What is Radon?
Radon (Rn) is a colorless, odorless,
radioactive gas that occurs naturally in the soil.
Why is it a Concern?
In the outdoors, radon is harmless. But when
it enters a building it becomes concentrated. Prolonged exposure to high
levels of radon can cause lung cancer. In the United States alone,
up to 22,000 deaths per year are attributed to radiation exposure
emanating from homes. Some British researchers believe that they have
found a relationship between radon exposure and other disorders such as,
asthma, allergies, and stomach and liver cancer.
Where is Radon Found?
Radon is found underground. It can migrate
from one place to another by way of underground rivers and ground faults
(i.e., fissures. ) Upstate New York is located in an earthquake
zone which has many fault lines. This means that there are many routes
by which radon can travel.
Note: Since radon travels
underground, it's possible for one house to have high radon levels
while neighboring houses can have low levels.
How Often Should I Test?
Geology is dynamic; the earth is
subject to constant movement and underground change. Hence, radon
levels can very dramatically over time. Inside a home, radon levels can
vary with respect to changes in the season. For example, in the winter,
when doors and windows tend to be closed, radon builds up and levels are
higher. To be safe, the United States Environmental Protection Agency
(EPA) recommends periodic radon testing. Some authorities advise either
annual radon testing or the use of continuous in-home radon monitors.
How Long Does a Test Take?
Typically, a radon test takes 48 hours.
Specially calibrated instruments designed to measure the concentration of
radon are positioned in the basement and other levels of the home.
