Nuclear Energy and Radiation

Subject: General Science

Book: NCERT Science Class 10

Nuclear energy is obtained from nuclear reactions.
- **Types of Nuclear Reactions**:
- Fission: Splitting of heavy atoms (e.g., Uranium).
- Fusion: Combining of light atoms (e.g., Hydrogen in the Sun).
- **Advantages of Nuclear Energy**:
- High energy output, low greenhouse gas emissions.
- **Dangers**:
- Radiation hazards, nuclear waste disposal.

**Possible Exam Questions:**
1. Differentiate between nuclear fission and fusion.
2. How does a nuclear power plant work?
3. What are the benefits and risks of nuclear energy?
4. Discuss the impact of nuclear waste on the environment.
5. Why is nuclear fusion not yet widely used for energy production?
