Radon Gas
There are a few changes coming in the next building revision. One of the changes will affect how some renovations are completed and all new homes are built.
Its all about radon gas.
You may not know you have a radon gas problem unless you test for it. Radon is an odourless, radio active, invisible, slightly heavier than air gas. It is naturally occurring in the ground. It is more pronounced in rock and rocky soils.
Health Canada has a great deal of information about what are safe levels of radon, how to test for it, and the health affects of radon gas.
The only way to confirm you have it is to test for it. Health Canada has approved various pieces of equipment for this purpose. The important part is, the test must run for a period of time. This is because you could have a low amount of radon one day and the next day it could be very high. Therefore to get a true understanding of how much you have is to account for these variations.
Radon can be removed from your home fairly easily. All you have to do create a negative pressure under the basement concrete slab. Unfortunately, this can get expensive to do after the slab is in place and no under slab piping is in place. Usually what is done after the fact; is to drill a hole in the slab, install a fan and ducts, seal all the slab to wall joints and floor cracks, and then hook up the equipment and ducts. The simple addition of pipe under the slab and ensuring that enough clear stone is under the slab makes the creation of negative pressure much easier and more effective.
Because of the growing awareness of radon and how common it is, the building code is changing. These changes are inexpensive to put in place as you build, but can be very expensive if they are after the fact installs. Once these parts are in place; at any time in the future, the remaining fan and hook ups can be installed to ensure radon is kept to a safe level.
This code change is cost effective and was brought into place with all of the involved parties coming to a solution that works – for all.
