New Delhi: Google on Saturday celebrated the 140th birth anniversary of the Romanian physicist. Stefania Maracinenu with a doodle. marasinenu was one of the leading women in the discovery and research of radioactivity,
He was born on June 18, 1882 in Bucharest. His research on polonium most likely led to the first example of artificial radioactivity.
The doodle shows Maracinenu working on polonium in a laboratory. Maracineanu devoted his time to researching artificial rainfall.
Maracineanu graduated with a physical and chemical science degree in 1910, starting her career as a teacher at the Central School for Girls in Bucharest. While there, Maracineanu earned a scholarship from the Romanian Ministry of Science. She decided to pursue graduate research at the Radium Institute in Paris.
Under the direction of the physicist Marie Curie, the Radium Institute was rapidly becoming a worldwide center for the study of radioactivity. Maracineanu began work on his PhD thesis on polonium, an element discovered by Curie.
In the course of his research on the half-life of polonium, Maracinenu observed that the half-life depended on the type of metal on which it was cast. This led him to wonder whether the alpha rays from the polonium had transferred some of the metal atoms to radioactive isotopes. His research most likely resulted in the first example of artificial radioactivity.
Maracineanu enrolled at the Sorbonne University in Paris to complete his PhD in physics, which he earned in just two years! After working for four years at the Astronomical Observatory in Medon, she returned to Romania and founded her homeland’s first laboratory for the study of radioactivity.
Maracineanu devoted his time to researching artificial rainfall, including traveling to Algeria to test its results. She also studied the link between earthquakes and rainfall, becoming the first to report that earthquakes caused a significant increase in radioactivity at the epicenter.
In 1935, Marie Curie’s daughter Irene Curry and her husband received the joint Nobel Prize for the discovery of artificial radioactivity. Maracineanu did not contest for the Nobel Prize, but asked for his role in the discovery to be recognized.
His work was recognized by Romania’s Academy of Sciences in 1936, but he never received global recognition for this discovery.
