Various kinds of tube shields have been recommended for thera-peutic work. The protection idea is a good one, but the tube shields,except glass, seem to shorten the life of the tube by carrying a partof the current around the tube, making it necessary to use strongercurrents and thereby increasing the liability to puncture. Theauthor has discarded tube shields, except those of glass. ACCESSORY X-RAY APPARATUS 109 r. LEADED GLASS TUBE SHIELD. The leaded, glass tube shield (Fig. 71) is the only shield thatdoes not seem to shorten the life of the tube. It protects both theoperator and the patient, and allows the tube to be seen at all tube shield is used withthe compression diaphragmshown in Fig. 69. Both thetube and shield should be thor-oughly wiped after each treat-ment to free them of the dustthat rapidly accumulates ontheir surface when in use. Where a great deal of skia-graphy work is done, the op-erator should stand behind aleaden screen (Fig. 72) andob- < .•■ ■%. ...) serve the tube through a leaded ^-~~»«^^=__i_-- -- Fig. 71.—Leaded glass tube shield. glass window m the top. It is the custom of some operatorsto wear leaden aprons, gloves, andglasses, but, if the screen is prop-erly used, it will afford all the pro-tection necessary. While on the subject of protec-
