Special properties

The legal regulations on radon protection also affect all special buildings such as listed buildings, historic buildings, barracks and other military properties.

In radon precautionary areas, special protection requirements have applied since 2021: If a reference value of 300 becquerels per cubic meter of indoor air is exceeded, measures to reduce the concentration must be initiated (§ 128 StrlSchG).

Leading experts from the WHO, the Federal Office for Radiation Protection and the Federal Environment Agency even advocate a reference value of only 100 becquerels per cubic meter.


We specialize in taking special safety aspects into account, even in military facilities or clinics.

Listed buildings are carefully renovated using special techniques in accordance with current regulations and adapted to the circumstances using the appropriate renovation method.
