Protective glasses against non-ionising radiation - has absorbing and reflective windows sealed at borders by flexible material

摘要

The protective glasses against non-ionising radiation, i.e. v.h.f. electrical radiation with wavelengths in the cm range, consists of two caps coupled together with windows of see-through material. The border(2) of each cap with its own window(1) is formed from flexible, elastic beading. The latter is made of material that is strongly absorbent for the non-ionising radiation. The beading can be hollow or enclose hollow chambers. The windows(1) can be transparent yet absorb and reflect the non-ionising radiation. They can be built up from several layers. The material used can be of plastics containing metal filings.
