What unit is Curie?

It was the original radioactive unit, which has been abolished now.

Curie, code-named Ci, or Baker for short, is the world unified building unit "Curie" to commemorate Madame Curie, and is used as the unit of radioactive activity of substances.

Radioactivity refers to the number of atoms of radioactive elements or isotopes that decay every second. At present, the international unit of radioactivity is the Bekkerel (Bq), that is, one atom decays every second, and the radioactivity of one gram of radium is 3.7×10/0bq.

Marie Curie met her later husband, pierre curie, while studying at Sorbonne, and started their scientific career. Thus, the history of science left a glorious name-Madame Curie.

In order to extract 0. 1 g radium from 9 tons of asphalt residue, the Curies struggled for 45 months in a simple laboratory, constantly stirring every day, wearing dusty overalls, and the smoke made them cry.

Because of their discovery and research on radioactivity, the Curies won the 1903 Nobel Prize in physics, and Madame Curie became the first woman to win the Nobel Prize in history.

19 1 1 year, Madame Curie won the Nobel Prize in chemistry for successfully separating radium. In eight years, he won the highest scientific laurels in different disciplines twice, which is unprecedented and probably will never happen again.

Unexpectedly, after winning the Nobel Prize, Madame Curie did not apply for a patent for the method of refining pure radium, but made it public, which promoted the development of radiochemistry and medicine.

At that time, several friends advised her to apply for the patent right to produce radium. Madame Curie said: "This is not right, it is against the scientific spirit. We should not take advantage of this to make a profit. "

Madame Curie devoted her whole life to the great cause of science. She regarded scientific research as more important than her own health. In order to attend the World Physics Congress, she asked the doctor to postpone the kidney operation.

She once endured the fear of blindness and stubbornly carried out scientific research; At the last moment of her life, she was lying in bed with a high fever and still asked her daughter to report to her about the work in the laboratory.

For decades, Madame Curie personally "created" radioactive elements such as radium and polonium, which gave her great scientific glory, but also left her with poverty, lung disease, eye disease, gallbladder disease, kidney disease and final death.
