Radon is a colourless, odourless, tasteless radioactive gas. It is formed by the breakdown of uranium in the soil. It enters the home at any opening where the building meets the soil such as exposed rock or soil, foundation cracks, floor drains, sump pumps etc. If Radon accumulates to high levels it can become a health hazard. Radon is the leading cause of lung cancer in non-smokers and the second leading cause of cancer in individuals who have smoked. It is a serious health issue that should not be ignored.
Every home will have some level of Radon, it is important to know your level and reduce it as much as possible. Health Canada recommends that you have a mitigation system installed if your levels reach 200 Bq/m3, however the acceptable level for the World Health Organization is 100.
We recommend the long term test that is available through the SK lung Association. You will register your test with your email and then keep it in your home for 90 days. After the 90 days are up, you will send it in to be read, and you will receive an email back with your results. You can order your Radon test kit here. While any time is a good time to test for Radon, it is recommended to test during winter months as that is when the home is the most closed up and will give you a truer indication of your radon exposure.
We use a Sub Slab Depressurization method, or SSD. SSD is recognized as the best available technology for reducing Radon levels in homes. This system uses a specialized Radon fan to extract Radon from beneath the basement slab, which is then vented to the outside. The fan is very quiet, runs continuously and should never be unplugged. As part of the mitigation, all other areas that could leak Radon into the home are sealed, such as sump pit covers, cracks, unsealed drains, etc.
A HEALTHY HOME IS A MITIGATED HOME!
A typical Radon mitigation system includes schedule 40 PVC piping from the suction pit to the specialized radon fan and from the fan to the exterior venting. A critter guard is included so no unexpected visitors can enter from the outside.
