Why didn't people in Marie Curie's time realize radioactivity could be harmful?

• Most people back then were poorly educated

• People had experimented with it for centuries with no ill effects

• The Curies made several errors in their experiments

• It had just been discovered, and all its properties were not yet known

What can you infer from the fact that Marie Curie named a new element after her home country of Poland?

• That she never wanted to set foot in Poland again

• That she was working for the Polish government at the time

• That she was proud of her heritage, in spite of the discrimination she faced

• That she disliked living in France

What made Marie Curie suspect that pitchblende contained more radioactive elements than just uranium?

• It gave off more radiation than uranium alone

• The decay rate of uranium would speed up once it was separated from pitchblende

• It gave off less radiation than uranium alone

• Its color

Marie Curie is one of just a handful of women who have ever won a Nobel Prize for either chemistry or physics. What can you infer from this?

• Despite many gains in the sciences, there are still relatively few female chemists and physicists

• Marie Curie is the only woman who will ever win two Nobel Prizes

• It is common today for women to excel in the field of chemistry, but not in physics

• Women have not made many major advances in science since Curie's first Nobel Prize in 1903

With her husband Pierre, Marie created the term...

• radioactivity

• X-rays

• X-men

• stereoactivity
