what serious discussion did the curies have when the radium industry was about to be born? What does this reveal about?
Answers
Answer:
Marie Curie is remembered for her discovery of radium and polonium, and her huge contribution to finding treatments for cancer.
Adopting the study of Henri Becquerel's discovery of radiation in uranium as her thesis topic, Curie began the systematic study of other elements to see if there were others that also emitted this strange energy. ... In 1898, they announced the discovery of two new elements, radium and polonium.

Answer:
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!
When she realized that some uranium and/or thorium compounds had stronger radiation than uranium, she made the following hypothesis: there must be an unknown element in the compound which had a stronger radiation than uranium or thorium. Her work aroused the interest of her husband, Pierre Curie, who stopped his own research on crystals and joined the “detective work” with his wife. And Marie was proven right: in 1898 the Curies discovered two new radioactive elements: radium (named after the Latin word for ray) and polonium (named after Marie’s home country, Poland).
