RADIATION LIMITING OPENING FOR A STRUCTURE

摘要

A radiation limiting opening for a structure includes a door with a gasket which seals against a door frame about the opening. Spaced apart channels in the door frame define a strike plate therebetween. A film made of a material galvanically compatible with the gasket to prevent corrosion is in intimate contact with the strike plate by a seal. This seal lodges an edge of the film in each channel to create a tortuous path for radiation.
