Marie Curie (7 ноя 1867 г. – 4 июл 1934 г.)

Описание:

Studied the radiation of all compounds containing the known radioactive elements, including uranium and thorium, which she later discovered was also radioactive. She also found out that: you can exactly measure the strength of the radiation from uranium; the intensity of the radiation is proportional to the amount of uranium or thorium in the compound - no matter what compound it is; the ability to emit radiation does not depend on the arrangement of the atoms in a molecule; it must be linked to the interior of the atom itself. discovered two new radioactive elements: radium and polonium
