Marie Curie and the radiation

She was the first person to receive two Nobel Prizes, in Physics and Chemistry, and the first woman who worked as a professor at the University of Paris.

Marja Sklodowska, known as Marie Curie, was a brilliant scientist of Polish origin who was born in Warsaw on November 7, 1867.

Already in 1891 he went to the city of Paris, where he enrolled in the science course of the prestigious Sorbonne University. Two years later he finished his studies in physics as number one of his promotion.

In 1894 she met her husband, Pierre Curie. Although both worked in the field of magnetism, Marie Curie devoted herself to the study of uranium radiation, interested in the recent discoveries made around the new types of radiation by Wilhelm Roentgen and Antoine Henri Becquerel.

Thus, using the piezoelectric techniques developed by Pierre, Marie measured the radiation of the pechblende, a mineral that contains uranium. Thus, he observed that the radiation of this mineral was more intense than those produced by pure uranium, so he realized that there should be unknown elements that were more radioactive than uranium.

Marie Curie was the first to use the term "radioactive" to discover all those elements that emit radiation when their nuclei decompose.

After finishing his work on magnetism, Pierre Curie joined his wife's investigation. In this way, the marriage discovered in 1898 two new radioactive elements: polonium and radium.

As a result of this discovery, both were recognized with the Nobel Prize in Physics, which they shared with Becquerel, and Marie Curie became the first woman to receive this award.

After Pierre Curie died run over, Marie Curie continued her research, getting a second Nobel in Chemistry for her studies on radio and its compounds.

Finally, Marie Curie died in France on July 4, 1934 as a result of a pernicious anemia caused by long exposure to radiation
