Abstract
A protective face mask to shield an x-ray technician or machine operator primarily from random secondary or scatter x-rays deflected toward his face, head and neck by the table, walls, equipment and other reflecting elements in an x-ray room, during the period of exposure while adjacent the object or person being exposed to the x-ray beam.
The face mask is formed of a lens portion supported in a plastic frame, upon the lower portion of which is removably attached a bib shield that in turn is removably attachable to an apron. The frame of the face mask, bib shield and apron are preferably lined with lead sheets to protect the neck, face, chest and body of the technician from the random secondary or scatter x-ray beams. The face mask and bib shield can be formed of a molded plastic material as a unitary device, the lens portion being attached to the frame therefor.
