Radon is a radioactive gas that occurs naturally when the uranium in soil and rock breaks down.
It is invisible, odourless, and tasteless.
When radon is released from the ground into the outdoor air, it is diluted and not a concern.
In enclosed spaces like homes, however, it sometimes can accumulate to high levels, which can be a risk to the health of you and your family.
Exposure to high levels of radon in indoor air results in an increased risk of developing lung cancer.
The risk of cancer depends on the level of radon and how long a person is exposed to those levels.
There are two options for testing a house for radon: to purchase a do-it-yourself radon test kit or to hire a radon measurement professional.
If you choose to purchase a kit, you must follow the instructions closely on how to set up the test.
If you choose to hire a service provider to perform the radon test in your house, it is recommended you ensure they are certified and will conduct a long-term test for a minimum of three months.
Radon test kits may be purchased over the phone, on the Internet, or from home improvement retailers.
The kits include instructions on how to set up the test and to send it back to a lab for analysis once the testing period is over.
The cost of testing ranges from $25-$75.
