Both Curies were constantly ill from radiation sickness, and Marie Curie's death from aplastic anemia in 1934, at age 66, was likely caused by radiation exposure. A few of her books and papers are still so radioactive that they are stored in lead boxes.

Why are Marie Curie’s remains radioactive?

Marie Curie died in 1934 of aplastic anemia (likely due to so much radiation exposure from her work with radium). Marie's notebooks are still today stored in lead-lined boxes in France, as they were so contaminated with radium, they're radioactive and will be for many years to come.

Is Madame Curie still radioactive?

Now, more than 80 years since her death, the body of Marie Curie is still radioactive. The Panthéon took precautions when interring the woman who coined radioactivity, discovered two radioactive elements, and brought X-rays to the frontlines of World War I.

How did Marie Curie discover radioactivity?

On April 20, 1902, Marie and Pierre Curie successfully isolate radioactive radium salts from the mineral pitchblende in their laboratory in Paris. In 1898, the Curies discovered the existence of the elements radium and polonium in their research of pitchblende.

What happens if you touch polonium?

Polonium is a metal found in uranium ore whose isotope polonium-210 is highly radioactive, emitting tiny positively charged alpha particles. So long as polonium is kept out of the human body, it poses little danger because the alpha particles travel no more than a few centimeters and cannot pass through skin.

How radioactive are Marie Curie’s books?

Curie's notebooks contain radium (Ra-226) which has a half-life of approximately 1,577 years. This means that 50 percent of the amount of this element breaks down (decays) in approximately 1,600 years.

What happened to Marie Curie’s lab?

The University of Paris built Curie a lab in 1933 in Arcueil, south of Paris. The lab closed in 1978, and now it's known as Chernobyl on the Seine, explains Bloomberg Businessweek. Curie herself died from aplastic anemia, which is linked to prolonged radiation exposure.

Who accidentally discovered radioactivity?

physicist Henri Becquerel In one of the most well-known accidental discoveries in the history of physics, on an overcast day in March 1896, French physicist Henri Becquerel opened a drawer and discovered spontaneous radioactivity.

Why is radium radioactive?

Radium (chemical symbol Ra) is a naturally occurring radioactive metal. Radium is a radionuclide formed by the decay of uranium and thorium in the environment. The most common isotopes. For example, uranium has thirty-seven different isotopes, including uranium-235 and uranium-238.

Can I buy polonium?

Yes, Polonium-210, "which experts say is many times more deadly than cyanide," the story notes, "can be bought legally through United Nuclear Scientific Supplies, a mail-order company that sells through the Web.
