What did Marie Curie discover?
Marie Curie 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 – a revolutionary discovery!
