This book examines the effects of nuclear explosions, both immediate and long-term, caused by the blast and radiation. It begins by describing nuclear explosions, and then it explains their effects, such as air blast phenomena, shock effects, effects of thermal, initial, and residual radiation and fallout, radio, radar, and biological effects, and electromagnetic pulses. The work is designed for both technical and non-technical readers. The first part of each chapter gives an easily understood presentation of the subject, whereas the latter part builds on that information, using greater detail and scientific and technical language. The book includes a glossary of terms and a guide to the concept of SI units.
