I read http://www.radonit.se/publikationer/effektradon.pdf and got interested in the Kohlström method. But I don't understand what they mean, are there pictures of it? What kind of corrugated cardboard sheets and how do you ventilate it? I've extracted a section from the PDF file below
radon in building materials Kohlström method The Kohlström method aims to prevent the transfer of radon from blue concrete walls to indoor air. This is done by ventilated air spaces along the walls created by mounting corrugated cardboard sheets directly against the wall surface. The radon level decreases by 65 percent.
Thankful for a response

Swindling?
Normally, you just increase the ventilation.
What do you have today?

Suspect that it may be difficult to ventilate through such small channels without them getting clogged with dust. Once they become tight, it must be very difficult to clean them. The principle itself is probably fine compared to a Platon mat with a fan or ventilated strips, but then it's a matter of significantly larger dimensions.
