Questions: Marie Curie discovered radiation. She was also the first person to use radiation to treat tumors. Curie experimented extensively with radioactivity during her scientific career. Unfortunately, the damaging effects of radiation were not known then. Her exposure to radiation most likely was the cause of her blindness and early death. Still today, her scientific papers are considered too dangerous to handle without protective equipment. These documents are stored in lead-lined boxes. Even her cookbook is radioactive. Curie sacrificed her own life in an attempt to help others save their own lives.
