Marie Curie always scorned the precautions against radiation which she imposed on her pupils. She developed many of the symptoms associated with radiation exposure including cataracts and burned hands. By the early 1930s, she had been handling radium for 35 years and her blood content was abnormal. She eventually died in 1934 from ‘aplastic pernicious anaemia', now termed leukaemia. Her doctor noted that ‘the bone marrow did not react, probably because it had been injured by a long accumulation of radiations'. Professor Claude Regaud of the Radium Institute in Paris, wrote: ‘Madame Curie can be counted among the eventual victims of the radioactive bodies which she and her husband discovered'.
