Nuclear Energy TOD

Front

What is nuclear energy?

Back

Nuclear energy is the energy released during nuclear fission or fusion, especially when used to generate electricity.

Front

What is the half-life of a radioactive isotope?

Back

The half-life is the time required for half of the nuclei in a sample of a radioactive isotope to decay.

Front

How does radioactive decay occur?

Back

Radioactive decay occurs when unstable atomic nuclei lose energy by emitting radiation, resulting in the transformation into a different element or isotope.

Front

What is a beta particle?

Back

A beta particle is a high-energy, high-speed electron or positron emitted during radioactive decay.

Front

What happens to the mass of a radioactive sample over time?

Back

The mass of a radioactive sample decreases over time as the isotopes decay into other elements or isotopes.

Front

What is the significance of Barium-122's half-life in experiments?

Back

The half-life of Barium-122 (5 minutes) indicates how quickly the sample will decay, affecting the amount available for experiments.

Front

What are some advantages of nuclear energy?

Back

Advantages of nuclear energy include low greenhouse gas emissions, high energy density, and a reliable power supply.

Front

What are some disadvantages of nuclear energy?

Back

Disadvantages include the potential for catastrophic accidents, radioactive waste disposal issues, and high initial costs.

Front

What isotope is produced when Cesium-137 decays?

Back

When Cesium-137 undergoes radioactive decay, it produces Barium-137.

Front

What is the relationship between half-life and radioactive decay?

Back

The half-life is a measure of the rate of radioactive decay; shorter half-lives indicate faster decay rates.
