Zapped: From Infrared to X-rays, the Curious History of Invisible Light

Zapped explores the history and science of invisible radiation—infrared, microwaves, ultraviolet, X-rays, gamma rays, radio waves, and other forms of light we cannot see. These energies surround us constantly, emitted by electronic devices, the sun, cell towers, microwave ovens, CT scans, mammogram machines, nuclear power plants, and deep space. While excessive exposure is harmful, radiation is essential to life. Berman traces these discoveries from their origins in the 19th century to their central role in modern life. The book examines both the health costs and benefits of radiation exposure and explores the consequences of newer technologies. Written in an accessible, conversational style, the book combines historical narrative with scientific explanation and practical facts about the radiation that passes through our bodies every second.
