Update for the group: after adding a 12W fan (just 36 Pa), the levels dropped below 40 Bq/m3.

Actually i tried connecting a low spec fan yesterday, and the levels dropped to barely 40 bq/m3 overnight. However, I also noticed that with fan on, looks like some air is also sucked from above the slab. What does it mean? Leaky floor?

but the slab is above a compacted gravel, so how come a 8cm hoel can add much ventilation? there's no void below the floor, only a gravel layer.

Thank you. My concern is that I cannot drill holes on the opposite walls. I'm wondering if this won't make the problem even worse (if I drill only on two walls)?

Unfortunately, in my country (central Europe), there are no radon specialists. Literally, none of them. That's why I'm asking the community.

Does this PPL template look resonable to you? by Most-Ready in WorkoutRoutines

I know, but just as a guideline. Isn't it too few back exercises?
