IN spite of the differences of opinion regarding the relative value of high voltage and supervoltage roentgen rays, the trend in the radiation of malignant disease is toward the use of the shorter wave lengths. In most clinics where large amounts of radium are available, it has been the impression that telecurie therapy possesses advantages over the use of 200 kilovolt roentgen rays
