This book remembers and commemorates many brave radiation scientists, most of whom are no longer with us. These scientists published findings that radiation risks were more dangerous than officially accepted at the time. However they often suffered as a result from official displeasure, defamatory articles, and public obloquy. Scientific findings, especially recently, have revealed that these defamed and/or disadvantaged scientists were actually correct in their assessments that official risk factors for radiation were too low and needed to be increased. The lives of these scientists are discussed, from early radiation pioneers including Ernest Rutherford, Hermann Mueller and Linus Pauling, to contemporary scientists such as Steve Wing.
