Overview
The author takes the novel approach of introducing the whole range of energies possessed by particles and electromagnetic waves at the beginning of the text, thus integrating coverage of ionizing and nonionizing radiation rather than considering them as two separate disciplines. He goes on to cover the entire spectrum of radiation sources, including radionuclides, x-ray machines, accelerators, nuclear reactors, power lines, microwave towers, and cellular phones.
With its expanded coverage, including a broader focus on public health issues, this new volume will serve as an important training and reference resource, not only for research scientists, physicians, and engineers, but for regulatory officials, attorneys, engineers, and environmental health and safety professionals. The breadth of citations alone makes this resource invaluable.
