Today (September 12, 1897) is the birthday of Irene Joliet Curie, the daughter of Marie Curie, Nobel Laureate, who discovered new radioactive elements artificially.


Irene Joliot-Curie was born on September 12, 1897, in Paris, France. She is the daughter of the famous Nobel couple Marie Curie and Pierre Curie and is a French scientist. By 1906, Irene was clearly proficient in mathematics. And his mother chose to focus on it instead of public school. Mary formed a collaborative effort with many eminent French scholars, including the leading French physicist Paul Lange. It also included a private gathering of nine students who were the children of some of the most famous academics in France. Each contributed to the education of each other in their respective homes. The co-curriculum is diverse and covers not only the principles of scientific and scientific research but also different disciplines such as Chinese and sculpture. Placed greater emphasis on self-expression and sport. Irene studied in this environment for about two years.

When Irene was thirteen, Irene and her sister Au were sent to Poland to spend the summer with Aunt Brona (Mary's sister). Irene's education was very rigorous. Each day of that interval she had a German and trigonometry lesson. By 1914 Irene had re-entered a traditional learning environment by attending high school at the College Sevignay in central Paris. He then went to the Faculty of Science in Sorbonne. He completed his bachelor's degree until 1916 when his studies were hampered by World War II. Irene took a nursing course in college to help her mother become an assistant to Marie Curie. She set aside her mother and began her career as a nursing radiographer on the battlefield. But a few months later he was alone in a radiation facility in Belgium. 


He taught doctors how to detect small pieces in bodies using radiation. He also learned how to repair equipment himself. He received a military medal for his assistance with X-ray facilities in Belgium. After the war, he returned to Sorbonne in Paris in 1918 to complete his degree in mathematics and physics. Irene later worked as her mother's assistant at a radium company built by her parents. His doctoral dissertation is on the alpha decay of polonium, an element discovered by his parents (including radium) and named after Mary's birthplace, Poland. Irene became a physician in 1925. 

Towards the end of his doctorate in 1924, Irene Curie was asked to teach young chemist Frederick Joliet the precise laboratory techniques needed for radiochemical research. She later married him. Since 1928, Joliet-Curie and her husband, Frederick, have co-founded nuclear research. In 1932, Joliet-Curie and her husband, Frederick, approached Marion's polonium in its entirety. Experiments were carried out using gamma rays to identify positron. Although their experiments identified both positrons and neutrons, they failed to explain the significance of the results. The findings were later requested by Carl David Anderson and James Chadwick, respectively. While these findings are truly magnificent, J.J. Just as Thompson discovered the electron in 1897, they eventually transformed John Dalton's model of atoms into solid spherical particles.

However, in 1933, Joliet-Curie and her husband were the first to discover the exact weight of a neutron. Joliet-Curie continued to seek his name in the scientific community. In doing so they developed a new theory from an interesting experiment they conducted. During the experiment using alpha rays against aluminum, only protons were detected. They proposed that protons be converted into neutrons and positrons based on the undetectable electron and positron pair. Then in October 1933, this new doctrine was taken to the Seventh Soul Conference. The Soulway Conference consisted of prominent scientists from the physics and chemistry community. Irene and her husband presented their theory and conclusions to fellow scientists. But they received criticism from most of the 46 scientists who attended. However they were later able to develop the controversial theory.

 

In 1934, Joliet-Curie finally made the discovery that sealed their place in scientific history. Joliet-Curie, who built the work of Marie and Pierre Curie to isolate naturally occurring radioactive elements, realized the alchemist's dream of transforming one element into another. Formation of radioactive nitrogen from boron, radioactive isotopes of phosphorus from aluminum and silicon from magnesium, the natural stable isotope of aluminum with alpha particles (helium) forming an unstable isotope of phosphorus. 27Al + 4He → 30P + 1n. This first discovery is formally known as positron emission or beta decay. There a proton in the radioactive nucleus turns into a neutron and emits a positron and an electron neutrino.


Meanwhile, the use of radioactive materials in medicine grew. This invention allowed the production of radioactive materials quickly, cheaply, and in large quantities. She and her husband, Frederick Joliet-Curie, discovered new radioactive elements artificially and won the 1935 Nobel Prize in Chemistry. Their family is proud to have won the most Nobel Prizes from a family to date. Joliet-Curie was made professor of science. Irene Joliet Curie, daughter of Nobel Laureate Marie Curie, died of leukemia on March 17, 1956 at Curie Hospital in Paris. This may be due to polonium-210 radiation.
