Blue concrete, is it worth the trouble to remove?

[mexximatte]

How have you handled walls made of blåbetong? Kept them or removed them? We've exposed a wall that had wooden paneling against it. The radon level is slightly high but below the limit, and we would like to reduce it a little further. Additionally, the wall is for a room that will likely be used as a bedroom for one of the children. Does it cost extra to get rid of blåbetong?

It would be interesting to hear what others have done.

How have you dealt with walls made of blåbetong? Kept them or demolished them? We have exposed a wall that had wooden paneling on it. The radon level is a bit high but below the threshold value, we'd like to reduce it a bit more. Additionally, the wall is in a room that will likely be used as a bedroom for one of the children. Does it cost extra to dispose of blåbetong?

Kept it and spent the money on better ventilation. Alternatively, changed residence.

If there is blåbetong in one wall, it's likely in all (similar) walls in the house. No point tearing down and rebuilding a new wall if the other 3 walls in the room still contain blåbetong.
If you don't want it, you have to move.
If you want to reduce radon levels, ventilation is the way to go.
There are limits for Radon, but isn't it the case that the only scientifically found link is that Radon is harmful (increased cancer risk) if you smoke? I don't think they've managed to link just Radon exposure to increased cancer.

Thanks for the response. The other three walls in a 30 sqm room are made of hollow concrete block. According to the drawings, two walls are "light concrete" and the others are hollow concrete block. So the load-bearing walls and exterior walls are not blue concrete. The upper floor has a timber frame.

Did you know that radon comes from blue concrete and not from the ground?
Not all blue concrete releases radon.
