Measurements:

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 :)]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15727&Focus=268305#Comment_268305 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15727&Focus=268305#Comment_268305 Mon, 14 May 2018 16:01:27 +0100 Nick Parsons
Have you looked at the UKRadon site?

Safe levels are a myth, there are no safe levels and the longer you live with them the greater the danger of adverse impacts.

The advice seems to be sumps, ventilation and fans]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15727&Focus=269399#Comment_269399 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15727&Focus=269399#Comment_269399 Mon, 16 Jul 2018 11:18:15 +0100 bhommels I would think that, in addition to (forced) ventilation, a polythene would help. Better even would be a foil with metal flash on it, like crisps bags.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15727&Focus=269402#Comment_269402 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15727&Focus=269402#Comment_269402 Mon, 16 Jul 2018 16:41:25 +0100 tony http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15727&Focus=269405#Comment_269405 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15727&Focus=269405#Comment_269405 Mon, 16 Jul 2018 20:06:01 +0100 Fred56 I say this cautiously because I have lost faith in the BRE, too much market control and ideological bunker thinking.

A few years ago I was doing a job with ground gas and the geology required a raft foundation. In my investigation for solution I had a long talk with a Swedish architect who described a method of venting under a floor or a raft (he was selling passive raft systems). His basic plan was to allow external air feed into the chamber/void from the shady side of the building and vent to the sunny side with pipes rising above the eaves and windows. The idea being that a passive stack was created at the warmer side and air was drawn through. Simple, silent and uses no energy except incident solar. I am not sure much good it is the arctic circle and I have never tried it but I know the general principle works.I have passive stacks in two bathrooms as well as positive input in my bunglaow in radon suspect Cornwall.]]>
