[06:31.08]It was what they had been working so hard to find:pure radium.
[06:38.16]The matter that the Curies had discovered was radium.
[06:43.51]It looked like ordinary salt,
[06:47.35]but was one million times more radioactive than uranium.
[06:53.70]Its rays could go through every mineral except lead.
[06:59.03]In 1903 Marie received her doctor's degree for her study on radioactive matter.
[07:06.68]Altogether,between 1899 and 1904 she and Pierre wrote 34 articles about their work.
[07:16.74]Marie Curie never made money out of her research.
[07:21.78]She refused to treat these new discoveries as though they belonged to her,
[07:27.66]and instead shared all her knowledge with the whole scientific world.

[07:47.98]MADAME CURIE (2)
[07:51.85]Poloinum and radium were important discoveries.
[07:57.41]Polonium is used to set off a nuclear bomb.
[08:02.77]Radium,because of its powerful radioactive rays,can go deep into the human body.
[08:11.91]Scientists soon discovered that it could be used as a cure for cancer.
[08:19.07]In 1903 Marie and Pierre Curie were given the Nobel Prize for Physics.
[08:28.21]However,there is also a disadvantage which was not discovered for many years.
[08:37.04]Radioactive matter is dangerous to work with
[08:42.08]because it has a bad effect on the blood.
[08:46.52]Pierre and Marie noticed that after years of working with radioactive matter
[08:53.89]their boodies ached and their hands suffered too.
[08:59.06]In fact,radium not only damaged their health
[09:04.91]but also made the laboratory equipment with which they were working radioactive.
[09:12.57]Three of the Curies'notebooks were considered to be too radioactive to touch
[09:19.93]seventy-five years after they were written.
[09:24.61]In 1906 Pierre died in a road accident.
[09:30.67]Marie was deeply shocked by Pierre'sdeath,but was determined to go on working.
[09:38.82]Soon after the accident,she was given Pierre's post at the University of Paris
[09:45.95]as head of the Phy sics Department.
[09:50.21]So Marie Curie became the first woman in France to be a universiy professor.
[09:57.58]In 1911 she received a second Nobel Prize for her research,
[10:04.42]the first person in the world to receive two Nobel Prizes.
[10:10.98]After the First World War Madame Curie travelled to the USA,
[10:18.11]where she was received by the President
[10:22.05]and given a gram of radium for her future work.
[10:27.10]There were soon two Radium Institutes in the world,one in Paris and one in Warsaw.
[10:36.16]Marie was invited to many countries to give speeches about her work.
[10:41.62]For the last ten years of her life she was almost blind.
[10:47.99]The radium with which she had worked for many years
[10:52.85]had caused blindness and illness and finally a disease of the blood.
[10:59.62]She died in Paris at the age of 66.
[11:04.58]Today she is remembered and admired as a scientist.
[11:10.04]But she is also remembered for her determination and courage,
[11:15.71]her willingness to share her knowledge,
[11:19.65]her interest in women's rights,and her medical service during the war.
