Marie Curie used lead blocks as desk paper to protect her notes and notebooks from the ionizing radiation emitted by the radioactive materials she worked with, in order to minimize her exposure to radiation.
Marie Curie, born Maria Sklodowska, was a Polish physicist and chemist who became a French citizen. She was born on November 7, 1867 in Warsaw, in present-day Poland, and died on July 4, 1934 in Sallanches, Haute-Savoie, France. She is famous for her pioneering work on radioactivity.
Marie Curie began her scientific career in Poland, where she studied physics and mathematics at the University of Warsaw. At the time, women were not allowed to attend university in Poland, but Marie Curie managed to take classes clandestinely.
In 1891, Marie Curie moved to Paris to continue her studies at the Sorbonne. It was there that she met Pierre Curie, a French physicist whom she married in 1895. Together, they conducted research on radioactivity, a phenomenon discovered a few years earlier by physicist Henri Becquerel.
Marie Curie's early research laid the foundation for her exceptional scientific career. Her work on radioactivity not only revolutionized physics and chemistry at the time, but also paved the way for many important discoveries in the field of radioactivity and nuclear physics.
Marie Curie discovered polonium in 1898, while collaborating with her husband, Pierre Curie. They isolated this radioactive element from uranium. Polonium was named in honor of Marie's native Poland. Shortly thereafter, in 1898 as well, the Curies announced the discovery of radium, another radioactive element. They were able to extract radium from pitchblende, a mineral containing uranium.
These discoveries revolutionized the fields of physics and chemistry, leading to new understandings of radioactivity and chemical elements. Polonium and radium have led to major advances in medicine, particularly in cancer treatment. These elements also laid the foundation for radiotherapy, which is now a common method for cancer treatment.
Marie Curie was exposed to high levels of radiation throughout her scientific career. Working with radioactive elements such as radium and polonium, she was constantly surrounded by ionizing radiation, unaware at the time of the potential dangers to her health. The harmful effects of radiation began to show over the years, causing health problems such as cataracts and illnesses due to prolonged exposure to radiation.
Despite her major contribution to science, Marie Curie was not aware of the risks associated with handling radioactive substances. Her pioneering work in this field exposed her to levels of radiation far beyond current laboratory safety standards. The deleterious effects of this exposure eventually took a toll on her health, contributing to her premature death at the age of 66.
The radiation to which Marie Curie was exposed not only affected her own health, but also had consequences for her descendants. Several members of her family, including her daughter Irène Joliot-Curie, were also affected by health problems related to radiation. This story highlights the dangers of ionizing radiation and underscores the importance of taking adequate protective measures when handling radioactive substances.
Marie Curie quickly became aware of the dangers of radiation to her health. To protect herself, she implemented preventive measures, including the use of lead blocks. Lead is a dense material that has the ability to effectively stop the ionizing radiation emitted by radium and polonium, two elements she discovered. By wrapping her measuring instruments and radioactive samples in lead sheets, Marie Curie reduced her exposure to radiation and minimized health risks. This pioneering practice laid the foundation for modern radioprotection and helped raise awareness of the importance of protecting oneself from the harmful effects of ionizing radiation.
Marie Curie left a lasting legacy in modern science. Her groundbreaking work on radioactivity paved the way for numerous important discoveries and applications. In recognition of her exceptional achievements, Marie Curie was the first person to receive two Nobel Prizes in different scientific fields. Her influence extends beyond her own research, inspiring generations of scientists to pursue advancements in areas such as nuclear physics, medicine, and chemistry. Her dedication to science and innovative spirit remain sources of inspiration for all those who pursue knowledge and discovery.
