ABSTRACT:
An article for protection of gonadal areas, of a human body, against radiation, is disclosed. The article comprises (a) an elongated sheet of fabric material with a first end and a second end and having a width of 10-30 cm; (b) at least two complementary fastener means; and (c) a layer of flexible radiation protection material with a width of 10-30 cm and extending longitudinally from the second end towards the first end. One of the fastener means is located juxtaposed to the first end and the other is spaced apart from the first end, and the sheet of fabric is adapted to fold back on itself and be held in the folded position by the fastener means, thereby forming means to secure the article around the waist of a human body. The layer of radiation protective material has energy attenuation properties at least equivalent to 0.1 mm of lead at 100 keV, and is of a length such that when the fold is located at waist level on a human body the layer extends from above to below the gonadal area. The sheet of fabric material and the layer of flexible radiation protection material are attached circumferentially on three sides so as to form a pouch. The article is intended for use in the protection of the gonadal regions of the human body e.g. of operators of x-ray or other radiation emitting sources.
