Marie Curie is one of the world’s renowned female physicists and has spent most of her adult life dedicated to the sciences of physics and chemistry. She revolutionized the study of nuclear chemistry and radioactivity, thus setting a precedent for us, even though some of the activities she partook was detrimental. Although Marie Curie furthered the study of radioactivity and nuclear weapons, I believe that she should have participated in better safety measures and been cautious with the materials she was utilizing with her experiments, because her work, ultimately cost her life.Born on November 7, 1867 in Warsaw, Russian Empire (known as Warsaw, Poland today) she was known as Maria Salomea Sk?odowska, not Marie Curie. At school, she excelled in the fields of sciences and mathematics, and desired for a career in those subjects. After graduating secondary school at the top of her class, she took a year break to calm her nerves (Mclafferty). After taking a year break, Maria and her sister Bronya enrolled in a “Floating University” a secretive university in which Polish scientists, philosophers, and historians taught. At this university, Maria and Bronya studied anatomy, natural history, and sociology. After graduating, both sisters wanted to attend the University of Paris (also known Sorbonne). Bronya wanted to become a doctor, while Maria wanted to continue her studies of physics and chemistry. To help fund university studies, Maria took on the role of being a governess, and her plan was to give Bronya her pay and in return she will fund Maria’s education after becoming attaining her medical degree. After eight years Maria entered Sorbonne to continue her studies. At Sorbonne, Maria (now known as Marie) felt a sense of freedom and liberty that she had never felt in her native country. Like secondary school, Maria worked hard and spent more time studying rather than eating or doing other things. This did pay off when she graduated at the top of her class once again. Yet she was not satisfied, because she also wanted to obtain a mathematics degree. After earning a scholarship for gifted Polish students, Marie spent another fifteen months in Paris to finish her degree .Through some friends, she met Pierre Curie, a prominent French Scientist. (List source) After graduating second in her class for mathematics, Pierre proposed to Marie for the first time. She refused a few times afterwards, but finally gave in. Four months after Pierre obtained his Ph.D, they married. After they had wed, Pierre and Marie began working at the School of Physics and Chemistry. There they experimented on invisible rays emitted from uranium. The inspiration for their experiment came from Dr. Henri Becquerel, a French scientist who discovered these rays. He also demonstrated that the rays were able to pass through solid matter, fog and photographic film and caused air to conduct electricity. Aside from working on radiation, Marie noticed that samples of pitchblende, a metal that contains uranium ore, was more radioactive than the pure uranium that she was experimenting with. During her research, she noticed that there was more to the pitchblende than just uranium. The other material seemed to be in small amounts, yet was more radioactive. Since this material was unknown , Marie believed that she had discovered a new element. Afterwards she and Pierre began to experiment with this new element. “Pierre and Marie Curie set about working to search for the unknown element. They ground up samples of pitchblende, dissolved them in acid, and began to separate the different elements present…they extracted a black powder 330 times more radioactive than uranium” (MarieCurieUK). They named this newly discovered chemical element polonium, after Maria’s native homeland of Poland. Shortly after discovering Polonium, the Cures published evidence supporting the existence of a new element called radium, yet they did not have a sample of it. Marie decided to attain more pitchblende so she can show the existence of radium in a sample. After receiving pitchblende from an Austrian factory, she and Pierre began to remove uranium from it. As the experiment continued, both became sick, yet they blamed exhaustion. In reality both were suffering from radioactive poisoning (MarieCurieUK). Their hard work eventually paid off when they confirmed existence of this element in 1902. A year later, both Marie and Pierre won a Nobel Peace Prize alongside Henri Becquerel for their work on radioactivity. That same year, she received her doctorate from the University of Paris, making her the first woman in France to be given a Ph.D (Smithsonian). After Pierre’s death in 1906, Marie continued to perform radiation experiments and scientific research. In 1911, she won her second Nobel Peace Prize in the field of Chemistry. She also dedicated the rest of her life to utilizing radiation for humanitarian needs. During World War I, she aided the International Red Cross by supplying X-rays and radiological services that treated soldiers in the war zones (BBC). She helped about roughly one million soldiers throughout the war thanks to her dedication to help (Atomicheritage). A few years after the war, Marie headed to the United States for an American Tour promoting Radium. During her tour, many U.S. scientists and chemical companies were beginning to utilize radium for cancer treatments and military research at nearly one hundred thousand dollars per gram (Smithsonian). Now, Marie herself could not afford the element to perform experiments on. On July 4, 1934 Marie Curie died at the Sancellemoz Sanatorium in Passy, France at the age of 66. She died of aplastic pernicious anaemia, a disease that develops after prolonged exposure to radiation through her work and experiments. Although Marie Curie had revolutionized the utilization of radiation for humanitarian and scientific purposes, she should have taken note that radiation can affect her health in a negative way. For example, when she was first experimenting with it with her husband, both of them felt ill and exhausted. Those feelings are attributed to radiation poisoning, which can affect one in the long run.
