For us, we decided that even if the risks to Radon were not conclusive, there didn't seem to be any downside (other than cost obviously) to removing the radon so out it went.

What Radon reduction system did you use?

Thanks for the replies so far. May order the long term test kit. The meter seems nice though as you could pass it onto friends etc. In my research a place called radon west has a 'real estate test', which would make things more official when buying / selling property. But they are $350.

The home depot ones are not recommended. Their accuracy is questionable and even if it is somewhat accurate it's a short term test. Short term tests tell you what your radon levels are over a three day period, day four can be completely different.
Radon levels in your home change about as often as the weather does. You and your neighbor can have completely different levels.

Current Canadian Building codes require a Radon depressurization system installed under slabs in new homes.

Had radon west install a sub slab depressurization system (it's essentially a hole in the floor with piping to the outside, and a fan designed to run continuously.

Just to clarify, the current codes require a 'rough in'...which is not exactly a depressurization system. (Makes install of a system easier essentially.)

100% correct. I was going to edit my post, but let it go.

LChoy, could you ask your wife if periodically turning on the washroom fan is sufficient? I'm thinking about hooking it up to a clock so it turns on every night from 2:00 am - 5:00 am.

Will do

I had my home done with the long term Radon West test. main floor over last winter (ie" most sealed up time of year) was 144 Bq/m3 - Well inside the acceptable range.

From wife (Ontario Lung Assc Radon Program):
Quote:
Basically more ventilation means lower levels since it dilutes the radon level inside. So definitely helps to have the fan running but it will just go back up when its turned off.
That's why the most effective way to lower radon levels is to install a radon mitigation system that is made up of a fan inside a pipe that runs 24/7 to keep air moving and keep levels low
|
Hope that helps
LChoy (+ Mrs LChoy)

Sorry to bombard with questions, but I'd love to know more about your experience with the install:
How destructive/disruptive was it to do? Was there much ripping up the floor & walls? How long did it take to install?

Since 2012 in BC
As noted by Ace above, it is the rough in of the system that is required.

So we live in an older house built on top of a concrete slab, no basement or crawl space. Should we be concerned at all about this? We live in the Lynnwood area, up on the ridge from Ogden.

Ask for Colin and Radon West. The guy is meticulous and clean. The install took about 6 hours, and the main hole was cored through my existing sump pump location and then I bought a new sump pump cover (with a pre-formed access hole for the piping) from them (everything looks neat and tidy). For testing they drilled 1 hole 1/2" diameter at most - under my stairs (but sometimes they like to do 3 or 4 holes depending on your house). He put some fill in the hole and you can't even really tell. If your basement is finished they can often pull up a bit of carpet and you don't even know they drilled a hole.
My understanding is since most newer houses have a good amount of gravel under them, these systems are incredibly effective with minimal effort.

In Alberta new homes that started construction after about Nov 2015 are subject to the rough in system.

I wonder if the lead and hydrocarbons in your soil protect you from radon?
