    During the winter we undertook a radon measurement of our house. We have two house 10m apart (one a kind of guest or retirement house the other is the main house.


    Main house: 107 Bq/l
    Cottage: 43 Bq/l

    Here i Norway they said it should be under 100 Bq/l and for communal buildings and rented accommodation under 200 Bq/l

    Whenever I try and google “radon” I just get bombarded by companies saying they will sort it out for a big price. Our house is old traditional wood log cabin sitting directly on a concrete wall. Natural ventilation throughout. In the creep celler there is soil (where I imagine the radon is coming from). My thoughts was to install myself a ventilation system in the floor of the lower rooms with a radon sucker in the celler and then a chimney through the roof to cast out the radon. Or just get ventilation in the creep celler (as its quite damp anyway) and hope that reduces the levels to a more acceptable level.

    Question: Crazy idea? and does anyone have any links to do-it-your selv radon ventilation systems.

    Reality check: Difficult to get a straight answer for what I can see the difference between say 43 and say 107 Bq/l in reference to long cancer is no very much. Anyway the misses saw the readings and now something has to be done :)
    Yes, start off with improving the ventilation in the crawl space, leaving one of the vent holes capable of accepting a fan if need be.

    Have you looked at the UKRadon site?
