A card showing Marie Curie's opened research notebook. Text on right says "Marie Curie, celebrated as the 'mother of modern physics,' passed away from aplastic anemia, an uncommon condition associated with significant exposure to her renowned discoveries, the radioactive elements polonium and radium. Even after more than a century, a significant portion of her personal belongings, such as her clothing, furniture, cookbooks, and laboratory notes, retain their radioactive properties. Her laboratory research notebooks are contaminated with radium 226 and therefore are stored in lead-lined boxes at Bibliotheque National in Paris, France, where they are considered as national and scientific treasure.
