Hi!
I tore down the tiles in the kitchen and I notice that the concrete is blue-gray and I know that this usually means there's radon in it.
I can't find any information about working with blåbetong. For example, when replacing tiles, drilling into the wall, etc. where concrete dust/debris is flying around. Is it dangerous? Drilling is so common that everyone does it at some point. Replacing tiles is a bit more unusual, but when I removed the tiles, there was nothing between the tiles and the concrete wall besides tile adhesive and a layer of paint (over perhaps a thin layer of smeared gypsum, not gypsum board), so when I removed the tiles, everything came off with the tiles, leaving the concrete exposed.
Is it dangerous in any way? Anything I should consider?

No, blue concrete is not more dangerous to work with than other dusty materials. The radon is present whether you process the concrete or not. This is a significant difference from asbestos, which is another "dangerous" material. Asbestos is only dangerous when it is dusting.
Considering the unpleasant and unhealthy nature of concrete dust in the throat, nose, and lungs, it might be a good idea to wear a respirator when working with it, especially if you are going to process it a lot (like tearing down a wall or so). But as mentioned, not for the sake of radon.
