Method for shielding against dangerous microwave radiation during drying of a surface of a water damaged building part by one or more mobile unit(s) emitting microwave radiation against the surface that is being dried, which method comprises installing a temporary, easily applied and removed, metal foil as a partially covering of the surface to be dried so that microwave radiation can be reflected back onto the surface to be dried while allowing evaporated water to escape from the surface at uncovered areas. The foil is applied to cause the radiation to pass through at least 50 cm of the building material to utilize the inherent quenching effect of the building material to help dry the water damaged building part surface. Preferably, the foil is an aluminum foil and the building part is a ceiling, floor, or a wall of a building, and the foil is applied to surround the building part except in the area(s) of the mobile unit(s).
