DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT Referring initially to FIGS. 1 and 2 of the drawing; a hood comprises the lead impregnated material of the hood and thyroid shielding device. This hood includes a usual eye, nose and neck opening. This facilitates for oral x-rays, yet with the eye flaps, engages and can afford shielding to the eyes. FIG. 3 is a cut away drawing showing a number of flexible layers of lead impregnated material. These inner sheets comprise multiple layers of flexible lead sheeting, the number of sheets used being determined by the degree of protection desired. For example one flexible lead sheet of 0.015 mm thickness is equal to 0.01 mm thickness of pure lead. FIG. 4 thus if 0.05 mm of lead protection is required, five layers of the flexible lead sheet of the desired thickness are used in the hood. Layers 13 and 19 are washable vinyl or other suitable material. Layers 12 and 20 are binding tape of appropriate material. Layers 14, 15, 15, 17, 18 are layers of lead impregnated sheets, usually 0.015 mm thickness. FIG. 5 is side version of shielding hood with #11 mouth shielding device being held in place by Velcro S. A. #10 tabs holding #11 mouth guard in place for #10 Velcro. Layers 8 and 9 are Velcro S. A. closures bands to ensure rapid and easy attachable closure for the neck thyroid closure. Layers 4 and 5 eye closure are complementary closures of the lead impregnated shielding devices in place. Layers 6 and 7 are the mating closures for 4 and 5 also #10 for the mouth shielding device. METHOD OF CONSTRUCTION The preferred embodiment of the present invention consists of -0.25 or 0.5 mm lead equivalent material such as in Main U.S. Pat. No. 3,093,829 hood ban be made in several sizes to fit the wearer. The body of the hood consists of lead impregnated material pliant, flexible, multi-layer body of sheet material 0.3 mm or 0.5 mm lead equivalency bonded to a supporting sheet of thinner material. Sew hood center/front seam together with appropriate thread thickness stitching firmly through the several layers of the lead impregnated material. Stitch the crown section to the hood. All said sheets of the lead impregnated material should be permanently fastened together along their perimeter by suitable material extending around the perimeter of the edges of the hood and stitched in place. The outer sheet of material can be of vinyl or material suitable for sanitation. The eye windows are also stitched with appropriate and suitable binding. Pairs of complimentary adhering closure tabs are sewed or cemented to sides of the eye and mouth guard opening in a vertical band. The tabs are known and may be made of tape of the type manufactured by Velcro, S. A. of Switzerland. The closure tabs are on the center area of the eye openings. The mating tabs are shown attached to the end of the eye openings, thus the protective shielding eye and material guards can be placed across the eye attached with Velcro S. A. with the shielding guard held in place over the eye. In like manner, the mouth shielding guard can be held in place by horizontally attaching the mouth guard to the hood using Velcro S. A. closure tabs to allow closure if the wearer desires. The thyroid section of the hood is also closed and secured by Velcro S. A. closure tabs at the chin and neck section of the hood. While the device herein described constitutes a preferred embodiment of the invention, it is to be understood that the invention is not limited to this precise form of device and that changes may be made therein without departing from the scope of this invention which is defined in the appended claims.
