Google on Saturday celebrated the 140th birth anniversary of Ștefania Mărăcineanu, one of the pioneering women in the discovery and research of radioactivity.

Mărăcineanu graduated with a physical and chemical science degree in 1910, and began her career as a teacher at the Central School for Girls in Bucharest. During this time, she earned a scholarship from the Romanian Ministry of Science and later decided to pursue graduate research at the Radium Institute in Paris.

Notably, at that time, the institute was becoming a center for the study of radioactivity worldwide under the direction of physicist Marie Curie. Maracineanu began working on her Ph.D. thesis on polonium — the same element which was discovered by Curie.

During her research on the half-life of polonium, Mărăcineanu noticed that the half-life seemed dependent on the type of metal it was placed on. This got her thinking if the alpha rays from the polonium had transferred some atoms of the metal into radioactive isotopes. Her research led to what is most likely the first example of artificial radioactivity.

Stefania Maracineanu Biography, Wiki

Ștefania Mărăcineanu (June 18, 1882 – August 15, 1944) was a Romanian physicist. Ștefania Mărăcineanu. Stefania Maracineanu.

Born in Bucharest, the capital of Romania, not much is known about Maracineanu’s personal life, but she is said to have had an unhappy upbringing for years. He graduated in 1910 in physical and chemical sciences from the University of Bucharest. and its application to the measurement of wavelengths.

After graduating, Maracineanu taught at secondary schools in various Romanian cities. After World War I he traveled to Paris to continue his studies.In 1919 he studied radioactivity with the famous Marie Curie at the Sorbonne. Until 1926 he did research with Curie at the Radium Institute, where he also received his doctorate.

Maracineanu studied the half-life of polonium and developed an observation on radioactive isotopes that formed the basis of the 1935 Nobel Prize for Joliot Curies for discovering artificial discoveries. However, Maracineanu was the first to make the discovery, the data shows.

Maracineanu also conducted experiments to prove the link between radioactivity and rain, and the link between rain and earthquakes. The physicist breathed her last in 1944 and lost her life to cancer which she allegedly contracted from exposure to radiation.

Stefania Maracineanu Career

Mărăcineanu received her degree in physical and chemical sciences in 1910, going on to teach at the Central School for Girls in Bucharest. She then traveled to Paris to do research at the Radium Institute with Marie Curie from around 1919 until 1926, where she also received her doctorate in 1924.

At the Radium Institute, Mărăcineanu researched the half-life of polonium and devised methods of measuring alpha decay.

This work led her to believe that radioactive isotopes could be formed from atoms as a result of exposure to polonium”s alpha rays. An observation that would lead to the Joliot-Curies” 1935 Nobel Prize.

She also investigated the possibility of sunlight inducing radioactivity. Work which was contested by other researchers.

Mărăcineanu went on to work at the Paris Observatory until 1930, after which she returned to Romania and performed experiments investigating the link between radioactivity and rainfall, and rainfall with earthquakes.

She died in 1944, though the exact date and reason are unknown. She claimed, with the help of the Romanian Science Academy that she discovered the artificial radioactivity and she deserved to share the Nobel prize with Irene Curie, thus leading to isolation from the foreign science world.
