She invented polonium.
Marie Curie was also known for her pioneering research in the fields of x-ray imaging and nuclear physics. She was the first woman to win a Nobel Prize and remains the only person to win Nobel Prizes in two different scientific fields. Additionally, she established the Curie Institutes in Paris and Warsaw, which continue to be leading research institutions in the fields of radiology and oncology.
Marie Curie did not invent the X-ray machine; this was Mr. Rontgen who figured out how to produce radiographs. Ms. Curie was one of the pioneers who first identified and described radiation; this is why radiation levels are often measured in curies - the unit was named in her honor.
Marie Curie also discovered polonium. Her husband Pierre helped in the investigation also. She started off by studying a variety of chemical compounds that contained uranium. She discovered that the strength of the rays that came out depended only on the amount of uranium in the compound. It had nothing to do with whether the material was solid or powdered, dry or wet, pure or combined with other chemical elements. If you had a certain amount of uranium a certain number of uranium atoms-then you got a certain intensity of radiation. Nothing else made a difference. The Nobel Prize in Physics 1903 was divided, one half awarded to Antoine Henri Becquerel "in recognition of the extraordinary services he has rendered by his discovery of spontaneous radioactivity",the other half jointly to Pierre Curie and Marie Curie.
Marie Curie was known to be quiet and reserved in her personal life. She was described as being introverted and focused on her scientific work rather than socializing.
Marie Curie is famous for discovering the element Radium, previously unknown. The history of this is an interesting progression, like so much in science. The physicist Roentgen discovered X-rays, and found that they would pass through solid matter, and also that they would affect photographic plates. The scientist Becquerel discovered that a mineral called pitchblende would affect these plates even through their wrappers, and suspected that the mineral was producing X-rays. This was puzzling, because Roentgen made X-rays using high voltages in a vacuum chamber, while pitchblende just sat there but somehow did the trick. Curie thought that there must be something unknown in pitchblende. She bought tons of it, and started trying to isolate something else from it. Eventually she managed to get a few grams of something from the tons of original stuff. This new substance had remarkable properties. It was always warmer than its surroundings; it shone in the dark, and it produced something very like X-rays. The rate at which these three things were produced did not seem to diminish with time. She had produced a radioactive substance with a long half-life. Because it radiated light, heat and X-rays it became called Radium.
Yes Marie Curie was brave because she took risk and she helped people by telling them why is radiation and polonium bad and she was the one who discovered it, because of her we know why radiation and polonium is bad for us. Hope that answer helped you for your presentation or something else
