Should You Test Your Home
for Radon? YES!
What is Radon?
It is a radioactive gas, formed by the breakdown of uranium,
a natural radioactive material found in soil, rock and groundwater. It is
colourless, odourless and tasteless. When radon is released from the ground
into your home through the basement, it is diluted and low in concentration but
some Alberta home have higher levels than recommended by the International
Commission on Radiation Protection.
Radon is the Leading Cause
of Lung Cancer in Non-Smokers in Canada!
The risk is high. Radon exposure is nearly everywhere in the
northwest corner of the continent. The scale of radon exposure in the Canadian
Prairies is the second highest on Earth. A recent University of Calgary study,
reported that one in eight Albertan homes tested over safe levels of radon gas.
Results may not be seen for years but the damage to your DNA is a real concern.
Exposure is estimated to be the cause of 16% of lung cancers.
Indoors - Radon can
be a Big Problem
When radon mixes with the air outside, it is not a problem:
the air outside dilutes the amount of radon. But when radon seeps into a
closed-in space like a house, it can be harmful. You and your family can
breathe in high levels of radon without knowing it. Every house in Alberta has
a yearly freeze-thaw action due to the water underground. This movement causes
continuous erosion. If your house is older there could be extensive gaps,
fissures and cracks and many other holes allowing the gas to seep in. Testing
should be done every five years or after major renovations or changes to the
HVAC system. Even if neighbouring homes test low for radon, yours could still
have high levels.
How Do You Test for
Radon?
If your house is newly built you have to wait until the
concrete cures. This takes 18 months. Then a proper radon test takes a minimum
of 90 days and should be done in the winter. According to the Canadian Lung
Association, web site, you should put the test device on the lowest level of your
house that you use regularly at least four hours a day. Make sure it won't get
knocked over. Then you mail the test device to the company’s laboratory according
to package instructions. The company will analyze the test device in their
laboratory and mail or email you the results.
What do I do if I
have high radon levels?
Health Canada radon guidelines say that no action is
required if radon is below 200 Bq/m3. However, even low levels of radon can be
harmful. It is better to try to lower your home's radon level as much as
possible. You need to repair your home if your home’s radon level is between
200 and 600 Bq/m3 within in the next two years and if over 600 Bq/m3 then you
should repair your home within one year. You may need to hire a contractor to figure
out where the radon is coming in so that you can make repairs to block the
radon.
Government Mandated -
Remediation.
The government has mandated that every home built since
November, 2015 should have a sub-slab depressurization rough-in installation
site. This allows for an effective form of radon reduction with reduced costs. Your
Real Estate agent can tell you if a home that you are interested in has a
rough-in depressurization site, has been recently tested, see the copy of the
recorded test result and tell you if the necessary remediation has been done to
make the home safe. If there is work that needs to be done to reduce radon, the
estimated cost is around $2,000 to $3,000 but much less if you have a sub-slab
rough-in.
Are Our Calgary
Schools Safe? – They are On-To-It
You may soon receive a notice that the CBE will be
conducting tests for radon gas in a number of schools across our system. Thankfully
they are being proactive about our children's safety.
