X-ray proof gloves. These gloves are usually made Tig. 320. of rubber impregnated with lead or some salt of lead. Protective gloves may be made by painting ordinary leather gloves with several coats of white lead. X-ray proof or opaque gloves, as they are called, are not really opaque to X-rays; they are, in fact, quite translucent to powerfully penetrating rays. Gloves should be used when the operator finds it necessary to holdthe film in the patients mouth himself. Seldom, very seldom indeed, is.
