Later years

Marie continued to do research in radioactivity. When World War I broke out in 1914, she suspended her studies and organized a fleet of portable X ray machines for doctors on the front.After the war, she worked hard to raise money for her Radium Institute, including a trip to the United States. But by 1920, she was suffering from medical problems, likely due to her exposure to radioactive materials. On July 4, 1934, she died of aplastic anemia, a blood disease that is often caused by too much exposure to radiation.Maries was buried next to Pierre, but in 1995, their remains were moved and interred in the Pantheon in Paris alongside France's greatest citizens.The Curies received another honor in 1944 with the discovery of the 96th element on the Periodic Table of the Elements, which was named curium.
