The science and art of radiation protection or health physics grew out of the discoveries of x-rays and radioactivity near the end of the nineteenth century. The x-ray, discovered by German physicist Wilhelm Konrad Roentgen in 1895, was reported to the world shortly after the first of the year in 1896. His discovery was a scientific bombshell, and was received with extraordinary interest by both scientist and laymen. Many scientist dropped other concentrations of research to pursue …
