Most people know that the sun’s rays have radiation and it can damage
both the skin and eyes. However, many do not realize that the earth itself also
gives off radiation. This radiation can seep into the house and become an air
hazard in your home. This type of radiation is known as radon gas.
Radon gas comes from the breakdown over time of uranium in the rocks
and soil around the house. Radon is found all through the environment. Yet,
when it is concentrated in high levels in the air inside a house or building,
it can cause cancer. Specifically, radon gas is the second leading cause of
lung cancer for smokers. It also is the top cause of lung cancer for
non-smokers. Overall, radon gas kills about 21,000 people per year via lung
cancer. This is even more than drunken driving deaths.
A big problem with radon is that it is invisible and cannot be
smelled. It can show up in any type of house — old or new — and it can appear
in houses with a basement or a slab foundation.
The EPA estimates that one out of 15 homes in the U.S. have high radon
levels, or about 8 million houses.
Radon gas is usually one of the leading environmental concerns that
the federal government deals with, and is the top environmental reason for
cancer. This is the reason that the U.S. Surgeon General recommends radon
testing for all homes. Radon gas is indeed
dangerous, and you should follow the advice of the surgeon general.
The EPA has established an action level, at which you should deal with
the radon level in your house. The action level is 4 picoCuries per liter of
air. However, know that amounts lower than this may not be safe, either. The
WHO states that levels higher than 2.7 picoCuries is dangerous.
