Abstract
In one aspect, a protective face mask designed 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 or chamber, during the period of exposure while adjacent the object or person being exposed to the x-ray beam.
In another aspect, the face mask and chest shield device can be mounted on a patient'"'"'s shoulders in reverse attitude to protect the back of a patient'"'"'s head and neck from the x-ray beam while being exposed to such beam for chest or upper body portion study and examination.
The face mask is relatively or substantially transparent and contains lead in combination with a plastic ionomer or comonomer, which absorbs or resists penetration, to a degree, of the random deflected secondary or scatter x-rays or the x-ray beam through the mask. The face mask is removably attachable to the chest shield for facile application of the device to and support upon the shoulders of the technician or the patient.
