radon gas problems with HRV systems

    Hi, I am about to start building my house and am looking into a HRV system and have been told by two people of problems with radon gas in the house. Apparently the pull of air from the house has caused seepage of radon into the house ( house is in a radon area ) even thou there was a radon filter barrier. could this be down to incorrectly fitting the barrier. Any advice would be welcome.

    The HRV system will bring in fresh air from outside and should be balanced - there won't be a pull of air from the house as such. If anything there will be a slight overpressure in the house and the constant exchange of air will get rid of any radon. If the radon barrier is fitted correctly then there won't be any seepage anyway.

    My opinion, FWIW, is that the Radon scare is a load of cobblers. The risk of cancer seems to be about the same as eating a well-done chop off a barbecue.

    If the radon barrier and associated sump/pipe are fitted correctly then there is no reason why the gas would be inside the house.

    Thats what i was thinking. The person who told me about the radon levels does the testing for it. He is also building his own house at the moment and not putting in a HRV system because of it.

    Ventilation and air movement will remove radon therefore removing any danger. HRV should has a positive affect on a house.

    Radon is a gas that is heavier than air, so it lingers in rooms in houses affect by radon.

    Smokers increase their risk of lung cancer by 25 times if they live in a radon exposed house.
