Google on Saturday paid Řtefania Mărăcineanu her 140th birthday by donating a doodle. Mărăcineanu, a Romanian physicist, was one of the foremost women in the field of radioactivity detection and research.
The physicist built the first Romanian radioactivity research laboratory on his return after working for four years at the Astronomical Observatory in Meudon.
He spent his time researching the artificial rain he visited Algeria to test it.
He then did graduate research at the Radium Institute in Paris. The Radium Institute soon became a global center for the study of radioactivity under the direction of Physicist Marie Curie. Mărăcineanu began working on his PhD thesis in polonium, something Curie discovered.
While studying half the life of polonium, Mărăcineanu noticed that half the life seemed to depend on the type of metal on which it was placed. This made him wonder if the alpha rays from polonium had transferred certain atoms of iron to radioactive isotopes.
Mărăcineanu’s work led to the first example of synthetic radioactivity. A physicist completed his PhD in physics within two years at the Sorbonne University in Paris.
