them? We shall protect ourselves by never expos-ing any part of our bodies to the direct or primary X-rays, and our pa-tients by exposing them as short a time as possible. How can we do radiographic work without exposing ourselves tothe X-rays? Sheet lead one-eighth inch thick is opaTjue to very penetrating X-rays.Lead glass—a transparent glass containing a great deal of lead silicate—though it would need to be about two inches thick to totally obstruct verypenetrating X-rays, nevertheless offers considerable, and perhaps suf-ficient, protection in the thickness of one-quarter inch. The writer was informed that linoleum is opaque to the X-rays. Totest the verity of this information Figs. 311, 312 and 313 were made. A,. study of the illustrations will show that, compared to lead or lead glass,linoleum offers very little resistance to the rays; compared to wood, theIesistance is much greater. White linoleum offers more resistance thanred, green or blue. THE DANGERS OE THE X-RAY 279
