Paperback. Zustand: New. Print on Demand. This book delves into the transparency of various window materials, with a particular focus on the ability of these materials to transmit the ultraviolet rays of sunlight. The author examines the historical context of the discovery that common window glass blocks these rays, which are essential for preventing rickets. The book explores the development of new window glasses designed to transmit these vital rays, such as Helioglass and Vitaglass, and their subsequent solarization and decrease in transmission over time. The author also discusses the impact of solarization on the transmission of ultraviolet rays through these glasses and provides data on the transmission of various glasses before and after exposure to sunlight and artificial light sources. Through these investigations, the author sheds light on the complex interactions between sunlight, window materials, and human health, highlighting the importance of understanding the properties of these materials in order to optimize their use for therapeutic purposes.
