Together, they were awarded the Nobel Prize for Physics in 1903, and she received another one, for Chemistry, in 1911.Her work with radioactive materials doomed her, however. She died of a blood disease in 1934.n 1911, after Pierreâs death, Marie was awarded a second Nobel Prize in Chemistry for her discovery of the elements polonium and radium. Later years. Marie continued to do research in radioactivity.
