Marie Curie and Radioactivity

In 1896, Henri Becquerel discovered radiation by accident while experimenting with uranium and photographic plates. Despite an overcast day, he found that uranium emitted radiation without sunlight. Marie and Pierre Curie furthered this research, discovering radium and polonium, and were awarded the Nobel Prize in Physics in 1903. Marie Curie also won a Nobel Prize in Chemistry, becoming the first woman to win a Nobel Prize and the only person to win in two different fields. The Curies' work laid the foundation for understanding radiation, though they were unaware of its dangers at the time.

What was Henri Becquerel's initial hypothesis about uranium?

• It would change color under sunlight.

• It would emit x-rays when exposed to sunlight.

• It could be used to develop photographs.

• It could emit light in the dark.

What did Becquerel initially use to test his hypothesis about uranium?

• A photographic plate wrapped in black paper

• A microscope

• A Geiger counter

• A telescope

What unexpected event led Becquerel to discover radiation?

• A sunny day that developed the plates.

• An overcast day that prevented his experiment.

• A power outage that affected his equipment.

• A chemical reaction with the plates.

What did Marie Curie decide to call the radiation discovered by Becquerel?

• Radiation

• Curie Rays

• X-rays

• Becquerel Rays

Which element did Marie Curie discover that emitted more radiation than uranium?

• Plutonium

• Thorium

• Radium

• Polonium

What did Marie Curie name the second element she discovered?

• Radium

• Polonium

• Uranium

• Thorium

What was the significance of Marie Curie's Nobel Prize achievements?

• She won the most Nobel Prizes in history.

• She was the first person to win a Nobel Prize.

• She was the first woman to win a Nobel Prize and the only person to win in two different sciences.

• She was the youngest Nobel Prize winner.

What was a major realization about radiation after the Curie's research?

• It could be harmful and required precautions.

• It was completely safe to handle.

• It had no practical applications.

• It was only emitted by uranium.

How did the Curie's handle radioactive materials during their research?

• By using remote handling tools.

• Without any protective measures.

• By storing them in lead containers.

• With protective gear and equipment.

What is the current state of the Curie's notebooks?

• They are displayed in a museum.

• They are still highly radioactive.

• They have been decontaminated.

• They were lost during World War II.
