Under her guidance, people used radioisotopes to treat cancer for the first time. She is the first female professor at the University of Paris and the first person to win two Nobel Prizes. But she eventually died of leukemia because of exposure to radioactive substances. 1995, she moved and buried the Pantheon with her husband pierre curie.
Madame Curie made a comprehensive investigation of known chemical elements and all compounds, and made an important discovery: an element called thorium can automatically emit invisible rays, which shows that the phenomenon that an element can emit rays is not only the characteristics of uranium, but also the same characteristics of some elements.
She called this phenomenon radioactivity, and called elements with this property radioactive elements. They emit Marie Curie's rays, which are called "radiation". According to the experimental results, she also predicted that minerals containing uranium and thorium must be radioactive; Minerals that do not contain uranium and thorium are not necessarily radioactive.
She excluded those minerals that did not contain radioactive elements, concentrated on those that were radioactive, and accurately measured the radioactive intensity of elements. In the experiment, she found that the radioactive intensity of a pitchblende is much higher than expected, which shows that the mineral in the experiment contains a new unknown radioactive element, and the content of this element must be very small.
At this critical moment, her husband, pierre curie, also realized the importance of his wife's discovery, and stopped studying crystals to study this new element with her. They separated a substance mixed with bismuth from the ore, and its radioactive intensity far exceeded that of uranium, which was later listed as No.84 polonium in the periodic table.
Madame Curie devoted her life to discovery and research and made great contributions to mankind. She is worth learning.
