Polonium

Pierre and Marie Curie discoveries and prize

In 1903

Radium

Polonium (1898)

• radiochemical analysis
• named after Marie Curie's homeland
• extremely rare : 1,000 tons of ore (= minerai) = 40mg of polonium
• electrical conductivity decreases as the temperature increases = metals
• highly radioactive
• used industrially to eliminate static electricity + removing dust from photographic film + source of alpha radiation

Radium (1898)

• silvery white metal
• 1902, 0.1 gram of pure radium chloride was prepared by refining several tons of pitchblende residues
• 1910: Marie Curie and André-Louis Debierne(A French chemist, discoverer of actinium) had isolated the metal itself
• heaviest of the alkaline earths
• 1 gram of radium-226 undergoes 3.7 × 1010 disintegrations per second
• used in medecine for the treatment of cancer by subjecting tumours to the gamma radiation

Radium experiment

Achievements

• 1906: First physician woman to be a professor at the Sorbonne
• 1909: own lab at the university of Paris
• 1911: nobel prize in chemistry
• only person to win the Nobel Prize in two different sciences areas

Save life

• polonium + radium = radioactiv elements -> invisible rays that could pass through solid matter and conduct electricity

=> the x-ray take stronger and more accurate pictures inside the human body

• She created mobile x-ray units (= Little Curies) that could be driven to battlefield hospitals in France
• Doctors could see broken bones and bullets inside wounded soldiers’ bodies
• Over 1 million wounded soldiers were treated

During

the first world war

Received by U.S. President Warren G. Hardingat the White House

1921

Visited Poland to participate in a ceremony laying the foundations for Warsaw's Radium Institute

1925

Was awarded the Cameron Prize for Therapeutics of the University of Edinburgh

1931

Died of a disease caused by radiation

1934

She had proven that women could make breakthroughs in science, and today she continues to inspire scientists to use their work to help other people
