<ul><li> Slide 1 </li> <li> Madame Marie Curie &amp; The Science of Radioactivity By Claire Goelst </li> <li> Slide 2 </li> <li> Early Life Born on November 7, 1867 in Warsaw, Poland Given name was Marya Sklodowska, but her family and friends called her Little Manya </li> <li> Slide 3 </li> <li> Early Life cont. Her father was a professor of math and physics Her mother was a pianist, singer, and teacher Her mother died of tuberculosis when Marya was 11 </li> <li> Slide 4 </li> <li> Schooling Graduated high school when she was 15 In 1891 she enrolled at the Sorbonne in Paris as Marie and graduated in 1893 </li> <li> Slide 5 </li> <li> Pierre She married Pierre Curie in July 1895 </li> <li> Slide 6 </li> <li> Thesis Work She decided that her thesis for her doctorate would be on Henri Becquerels mysterious x- rays that are given off by uranium </li> <li> Slide 7 </li> <li> Work with Uranium Discovered that if you have a certain amount of uranium, then you get a certain amount of ray intensity, no matter what you did to the material </li> <li> Slide 8 </li> <li> Uranium Continued Marie discovered that there was something going on inside the atom that created the rays, she named this effect radioactivity </li> <li> Slide 9 </li> <li> She discovered that the only known elements that were radioactive were uranium and thorium Radioactivity </li> <li> Slide 10 </li> <li> Polonium Pierre stopped his work on crystals to work with Marie Marie continued her work, but with a different substance, pitchblende </li> <li> Slide 11 </li> <li> Polonium Cont. They called this new substance polonium in honor of Maries homeland In July 1898 they extracted a new element that was even more radioactive than uranium </li> <li> Slide 12 </li> <li> Radium In January of 1899 another new element was discovered that was over 1 million times more radioactive than uranium, it was named radium </li> <li> Slide 13 </li> <li> Radium Continued In 1910 Marie isolated pure radium metal Her major studies showed that radium gave out light and heat, as well as being able to damage living flesh </li> <li> Slide 14 </li> <li> Radium cont. In order to obtain one decigram of pure radium chloride salt, Marie had to sift through hundreds of tons of pitchblende </li> <li> Slide 15 </li> <li> Properties of Radium Radium is silver-white in color Today it is used in small amounts as a cancer treatment and in fluorescent paint </li> <li> Slide 16 </li> <li> Pierres Death Pierre Curie was killed tragically by a horse-drawn cart in 1906 </li> <li> Slide 17 </li> <li> Teaching It was decided that Marie should take over Pierres teaching job at the Sorbonne in 1906 This made Marie the 1st woman professor at any French university </li> <li> Slide 18 </li> <li> Paris Radium Institute In 1907 Marie convinced the French government to fund a radium research institute, to be used mainly for medical research </li> <li> Slide 19 </li> <li> Health Problems Marie believed that working with radium was not a danger to her health, however, doctors today have proven that she was very wrong </li> <li> Slide 20 </li> <li> Health cont. In 1911 Marie collapsed from depression and severe kidney problems that were a result of her long- time exposure to radium </li> <li> Slide 21 </li> <li> Radium Institute cont. In August 1914 the Radium Institute was finished, and named after Maries deceased husband </li> <li> Slide 22 </li> <li> World War II Shortly after the institute was finished, Germany invaded France Maries staff was cut short to two people, herself and her daughter Irene </li> <li> Slide 23 </li> <li> World War II cont. Immediately after the War broke out Marie donated all of her money to the War fund, and signed up to be a nurse </li> <li> Slide 24 </li> <li> X-ray Mobiles Marie decided that there should be x-ray machines that the war doctors could use on the battle field for soldiers </li> <li> Slide 25 </li> <li> X-ray mobiles cont. Marie created 20 mobile x-ray machines and over 200 stationary machines </li> <li> Slide 26 </li> <li> Radon Marie also invented tiny glass tubes that were filled with radon ( a radioactive gas) </li> <li> Slide 27 </li> <li> Radon cont. Doctors would insert the tubes in patients at spots where the radiation would destroy diseased tissue </li> <li> Slide 28 </li> <li> After the War After the War ended in 1918 Marie spent a lot of time with her two daughters Irene and Eve </li> <li> Slide 29 </li> <li> After the War cont. After two or three years with her daughters she resumed her work with radium at the Paris institute </li> <li> Slide 30 </li> <li> Declining Health Marie had been working at the radium institute in good health for almost 12 years She began to notice burns on her hands and her failing eyesight somewhere around 1932 </li> <li> Slide 31 </li> <li> Late Life Maries blood had been weakened by her constant exposure to radium This caused her to catch aplastic anemia </li> <li> Slide 32 </li> <li> Late Life cont. Marie eventually contracted leukemia and died on July 14, 1934 </li> <li> Slide 33 </li> <li> Awards Marie was awarded numerous small awards during her life such as having her picture placed on a stamp! </li> <li> Slide 34 </li> <li> Awards cont. Marie was awarded the Nobel prize in physics in 1903 for her work with X- rays She was also awarded the Nobel prize in chemistry in 1911 for her work with radium </li> <li> Slide 35 </li> <li> About Me!!! Hi!Im Claire! I like food-all kinds. And I like horses, chickens(yes a little odd I know), and talking!!!!!! Im incredibly tall and I have red hair!!!!
