The house plans indicate that it is made of concrete hollow blocks. House 1979.
I am checking where the radon is coming from. It could be from the ground, but inside a closet, there is this wall and the levels are at 800 if you close the door.
It could also be from the ground since there is only a slab under the closet.

My meter RadonEye doesn't give higher readings so far, so I don't think it's blue concrete.
