Radio-Therapy: Its Scientific Basis and its Teaching 1

    Article metrics


    THE recent discovery that X-rays and y rays can be defracted into spectra by the natural grating contained in the orderly structure of crystals, sets at rest the question as to the nature of these radiations. They are of the same nature as light-waves, but of very much higher frequency—from 10,000 to 100,000 times as high.
