Study Notes
Marie Curie: Pioneer of Radioactivity
- Henri Becquerel discovered natural radioactivity in 1896, observing uranium emitting radioactive particles.
- Marie Curie, following this discovery, isolated pure radium in 1910, winning a Nobel Prize in chemistry for this work in 1911.
- She coined the term "radioactivity" describing energy release from atom disintegration.
- Curie was unaware of the dangers of radioactive substances, handling samples and storing them, leading to radiation sickness.
Curie's Contributions During World War I
- Curie used her Nobel Prize money to create mobile X-ray units ("Petites Curies") for wounded soldiers in World War 1.
- Curie and her daughter, Irène, assisted in treating the wounded using X-rays
- Curie established the Curie Foundation, pioneering cancer research using radium.
Dangers of Radioactivity
- Marie Curie's work on radioactivity, while groundbreaking, led to her developing radiation sickness.
- Prolonged exposure to radiation ultimately caused her death at age 66 from aplastic anemia.
- The medical dangers of too much radiation were highlighted during her research.
Cost of Radium
- One gram of radium cost $100,000 in 1921.
