- Marie Curie's research notebooks remain dangerously radioactive, primarily due to radium-226, even after over a century.
- Radium-226 has a half-life of about 1,600 years, meaning it decays slowly; the notebooks will remain hazardous until around the year 3500.
- Curie handled radioactive materials without protective gear due to a lack of knowledge about their harmful effects, contaminating her belongings.
- The notebooks are stored in lead-lined boxes at the Bibliothèque nationale de France, accessible only under strict safety protocols and protective clothing.
- The contamination reflects the era when radioactivity was discovered but its dangers were not yet understood, a legacy of Curie's pioneering but perilous work.
- Curie's death from a blood disorder is linked to radiation exposure, making the notebooks a poignant reminder of the risks involved in scientific discovery.
