Marie Curie won her first Nobel Prize in 1903, for her work in nuclear physics.
She was the first woman to win a Nobel Prize, and remains the only woman to win twice.
Curie carried bottles of polonium and radium on her person for years. Radium’s most stable isotope has a half-life of around 1,600 years.
She died of aplastic anemia in 1934, which, it is believed, can be caused by regular or prolonged exposure to radiation.
Her notebooks are still radioactive and kept in lead-lined boxes. Before examining them, researchers are required to sign a waiver.
