How did Marie Curie discovery impact the world?

Indefatigable despite a career of physically demanding and ultimately fatal work, she discovered polonium and radium, championed the use of radiation in medicine and fundamentally changed our understanding of radioactivity.

What happened to Marie due to exposure to radium?

Answer: Marie Curie died on 4 July 1934, in Savoy, France. She died of aplastic anaemia, a blood disease that often results from exposure to large amounts of radiation.

What did Marie Curie accomplish?

Marie Curie is remembered for her discovery of radium and polonium, and her huge contribution to finding treatments for cancer.

How did Marie Curie change the model of the atom?

This discovery was revelatory because until then atoms were thought to be indivisible. But Curie’s theory of radioactive decay proved the existence of subatomic particles. It showed that unstable atoms could undergo changes (by emitting energy and electrons)and could give rise to completely different atoms as a result.

How has Marie Curie changed the world for kids?

Marie Curie is considered to be one of the most influential scientists of all time. She was the first woman to win a Nobel prize and the only person to win Nobel prizes in two different sciences: physics and chemistry. Marie Curie discovered radioactivity and changed the way scientists understood the atom.

Did Marie Curie know radium was poisonous?

She had no idea of the dangers of radioactivity Today, more than 100 years after the Curies’ discovery of Radium, even the public is kept well aware of the potential dangers associated with the exposure of the human body to radioactive elements.

How did the discovery of radioactivity change the world?

The discovery of radioactivity changed our ideas about matter and energy and of causality’s place in the universe. It led to further discoveries and to advances in instrumentation, medicine, and energy production. It increased opportunities for women in science.

Did Marie Curie save lives?

Although, quite ironically, she helped save a million lives (directly) by using radiation, which has developed drastically in recent times to have saved millions more!
