This is a positive and accessible account of the effect of radiation on life that brings good news for the future of mankind. For more than half a century the view that radiation represents an extreme hazard has been accepted. This book challenges that view by facing the question "How dangerous is ionising radiation?" Briefly the answer is that radiation is about a thousand times less hazardous than suggested by current safety standards. For many this will come as a surprise and then quickly raise a second question "Why are people so worried about radiation?" This is the out-of-date result of Cold War politics combined with a concern about radiation that was appropriate in an earlier age when the scientific understanding was limited. In the book these answers are explained in accessible language and related directly to modern scientific evidence and understanding, for instance the high levels of radiation used to the benefit of health in every major hospital. Four facts illustrate the need for a new understanding. 1. The radiation levels in the nuclear waste storage hall at Sellafield, UK are so low (1 micro-sievert per hour) that anyone would have to stay there for a million hours to receive the same dose that any patient on a course of radiotherapy treatment receives to their healthy tissue in a single day (1 sievert or gray). 2. The radiation dose experienced by the survivors of the Hiroshima and Nagasaki bombs caused 0.6% to die of radiation-induced cancer between 1950 and 2000, that is about 1/20 of the chance of dying of cancer anyway and less than the chance of being killed on US highways in that period. 3. The wildlife at Chernobyl today is reported to be thriving, despite being radioactive. 4. The mortality of UK radiation workers before age 85 from all cancers is 15-20% lower than comparable groups. The case for a complete change in attitude towards radiation safety is unrelated to the effects of climate change. But the realisation that radiation and nuclear energy are much safer than is usually supposed is of extreme importance to the current discussion of alternatives to fossil fuels and their relative costs.

In the United States there are several thousand devices containing high-activity radiation sources licensed for use in areas ranging from medical uses such as cancer therapy to safety uses such as testing of structures and industrial equipment. Those radiation sources are licensed by the U.S. Nuclear Regulatory Commission and state agencies. Concerns have been raised about the safety and security of the radiation sources, particularly amid fears that they could be used to create dirty bombs, or radiological dispersal device (RDD). In response to a request from Congress, the U.S. Nuclear Regulatory Commission asked the National Research Council to conduct a study to review the uses of high-risk radiation sources and the feasibility of replacing them with lower risk alternatives. The study concludes that the U.S. government should consider factors such as potential economic consequences of misuse of the radiation sources into its assessments of risk. Although the committee found that replacements of most sources are possible, it is not economically feasible in some cases. The committee recommends that the U.S. government take steps to in the near term to replace radioactive cesium chloride radiation sources, a potential "dirty bomb" ingredient used in some medical and research equipment, with lower-risk alternatives. The committee further recommends that longer term efforts be undertaken to replace other sources. The book presents a number of options for making those replacements.

This text treats the fundamentals of optical and infrared detection in terms of the behavior of the radiation field, the physical properties of the detector, and the statistical behavior of the detector output. Both incoherent and coherent detection are treated in a unified manner, after which selected applications are analyzed, following an analysis of atmospheric effects and signal statistics. The material was developed during a one-semester course at M.I.T. in 1975, revised and presented again in 1976 at Lincoln Laboratory, and rewritten for publication in 1977. Chapter 1 reviews the derivation of Planck's thermal radiation law and also presents several fundamental concepts used throughout the text. These include the three thermal distribution laws (Boltzmann, Fermi-Dirac, Bose Einstein), spontaneous and stimulated emission, and the definition and counting of electromagnetic modes of space. Chapter 2 defines and analyzes the perfect photon detector and calculates the ultimate sensitivity in the presence of thermal radiation. In Chapter 3, we turn from incoherent or power detection to coherent or heterodyne detection and use the concept of orthogonal spatial modes to explain the antenna theorem and the mixing theorem. Chapters 4 through 6 then present a detailed analysis of the sensitivity of vacuum and semiconductor detectors, including the effects of amplifier noise.

Strictly off limits to the public, Plum Island is home to virginal beaches, cliffs, forests, ponds -- and the deadliest germs that have ever roamed the planet. Lab 257 blows the lid off the stunning true nature and checkered history of Plum Island. It shows that the seemingly bucolic island in the shadow of New York City is a ticking biological time bomb that none of us can safely ignore. Based on declassified government documents, in-depth interviews, and access to Plum Island itself, this is an eye-opening, suspenseful account of a federal government germ laboratory gone terribly wrong. For the first time, Lab 257 takes you deep inside this secret world and presents startling revelations on virus outbreaks, biological meltdowns, infected workers, the periodic flushing of contaminated raw sewage into area waters, and the insidious connections between Plum Island, Lyme disease, and the deadly West Nile virus. The book also probes what's in store for Plum Island's new owner, the Department of Homeland Security, in this age of bioterrorism. Lab 257 is a call to action for those concerned with protecting present and future generations from preventable biological catastrophes.
