...infinitesimal sub-atomic particles. They are similar to radium rays and they work in exactly the same way to destroy living cells. They are created when a powerful electric current-i.e., a stream of electrons -jumps through a vacuum tube and hits a "target,", usually a piece of tungsten. The electrons batter from the tungsten a secondary stream of chargeless particles, X-rays, whose wave lengths are thousands of times shorter than those of ultraviolet light and almost as short as those of radium's gamma rays. The shorter waves are the farther they penetrate into matter before...
