The Silent Killer
Its interesting when you mention radon to many people you
don’t get much of a reaction. Many don’t even know what it is and those who do
don’t seem too concerned about it. The second you mention lung cancer it seems
to trigger alarms and immediately you have people’s attention. To what can we
attribute this passive attitude towards such a lethal resident in many of our homes?
Could it be that people just aren't properly informed or do they not see the importance?
What is Radon?
Radon is a radioactive gas that comes from the natural
breakdown of uranium in the soil. What makes it difficult to detect and
probably what may contribute to its lack of awareness is the fact that it is
completely undetectable by the human senses. It is a completely colourless,
odourless, and tasteless gas and is an intermediate product in the radioactive decay of
thorium and uranium to lead [1].
Why should You Care?
Though radon is gaseous, its decay products at times form
solids which are able to deposit themselves on surfaces as well as on dust
particles within the home. As these particles circulate in the air throughout
the house, they are inhaled and are able to enter into the lungs where they
remain. When in the lungs their radioactive nature contributes drastically to
the increased risk of developing lung cancer [2].

Radon can enter
your home any place where the house touches the soil and there is an opening. Possible entry points into your
home include: cracks in foundation walls and floor slabs, construction joints, gaps
around service pipes, support posts, window casements, floor drains, sumps or
cavities inside walls, dirt floors. The
amount of radon in your home will depend on many factors; the
amount of uranium in the soil, the number of entry points into your home, how
well your home is ventilated [2].
Radon testing
Radon is typically found in all provinces and territories in Canada, but concentrations vary depending on uranium levels found in the soil. Though it is expected that the majority of homes have some radon, only those whose levels surpass the recommended exposure amount require testing (200 Bq/m3). The only way to know the levels of radon in your home is with the use of an approved detector [3].

Radon test kits can be purchased over the phone, on the internet or from home improvement retailers. The kits include instructions on how to set up the test as well as how to send in results for analysis. To test your home for radon typically costs between $25 - $75, which to many would be a minor investment to provide peace of mind.
The the even that high radon levels are detected in your home, solutions are most not overly expensive and can
be quickly fixed.

So... What’s stopping you?
In understanding the severity of the risks that radon
exposure poses to the Canadian population, what public health professional
would like to know is what would it take to get every person in the country to
agree to get their homes tested for radon. What are some of the barriers that
are stopping you from getting your home tested?
Please tell us how you feel about radon testing and what
would inspire you to get your home examined.
