Materials and methods of manufacturing radiation shielded enclosures is presented that may replace the use of lead, granite and other undesirable materials and manufacturing methods. The present invention provides a high-density radiation shielding enclosure manufactured using a fiberglass lay-up or pressure spaying process and tungsten powder. The method of manufacture may include applying a tungsten powder in an epoxy, caulking, sealant, adhesive or elastomeric compound to the radiation shielding enclosure in order to seal any cracks, holes, joints or other radiation leaks.
