Madame Curie’s character: selfless dedication, dedication, self-sacrifice, courage to explore, dare to practice, continuous innovation, not afraid of hard work, indifferent to fame and fortune, talented and intelligent, forgetting to eat and sleep, and working hard.

In 1903, the Curies and Becquerel won the Nobel Prize in Physics together for their research on radioactivity. In 1911, they won the Nobel Prize in Chemistry again for the discovery of the elements polonium and radium. Thus becoming the first person in the world to win two Nobel Prizes.

Marie Curie’s achievements include pioneering the theory of radioactivity, inventing technology for separating radioactive isotopes, and discovering two new elements, polonium and radium. Under her guidance, radioactive isotopes were used for the first time to treat cancer. Due to long-term exposure to radioactive substances, Marie Curie died of aplastic pernicious anemia on July 4, 1934.

In her experimental research, Madame Curie designed a measuring instrument that can not only detect the presence of rays in a certain substance, but also measure the intensity of the rays. weak. After repeated experiments, she found that the intensity of uranium rays is proportional to the amount of uranium in the material, and has nothing to do with the state of uranium existence and external conditions.

Madame Curie conducted a comprehensive examination of known chemical elements and all compounds, and made an important discovery: an element called thorium can also automatically emit invisible rays. It shows that the phenomenon that elements can emit rays is not just a characteristic of uranium, but a unique characteristic of some elements.
