Mari cure was given loads of plutonium by the poland government and her research on this element lead to the discovery and radium where one night in one of her store room an abandoned box and plutonium was glowing and that led to the invention of radium.

Marie curie also invented polonium and thats how the country poland got its name.

Marie Curie 1867-1934
Dr. Marie Curie is known to the world as the scientist who discovered radioactive metals i.e. Radium & Polonium.
Marie Curie was a Polish physicist and chemist who lived between 1867-1934. Together with her husband, Pierre, she discovered two new elements (radium and polonium, two radioactive elements that they extracted chemically from pitchblende ore) and studied the x-rays they emitted. She found that the harmful properties of x-rays were able to kill tumors. By the end of World War I, Marie Curie was probably the most famous woman in the world. She had made a conscious decision, however, not to patent methods of processing radium or its medical applications.

Marie Curie was born November 7, 1867 in Poland and died on July 4, 1934. Her co-discovery with her husband Pierre Curie of the radioactive elements radium and polonium represents one of the best known stories in modern science for which they were recognized in 1901 with the Nobel Prize in Physics. In 1911, Marie Curie was honored with a second Nobel prize, this time in chemistry, to honor her for successfully isolating pure radium and determining radium's atomic weight.

As a child, Marie Curie amazed people with her great memory. She learned to read when she was only four years old. Her father was a professor of science and the instruments that he kept in a glass case fascinated Marie. She dreamed of becoming a scientist, but that would not be easy. Her family became very poor, and at the age of 18, Marie became a governess. She helped pay for her sister to study in Paris. Later, her sister helped Marie with her education. In 1891, Marie attended the Sorbonne University in Paris where she met and married Pierre Curie, a well-known physicist.

Marie cury was first 'who invent radium. She invent this, by million grams of tarcaol, & she get only 2 gram radium.

Srivinayak said: (Sep 30, 2011)  
What did Benjamin franklin invent?

Gayatri said: (Nov 6, 2011)  
She invented it while he was doing an experment with radiom and she found radioactive element radiom.

Ragsi said: (Feb 14, 2012)  
First it was Henry Bequerel of France who discovered the phenomenon of radio activity. Then Madam Curie along with Pierre curie found uranium and polonium.

Surekha said: (Mar 1, 2012)  
Madem curie got two noble prizes, madem curie family got 5 noble prizes. Madem curie-2, her husbend piere curie-1 in 1903 alog with his wife and another man. In 1906 piere curie died in road accident, madem curie daughter irene curie and her husbend got noble prize for artificial radioactivity.

Madam curie separated radium from pitch blende.

Mayank said: (Jun 6, 2012)  
Marie curie was a great invented and radioactive redhum.

Rakesh said: (Jun 12, 2012)  
Because he only founded radio active element while the proceesdoing that he comes to know.

She was awarded half of the Nobel Prize for Physics in 1903, for their study into the spontaneous radiation discovered by Becquerel, who was awarded the other half of the Prize. In 1911 she received a second Nobel Prize, this time in Chemistry, in recognition of her work in radioactivity.

Amit Walia said: (Nov 17, 2012)  
She discovered radioactive element i.e. Radium in 1898.

Madam curie awarded for noble prize for this radium invention.

Stylish said: (Jun 22, 2013)  
Marie Curie was a physicist and chemist best known for her work on radioactivity; however, she also discovered the elements polonium and radium. She was awarded two Nobel Prizes " one in physics which she won jointly with her husband and Henri Becquerel, and another in chemistry " and was the first person to win two Nobel Prizes. She is still one of only two (along with Linus Pauling) to accomplish that feat. Curie is responsible for establishing the theory of radioactivity, but unfortunately she unwittingly also discovered the fatal effect radioactivity can have on your health; she died on July 4, 1934, of aplastic anemia caused by radiation exposure.

He is the great scientist of world so I say thanks marie curie.

In her family most of the members are got nobel prizes.

Radium is a chemical element with symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. The color of pure radium is almost pure white, but it readily oxidizes on exposure to air, becoming black in color.

Frank said: (Nov 13, 2014)  
Curie died in 1934 at the sanatorium of Sancellemoz (Haute-Savoie) , France, due to a plastic anemia brought on by exposure to radiation including carrying test tubes of radium in her pockets during research and her World War I service in mobile X-ray units created by her.

LONG LIVE Marie Curie.

Marry curie first discovered the medicine for cancer.

Rahul said: (May 14, 2015)  
Radium, in the form of radium chloride, was discovered by Marie Curie and Pierre Curie in 1898. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later.

Abinash said: (May 15, 2015)  
She died by researching about radium by cancer.

Vijay said: (Dec 28, 2015)  
Radium was discovered by Marie Sklodowska-Curie and her husband Pierre Curie on 21 December 1898, in a uraninite sample.

When was Marie Curie died?

Murali said: (Mar 3, 2016)  
In 1895, Wilhelm Roentgen discovered the existence of X-rays, though the mechanism behind their production was not yet understood. In 1896, Henri Becquerel discovered that uranium salts emitted rays that resembled X-rays in their penetrating power. He demonstrated that this radiation, unlike phosphorescence, did not depend on an external source of energy but seemed to arise spontaneously from uranium itself. Influenced by these two important discoveries, Marie decided to look into uranium rays as a possible field of research for a thesis.
