What Are Radioactive Materials? - Definition, Examples, Uses & Benefits

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.

Types of Radioactive Decay and Their Effect on the Nucleus

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.

Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

3. Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

What causes a radioactive particle to decay? We'll never really know, but our best guess lies in probability. In this lesson, we are going to focus on the half-life, a way of measuring the probability that a particle will react.

Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry

4. Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry

What can the sun do that we can't? How do carbon atoms 'date'? Are radioactive isotopes helpful in the medical field? The answers to these questions can be found in this lesson on the applications of nuclear chemistry.

Critical Mass & Controlling Chain Reactions

5. Critical Mass & Controlling Chain Reactions

Learn about critical mass in the context of nuclear reactors, as well as how we can manage nuclear chain reactions using control rods and water cooling. After the lesson, see how much you've learned by taking a quiz.

Background Radiation: Definition, Causes & Examples

6. Background Radiation: Definition, Causes & Examples

This lesson will define background radiation, explain how it is measured, discuss some of the sources and examples of background radiation, and briefly consider the risk to humans. A short quiz will follow.
