Detailed explanation-1: -Maria Skłodowska-Curie received the 1911 Nobel Prize for Chemistry for her discovery of radium and polonium (Fig. 1). The discovery of X-rays by Roentgen was a turning point in diagnostics.
Detailed explanation-2: -When Henri Becquerel investigated the newly discovered X-rays in 1896, it led to studies of how uranium salts are affected by light. By accident, he discovered that uranium salts spontaneously emit a penetrating radiation that can be registered on a photographic plate.
Detailed explanation-3: -Now, more than 80 years since her death, the body of Marie Curie is still radioactive. The Panthéon took precautions when interring the woman who coined radioactivity, discovered two radioactive elements, and brought X-rays to the frontlines of World War I.
