4. Discovery Found out that uranium ore were a great deal more radioactive than than pure element uranium Polonium was a black powder 330 times more radioactive than uranium which is in pitchblende She discovered radioactive elements polonium and radium She improve the understanding of radioactivity and effects of x-rays

5. Problems faced Had to work on the pitchblende without uranium to grind,dissolve, filter, precipitating, collect, redissolve, crystallising and recrystallising. Had raw and inflamed hands to work as they persevered, ignoring the dangers and they continued handling the highly radioactive materials

6. Achievements 1 st Nobel Prize in 1903 for Physics (with Pierre Curie and Professor Becquerel) 2nd Nobel Prize in 1911 for Chemistry for creating means of measuring Radioactivity In World War l, she worked to develop small, mobile x-ray units to diagnose injuries near battlefront Ellan Richards Research Prize(1921) Grand Prize du’ Marquis d’ Argenteuil(1923) Cameron Prize from Edinburgh University (1931)

7. Death & Legacy Died of Pernicious anaemia which developed after years of exposure of radiation Left with 2 daughters, Irene(born in 1988) & Eve (1904) Irene worked on the nucleus of atom with her husband, Frederic Joliot & died of radiation-related illness, leukaemia Irene’s daughter, Dr Helene Langevin Joliot pursued a career in nuclear physics & became a research emeritus of National Centre for Scientific Research in Paris Eve became a journalist and writer First woman to be awarded a place in Patheon Life as a scientist which flourished because of her ability to observe, deduce and predict
