Microwave radiation blocker - an invention fit to any house owning a microwave. Microwave radiation blocker is made of metals alloys that block RF radiation (the one discharged while using the microwave) and thus keep us safe when we use it. The microwave is made out of 4 sides, three of them are metal and the forth is of plastic/ glass that does not block the radiation. This side is “the microwave” door. Microwave radiation blocker is attached with magnetic stripes onto the microwave door so we can pull and type it any given moment. It is used as the four sides that blocks the microwave radiation and keeps it inside the microwave itself. The microwave radiation blocker is an external product and its sole purpose is to be radiation blocker for internal use, or any other use.
