Madame Curie's message

Madame Curie, Marie Curie, was a French scientist originally from Poland. She and her husband, pierre curie, were both early radioactive researchers. They discovered the radioactive elements polonium and radium, so they worked with the French physicist Henry. Becquerel shared the 1903 Nobel Prize in Physics. Later, Madame Curie continued to study the application of radium in chemistry and medicine, and won the 19 1 1 Nobel Prize in chemistry for separating pure metal radium.

Madame Curie's maiden name is Manya. Scaro Doska (in Polish, Manya Sklodowska) was born in Warsaw, Poland, on June 7, 2008 at 1867 165438, when Poland was under Russian rule. Manya's parents were both teachers, and soon after her birth (she was their fifth child), they lost their teaching posts. To make ends meet, they packed some students' meals. To this end, young Manya had to help cook and work long hours every day. However, she still won the excellent medal for middle school students. After graduating from middle school, she became a tutor. 189 1 year, she went to Paris and entered the University of Paris to study physics and mathematics. When she graduated, she ranked first in her class. 1894 She and French physicist Pierre. Curie met and they got married the next year.

Since 1896, the curies have studied radioactivity together. Prior to this, German physicist wilhelm rontgen 1845- 1923 discovered X-rays (so he won the Nobel Prize in Physics with 190 1), and becquerel discovered that uranium salts emit similar rays. Madame Curie found that thorium (Th) is also radioactive, and the radioactivity of pitchblende is stronger than any content of uranium and thorium, which cannot be explained. The curies searched hard and finally announced the discovery of radioactive element radium in 1898. They finally produced 1g pure radium chloride from 8 tons of waste pitchblende, and put forward the view that-ray (now known to be composed of electrons) is a negatively charged particle.

1906 pierre. Unfortunately, Madame Curie was killed by a carriage, but Madame Curie did not fall down because of it. She went on with her research. In 19 10, she discovered actinide Ac(Andre Debierne, 1874- 1949) from pitchblende.

19 14 When World War I broke out, Madame Curie equipped an ambulance with X-ray equipment and drove to the front. The International Red Cross appointed her as the head of the radiation rescue department. With the help of her daughters Irene Curie and Martha Klein, Madame Curie opened a course at the Radium Institute for nurses and doctors in military hospitals, teaching them how to use the new technology of X-rays. In the late 1920s, Madame Curie's health began to deteriorate. Long-term radiation exposure made her suffer from leukemia, and finally1died on July 4, 934. A few months before this, her daughter Elon and her son-in-law Joliot-Curie announced the discovery of artificial radioactivity (for which they won the 1935 Nobel Prize in chemistry).

Madame Curie was poor for most of her life, and the arduous process of extracting radium was completed under harsh conditions. The Curies refused to patent any of their discoveries, so that everyone could use their discoveries freely. They used the Nobel Prize and its prize money for future research. One of the outstanding applications of their research work is the application of radiation to treat cancer.
