Abstract
An electromagnetically shielded cabin is disclosed which utilizes a novel sealing system enabling reduced maintenance expenditures for maintaining necessary electrical contract, and thus the necessary shield attenuation values, when cabin parts are made of aluminum. The contact surfaces forming part of the novel sealing system are coated with tin which enable the reduced maintenance expenditures and achieve excellent shield attenuation values.
