1. What Are Radioactive Materials? - Definition, Examples, Uses & Benefits
Radioactive materials are all around us. Some are beneficial, while others may cause us harm. In this lesson you'll learn what radioactive materials are and explore where they come from and how they can be useful to us.
2. Types of Radioactive Decay and Their Effect on the Nucleus
What is meant by the term 'radioactive'? In this lesson we will break down the three main types of nuclear decay particles and discuss their composition, their effect on the nucleus, and their applications.
3. Principles of Radiometric Dating
Radiometric dating is a method used to determine the age of rocks and other materials based on the rate of radioactive decay. Learn about three common types of radioactive decay: alpha decay, beta decay and gamma decay.
4. Nuclear Reaction: Definition & Examples
Learn the differences between a nuclear reaction and a chemical reaction. Also learn how the nuclear reaction involves subatomic particles including protons and neutrons. Discover the different types of nuclear reactions including fission and fusion and also how a nuclear power plant works to produce energy.
5. Risks of Nuclear Power Plants and Radioactive Waste: Safety and Health Concerns
Nuclear power can generate electricity without greenhouse gas emissions. However, there are concerns about its safety. Learn about the safety and health concerns associated with the threat of nuclear meltdowns, as well as the challenges involved in storing radioactive waste.
