Physics professor Richard Wolfson discusses his book “Nuclear Choices for the 21st Century,” which explains, clearly and accessibly, the basics of nuclear technology and describes the controversies surrounding its use. The book begins with scientific issues, covering the nature of the atom and its nucleus, nuclear radiation, and nuclear energy. It discusses nuclear power, the operation of nuclear power plants, nuclear accidents, nuclear waste, alternatives to nuclear energy, and considers nuclear weapons: strategies for use and non-use, controlling the spread of these weapons to other countries and terrorist groups, and the prevention of nuclear war. “Nuclear Choices for the Twenty-First Century” offers readers an authoritative and unbiased guide to difficult questions.
