Google on Saturday paid Ștefania Mărăcineanu a tribute on her 140th birthday by dedicating a doodle

She was born on June 18, 1882 in Bucharest. Her research on Polonium led to what is most likely the first example of artificial radioactivity.

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.

Her research on Polonium led to what is most likely the first example of artificial radioactivity.

She decided to pursue graduate research at the Radium Institute in Paris.

The Radium Institute was quickly becoming a worldwide center for the study of radioactivity under the direction of physicist Marie Curie.

The doodle features Maracineanu working on Polonium in a laboratory. Maracineanu dedicated her time to researching artificial rain.

Mărăcineanu, a Romanian physicist, was one of the pioneering women in the discovery and research of radioactivity.

While studying the half-life of polonium, Mărăcineanu realised that the half life seemed dependent on the type of metal it was placed on.

This led her to wonder if the alpha rays from the polonium had transferred some atoms of the metal into radioactive isotopes.

HAPPY 140TH BIRTH ANNIVERSARY
