I have also dealt with this topic because my brother wants to buy a house and the high-voltage power line runs about 60 meters from the house.
There are no clear findings as to whether such a high-voltage power line emits magnetic fields that can cause health damage.
However, the minimum distance to a cable for high-voltage power lines should be at least 10 meters. But of course, that also depends on the person and whether they are sensitive. Also, that is just a story and whoever is anxious should refrain from buying.
