Asbestos in the flooring of a house from 1972?

And has your father become ill because of it?

Not so far, luckily, and I sincerely hope it stays that way. But even if he does become ill, that does not at all mean that someone exposed to a ten-thousandth of that burden will also get sick.

When assessing occupational illness cases, they don't call it asbestos years for nothing — full years during which an employee was exposed to the material every day.
Of course, the famous one fiber can be enough. But in the vast, vast majority of cases, it takes massively more exposure.
Try to relax a bit. Take the risks seriously, but also try to see them realistically.

Only then you quickly end up paying 10,000 euros for removal and laying a new floor, and I think that's quite steep. I didn't expect it to be so expensive..

But the company's offer was only 4,000 euros, right? Laying a new cheap floor in the basement (if even necessary, many are fine with just the screed) is a great thing to do yourself. And 36m2 doesn't cost much material.

Another question. In our other basement room, another floor has been laid over the KMF-contaminated floor. I cannot say whether this one is contaminated. It lies loosely on the KMF floor without adhesive, I can describe it like that. Then no danger can come from this new floor as long as I don't go at it with a knife or something, right?

Then this new floor can’t pose any danger as long as I don’t go near it with a knife or something, right?

And what about carcinogenic fumes? Who knows what kind of synthetic material it is and what was used in processing. Get it out immediately!!!

Here is the lab report. Can someone assess this?

No asbestos present. KMF present - WHO fibers also. How many and whether they are released/will be released and are in the air is not stated. Therefore, no risk assessment is possible.
