What you can do to immediately reduce the radon level is to ventilate more.
Measuring the radiation in homes is done during the cold period of the year when you don't ventilate. You buy a "puck" from an analysis company, and the puck should be placed according to certain guidelines and remain still for a certain number of weeks, after which you send the "puck" back to the analysis company.
Not all blåbetong contains radon.

Thank you. I spoke with the association's trustee and we will conduct a radon measurement now in October.BirgitS said:
October feels far away, and I'm too worried to live there with children until October + measurement.
In another thread, you wrote, "Load-bearing walls are usually not made of light concrete, which blåbetong is, but there may be exceptions."
When we bought the apartment, I was told that interior walls are usually not made of blåbetong. But now that we tore down the gypsum wall, it really looks like blåbetong, airy and hard to determine the color, but it looks blue in the picture.
Inner walls can definitely be made of blåbetong. They exist here. We also lived in a place with a small child for two years where there was blåbetong. There are plenty of people who spent their entire childhood in the 50s, 60s, and 70s in houses with blåbetong and have not encountered any problems because of it.
In these new pictures, I think the only thing that looks like blåbetong is in the last image where various loose pieces and small remnants on the wall appear to be such.
In your first image in the thread, it also just looks like there are minor remnants of blåbetong on top of a wall made of regular concrete.
So, it really doesn't seem like there is anything to worry about. It's much more dangerous to smoke or spend a lot of time near heavily trafficked roads than to live with a bit of blåbetong. It’s also dangerous to go around worrying.

Exactly, looking at the overall picture that the carpenters have sent, it looks like there is blåbetong outside of regular concrete.
Haha, yes, all these dangers around us. What worries me is how much blå betong is actually in the apartment and if it can cause harm. But thanks for all the information.

According to the pictures, it seems that there's just a tiny bit of blåbetong left and the carpenters are probably not finished yet since the surface is particularly uneven.
A smaller part looks like Blå-Lättbetong, most of the rest looks like plaster, etc. You have to measure to be sure. And yes, Blåbetong has been used for load-bearing walls, if nothing else as insulation outside, for example, concrete cinder blocks or similar.
However, I DON'T think there is any reason for concern! Wait for the association's measurement and sleep soundly in the meantime!
In the summer, you ventilate so much that the levels are low, and Radon from building materials alone usually doesn't give astronomical values anyway. The big problems mainly come from ground radon.
