Radon. The EPA and the Surgeon General recommend testing
all homes below the third floor for radon.
KROKER HOME INSPECTION P.L.L.C. recommends testing both Air and Water in New Hampshire. A Radon Air Test is usually performed in
the basement with doors and windows closed.
A Radon Water Test is recommended, particularly if the home uses a
Radon is a naturally occurring
colorless, tasteless, odorless radioactive gas.
The American Lung Association and the U.S. Environmental Protection
Agency (EPA) have identified exposure to Radon as the second leading cause of
lung cancer in the United States.
Radon is an invisible gas produced by the decay of naturally occurring
uranium in soil and water. Radon is a form of ionizing radiation and a proven
carcinogen. Lung cancer is the only known effect on human health from exposure
to radon in air.
Radon is found in outdoor air and in the indoor air of buildings of all
kinds. EPA recommends homes be fixed if the radon level is 4 pCi/L (picocuries
per liter) or more. Because there is no known safe level of exposure to radon,
EPA also recommends that Americans consider fixing their home for radon levels
between 2 pCi/L and 4 pCi/L. The average radon concentration in the indoor air
of America's homes is about 1.3 pCi/L. It is upon this level that EPA based its
estimate of 20,000 radon-related lung cancers a year. It is for this
simple reason that EPA recommends that Americans consider fixing their homes
when the radon level is between 2 pCi/L and 4 pCi/L. The average concentration
of radon in outdoor air is .4 pCi/L or 1/10th of EPA's 4 pCi/L
Levels vary from home to home,
development to development. Radon gas moves through small spaces in the soil and
rock. It enters a home through dirt
floors, floor drains, cracks in the foundation, cracks in the basement floor,
cracks in slab floors in homes without basements, holes for sump pumps, and
through hollow core block foundation walls.
The EPA Recommends:
• If you are
buying a home or selling your home, have it tested for radon.• For a new home, ask if radon-resistant construction features were used and if the
home has been tested.• Fix the
home if the radon level is 4 picocuries per liter (pCi/L) or higher. • Radon levels less than 4 pCi/L still pose a risk and in many cases may be
• Take steps
to prevent test device interference when conducting a radon test.
