The next step in combating the radon was additional slot vents and an increase in the supply of air. With 2 slot vents, the value dropped to just below 400Bq.
Not good enough.
After much googling, I ended up with the ventilation unit VL-100 from Mitsubishi. This was installed yesterday and is now running on low speed since the high-speed mode was too loud.

264Bq. Now we are really close to 200.

VL-100 requires 2 holes. Of course, there's rebar where you're drilling.
Hello.
Yesterday, we got the result from our long-term measurement after installing VL-100.
Somewhat disappointing at 380Bq.
I have still measured for at least a week with my own radon meter and got levels below the recommended 200.
Unfortunately, I see this as proof that our tenant still chooses to turn off the ventilator during periods.
So... Radon wallpaper did not work for me, and now not the ventilator either, which likely is due to our tenant rather than the product, which was relatively easy to install and works well.
I would definitely choose this solution if I had a basement or part of the house that needed a little extra air circulation.
The ventilator is incredibly simple and works, but not if you turn it off, unfortunately.
The next step will be a complete FTX. Damn, that's expensive!

But if the ventilator has been turned off, you need to take a new measurement with it turned on.
The daughter recently got new vents throughout the apartment, a slightly stronger draft in the fan in the kitchen and bathroom (the bathroom door gets sucked in), and a subsequent radon measurement. They were then instructed that they absolutely must not touch the vents until the measurement is complete, so it shows correctly. If they then choose to close them after the measurement is finished, it is their own responsibility, the BRF has fulfilled its part in the whole process if the measurement is approved with open vents.

But this is part of the problem. Everyone promises to keep the vents open, but they are closed the moment I leave the apartment. And since the OVK is then my responsibility, it becomes my fault as well when the values exceed 200.
So. The solution is still to install something that is harder to manipulate than simple slot vents.
