During the last 30 years, there has been a remarkable devel opment and increase in the number of processes and devices that utilize or emit non-ionizing radiant energies such as micro waves, a form of electromagnetic wave energy and ultrasound representative of mechanical vibration. These energies are used in all sectors of our society for military, industrial, telecommunications, medical, and consumer applications. More recently, the use of ultrasound in biology and medicine has been considerably expanded. These increases in sources of non ionizing radiant energy have resulted in growing interest on the part of government regulatory agencies, industrial and mili tary physicians, research workers, clinicians, and even environ mentalists. Although there is information on biologic effects and potential hazards to man from exposure to microwaves or ultrasound, considerable confusion and misinformation has permeated not only the public press but also some scientific and technical publications. Interest in the biologic effects of high frequency currents developed in the beginning of the present century. This was followed by the introduction of "u1trashortwave" therapy. During the latter part of World War II, the U. S. military services became interested in the possible hazards to personnel working around microwave sources, and the Office of Naval Research of the U. S. Navy began to sponsor research on the biologic effects of microwaves in 1948. In 1956, the U. S.

An Introduction to Non-Ionizing Radiation provides a comprehensive understanding of non-ionizing radiation (NIR), exploring its uses and potential risks. The information is presented in a simple and concise way to facilitate easy understanding of relevant concepts and applications. Chapters provide a summary and include relevant equations that explain NIR physics. Other features of the book include colorful illustrations and detailed reference lists. With a focus on safety and protection, the book also explains how to mitigate the adverse effects of non-ionizing radiation with the help of ANSI guidelines and regulations. An Introduction to Non-Ionizing Radiation comprises twelve chapters, each explaining various aspects of non-ionizing radiation, including: Fundamental concepts of non-ionizing radiation including types and sources Interaction with matter Electromagnetic fields The electromagnetic wave spectrum (UV, visible light, IR waves, microwaves and radio waves) Lasers Acoustic waves and ultrasound Regulations for non-ionizing radiation. Risk management of non-ionizing radiation The book is intended as a primer on non-ionizing radiation for a broad range of scholars and professionals in physics, engineering and clinical medicine.

Over the past several decades, public concern over exposure to ionizing radiation has increased. This concern has manifested itself in different ways depending on the perception of risk to different individuals and different groups and the circumstances of their exposure. One such group are those U.S. servicemen (the "Atomic Veterans" who participated in the atmospheric testing of nuclear weapons at the Nevada Test Site or in the Pacific Proving Grounds, who served with occupation forces in or near Hiroshima and Nagasaki, or who were prisoners of war in or near those cities at the time of, or shortly after, the atomic bombings. This book addresses the feasibility of conducting an epidemiologic study to determine if there is an increased risk of adverse reproductive outcomes in the spouses, children, and grandchildren of the Atomic Veterans.
