Celebrating Marie Curie
Today for international womens day we are celebrating a great woman of science. Marie Curie was the first woman to win the nobel prize and only woman to earn it twice. Born in Poland in 1867 her groundbreaking research led to the discovery of radioactivity and two radioactive elements, Radium and Polonium. In 1915, Curie produced hollow needles containing "radium emanation", a colourless, radioactive gas given off by radium, later identified as radon. Radon breaks down and forms polonium. The Alpha Particles produced by the break down of Radium into Radon, then Radon into Polonium create “radiation” which is harmful to health if ingested or absorbed.
