Abstract
A radiation containment apparatus comprising a source of radiation having an area from which radiation is emitted, and a vinyl polymer sheet generally arranged about the area from which radiation is emitted in a manner so as to receive the radiation. The source of radiation is a cathode ray tube. The vinyl polymer sheet is a clear sheet of polyvinyl chloride. An enclosure made up of polyvinyl chloride sheets generally surround the source of radiation. A plurality of fasteners are arranged about the periphery of the cathode ray tube so as to receive the polyvinyl chloride sheet. The polyvinyl chloride sheet also includes notches about the outer edges for engaging the fasteners on the cathode ray tube.
