ABSTRACT:
In combination with an electric apparatus emitting electromagnetic radiation, an arrangement for reducing the radiation hazards on an operator in front of the apparatus is provided, the arrangement comprising at least three magnetic devices approximately located at the apices of a triangle in front of the apparatus, each magnetic device including a closed housing made of a nonmagnetic material, a permanetn magnet located within the housing for producing a magnetic flux, and a bar of non-magnetic material located within the housing in a defined spaced-apart relationship such that the bar of non-magnetic material is placed in the effective flux area of the permanent magnet, the magnetic devices being positioned in front of the apparatus such that each permanent magnet has its north pole opposed to the south pole of the other magnets and such that each bar of non-magnetic material is situated behind the permanent magnet associated thereto.
