IN THE brief discussion that follows I propose to limit my remarks to the practice of using the ionizing radiation of radium in the nasopharynx and pharynx for the reduction of lymphoid tissue causing definite symptoms. The difficulties of the complete surgical removal of such tissue make such radiation not only the most convenient but the most efficient means of treatment.
Radium and its emanation, radon, have exactly the same characteristics in that they constantly emit three types of radiation: 1. Alpha rays, which are positively charged helium nuclei; since these cannot pass through the wall of the Monel metal capsule used in treatment, they require no further consideration. 2. Beta rays, comprising about 80 per cent of the radiation, which are negatively charged electrons of varying high speeds up to that of light; their chief characteristic is their comparatively mild ability to penetrate living tissue; it is
