The author of this monograph has attempted, and with success, to give a comprehensive review of the extensive literature on this subject. A chapter on the physics of radiant energy characterizes sunlight radiation at various latitudes, altitudes, seasons and hours of the day, compares the radiation from various commonly used artificial sources with that from sunlight, and discusses the modern tendency to use substitutes for ordinary window glass which are more transparent to the ultraviolet rays.
The book includes chapters on the effects of radiant energy on the skin, wounds and some cutaneous diseases, the eye, the blood and circulatory system, metabolism, the body temperature, respiration and reactions of the blood, photodynamic sensitization, tuberculosis and bacteria, toxins, antitoxins, proteins and ferments. The chapters on metabolism pay particular attention to the effect on calcium and phosphorus metabolism, rickets, tetany and growth and to the therapeutic value of various irradiated substances.
