What is nuclear fusion?

• Nuclear fusion involves the splitting of heavy atomic nuclei

• Nuclear fusion is a process that does not release energy

• Nuclear fusion is a type of nuclear fission

• Nuclear fusion is a process where two light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy in the process.

Explain the process of radioactive decay.

• Radioactive decay is a reversible process that can be controlled.

• Radioactive decay is a chemical reaction involving the release of electrons.

• Radioactive decay is the process of creating new elements from existing ones.

• Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation.

How do nuclear reactors work?

• Nuclear reactors use wind energy to produce electricity.

• Nuclear reactors rely on solar power for their operation.

• Nuclear reactors generate heat through controlled nuclear fission reactions to produce electricity.

• Nuclear reactors work by burning fossil fuels to generate heat.

What is nuclear energy and how is it produced?

• Nuclear energy is produced through nuclear fission, where atoms are split to release heat energy that is used to generate electricity.

• Nuclear energy is generated through photosynthesis.

• Nuclear energy is created by harnessing wind power.

• Nuclear energy is produced by burning fossil fuels.

Define isotopes and provide an example.

• Isotopes are atoms of different elements with the same number of protons.

• An example of isotopes is Hydrogen-1 and Helium-2.

• Isotopes have the same number of protons and electrons.

• Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. An example of isotopes is Carbon-12 and Carbon-14.

What are the advantages of nuclear fusion as an energy source?

• Abundant fuel supply, low environmental impact, high energy output, inherent safety features

• Unreliable fuel supply, significant environmental impact, low energy output, lack of safety measures

• Limited fuel supply, high environmental impact, low energy output, lack of safety features

• Expensive fuel supply, minimal environmental impact, moderate energy output, safety concerns

What are the different types of radioactive decay?

• zeta decay

• alpha decay, beta decay, and gamma decay

• delta decay

• epsilon decay

What are the main components of a nuclear reactor?

• fuel rods, control rods, moderator, coolant, reactor vessel, shielding

• thorium rods, control rods, moderator, coolant, reactor core, containment

• plutonium rods, control rods, moderator, coolant, reactor vessel, insulation

• uranium rods, control rods, moderator, coolant, reactor core, shielding

How do isotopes play a role in nuclear medicine?

• Isotopes are not used in nuclear medicine

• Isotopes are only used in surgery, not imaging

• Isotopes have no impact on medical procedures

• Isotopes emit radiation that can be detected in imaging techniques.

What are the safety measures in place for nuclear reactors?

• No coolant systems, no emergency shutdown, no containment buildings

• Control rods, coolant systems, containment buildings, emergency shutdown systems

• Open-air cooling, no containment, manual control rods

• Lead pipes, wooden walls, no emergency systems
